Abstract:

Cochlear implant users are known to have limited access to spatial cues. This study investigated the perception of spatial cues in normal-hearing listeners and cochlear implant simulation users. Perception of spatial cues is assessed for performance in determining the direction of the sound and understanding the speech. The results show that cochlear implant simulation users still have access to spatial cues, just like normal- hearing listeners. Normal-hearing listeners and cochlear implant simulation users can perceive spatial cues in ILD and ITD. Both can accurately identify the direction of the sound (slope ≈ 1.00 and of set ≈ 0.00°). Cochlear implant simulation users can understand sentences as well as normal-hearing listeners (PCW = 113.64 rau) by using the coding strategy SPEAK in all channels or CIS with channel above 8. Perception of spatial cues in normal-hearing listeners and cochlear implant users can be improved by listening with two ears and spatially separating the target-masker position. The largest improvement in spatial cue perception was obtained from the head shadow effect (normal-hearing (NH) = 12.96, cochlear implant simulation users (CI) = 59.02), followed by binaural summation (NH = 5.72, CI = 19, 86) and binaural squelch (NH = 3.76, CI = 7.66).

Abstract:

Purpose: The ability to benefit from spatial separation between target and masker signals is important in multi-sound source listening environments. The goal of this study was to measure the spatial release from masking (SRM) in unilateral cochlear implant (CI) users with bilateral profound hearing loss. We also determined the relationships between the SRMs and the self-reported spatial hearing abilities.Methods: Fourteen unilateral CI users with bilateral profound hearing loss participated in this study. The target sentence was always presented to the front of the listener, and the nonfluctuating speech-shaped noise (SSN) or fluctuating speech noise was either co-located with the target (speech at 0°, noise at 0°, S0N0) or spatially separated at ± 90°. The SRM was quantified as the difference between speech recognition thresholds (SRTs) in the co-located and spatially separated conditions. The self-reported spatial hearing abilities were also measured using validated subjective questionnaires.Results: Overall, the SRTs were lower (better) with SSN than with fluctuating speech noise. When the noise was presented to the non-CI ear (speech at 0°, noise at non-CI ear, S0Nnonci), speech-in-noise recognition was the greatest due to head shadow or better-ear listening effect, resulting in the SRMs of approximately 5~6 dB regardless of noise type. When the noise was given to the CI ear (speech at 0°, noise at CI ear, S0Nci), some individuals exhibited positive SRMs (3~8 dB), while others showed negative SRMs, leading to little SRMs overall. When the SSN was given, subjects with less SRMs (less spatial separation benefits on the objective test) reported greater subjective spatial hearing difficulties.Conclusion: The spatial hearing of unilateral CI users varied by the position of the sound source. Listeners' spatial hearing abilities, which are unpredictable from clinical routine tests, need to be assessed by either objective or subjective measures.

Abstract:

Relationships between extended high-frequency (EHF) thresholds and speech-in-spatialized noise were examined in firefighters with a history of occupational noise and airborne toxin exposure. Speech recognition thresholds were measured for co-located and spatially separated (±90° azimuth) sentences in a competing signal using the Listening in Spatialized Noise–Sentences test. EHF hearing was significantly correlated with the spatial advantage, indicating that firefighters with poorer EHF thresholds experienced less benefit from spatial separation. The correlation between EHF thresholds and spatial hearing remained significant after controlling for age. Deficits in EHF and spatial hearing suggest firefighters may experience compromised speech understanding in job-related complex acoustic environments.

Abstract:

The spatial hearing in patients with mild and moderate symmetrical chronic sensorineural hearing loss (SNHL) was studied using the Russian-language version of the Spatial hearing questionnaire (SHQ). 141 patients aged 47 to 82 years were examined. The comparative analysis was performed in the groups of age-related normal hearing, mild SNHL, moderate SNHL. A significant deterioration in spatial perception was shown, revealed by the results of the survey in both groups with SNHL, and the mild and moderate hearing loss groups significantly differed in some indicators. The deterioration of spatial perception revealed by the analysis of the subscales of the questionnaire and the quantitative estimates of spatial and temporal resolution obtained earlier with mild and moderate degrees SNHL were in good agreement. With moderate SNHL, the scores of all four subscales of the questionnaire were significantly reduced. In clinical practice, this questionnaire can be used as a screening method for assessing spatial hearing in patients with SNHL.

Abstract:

Purpose: This study investigated whether auditory spatial training using multi-talker speech and real-life background noise can improve speech-in-noise intelligibility in adult hearing aid users.Methods: Twenty-eight hearing aid users participated in this study. Fifteen adults underwent auditory spatial training, while the remaining 13 served as a non-trained control group. The trained participants completed an 8-week in-laboratory auditory spatial training program. During the training, target sentences recorded by 40 different talkers were presented with real-life environmental noise. The target speech and background noise were spatially separated, with spatial uncertainty introduced regarding their locations. The performance of trained and non-trained listeners was compared to assess the effectiveness of the auditory spatial training. Objective evaluation was conducted using the Korean Matrix sentence-in-noise recognition test in a sound-field condition, where speech and noise were spatially co-located or separated. Additionally, the Korean version of the profile of hearing aid benefit quick version was administered to assess subjective hearing aid benefit. All these tests were conducted three times: before training (pre-training), immediately after 8-week training (post-training), and 1 month after the 8-week training (retention).Results: Auditory spatial training significantly improved sentence-in-noise recognition in spatially co-located and separated conditions across all signal-to-noise ratios. The training effects were maintained for up to 1-month post-training. Furthermore, subjective questionnaire responses indicated positive effects of the training.Conclusion: An 8-week auditory spatial training program incorporating multi-talker speech and real-life environmental noise improved spatialized and non-spatialized speech-in-noise intelligibility in adult hearing aid users.

Abstract:

The elderly with hearing loss have often experienced spatial hearing deficits when only wearing hearing aids. This case study aimed to investigate whether auditory training for spatial hearing loss could improve the spatial hearing ability of the elderly who wear hearing aids. Two older adults (males, aged 75 years and 78 years) who were wearing bilateral hearing aids participated. They had symmetric sensorineural hearing loss. A total of 16 auditory-training sessions (40 minutes, twice per week) for auditory training for spatial hearing ability provided. For outcome measurements, we assessed speech reception thresholds (SRTs) and spatial release from masking (SRM), using two types of noise, steady-state noise and speech-like noise at pre- and post-auditory training. Both subjects increased SRTs after the auditory training, but the SRM of only one participant improved. Also, there were no masking effects for SRM in terms of noise types. Both subjects reported that their trained hearing skills helped in communication with their families and friends. These results suggested that audiologists can consider auditory training for focusing on the spatial hearing loss for the elderly hearing aids users.

Abstract:

AbstractIntroduction:Patients receiving a bone-anchored hearing aid have well-documented improvements in their quality of life and audiometric performance. However, the relationship between audiometric measurements and subjective improvement is not well understood.Methods:Adult patients enrolled in the Nova Scotia bone-anchored hearing aid programme were identified. The pure tone average for fitting the sound-field threshold, as well as the better and worse hearing ear bone conduction and air conduction levels, were collected pre-operatively. Recipients were asked to complete the Speech, Spatial and Qualities of Hearing questionnaire; their partners were asked to complete a pre- and post-bone anchored hearing aid fitting Hearing Handicap Inventory for Adults questionnaire.Results:Forty-eight patients who completed and returned the Speech, Spatial and Qualities of Hearing questionnaire had partners who completed the Hearing Handicap Inventory for Adults questionnaire. The results from the Speech, Spatial and Qualities of Hearing questionnaire correlated with the sound-field hearing threshold post-bone-anchored hearing aid fitting and the pure tone average of the better hearing ear bone conduction (total Speech, Spatial and Qualities of Hearing Scale to the pre-operative better hearing ear air curve (r = 0.3); worse hearing ear air curve (r = 0.27); post-operative, bone-anchored hearing aid-aided sound-field thresholds (r = 0.35)). An improvement in sound-field threshold correlated only with spatial abilities. In the Hearing Handicap Inventory for Adults questionnaire, there was no correlation between the subjective evaluation of each patient and their partner.Conclusion:The subjective impressions of hearing aid recipients with regards to speech reception and the spatial qualities of hearing correlate well with pre-operative audiometric results. However, the overall magnitude of sound-field improvement predicts an improvement of spatial perception, but not other aspects of hearing, resulting in hearing aid recipients having strongly disparate subjective impressions when compared to those of their partners.

Abstract:

Purpose The goal of this study was to determine how self-reported spatial hearing abilities differ across various cochlear implant (CI) profiles and to examine the degree of subjective benefit following cochlear implantation across different groups of CI users. Method This was a retrospective study of subjective spatial hearing ability of CI recipients. The subjects consisted of 99 unilateral CI users, 49 bilateral CI users, 32 subjects with a CI and contralateral hearing aid (bimodal users), and 37 short-electrode CI users. All subjects completed the Spatial Hearing Questionnaire (Tyler, Perreau, & Ji, 2009), a questionnaire assessing spatial hearing ability, after implantation, and a subset of the subjects completed the questionnaire pre- and postimplantation. Results Subjective spatial hearing ability was rated higher for the bilateral and short electrode CI users compared to the unilateral and bimodal users. There was no significant difference in subjective spatial hearing performance between the bilateral and short electrode CI users and the unilateral CI and bimodal users. A separate analysis of pre- and postimplant performance revealed that all CI groups reported significant improvements in spatial hearing ability after implantation. Conclusion This study suggests that there are substantial differences in perceived spatial hearing ability among unilateral and bimodal CI users compared with bilateral and short electrode CI users.

Abstract:

Purpose: The present study aimed to identify the overall patterns of spatial hearing in a sample population of the geriatric population wearing a hearing aid in an actual clinical setting and to investigate while paying attention to aging and the effects of spatial separation on informational masking (IM) of target speech of common types of noise in everyday life.Methods: Nine participants (mean age: 68.9 ± 9.6) wearing hearing aids participated. The spatial hearing abilities of the participants were assessed by measuring their speech reception threshold (SRT) and spatial release from masking (SRM), using speech-like (SLN) and steady-state (SSN) noise-maskers.Results: The study results identified a trend in the decrease in SRT in all noise conditions with increasing azimuth angles. The larger the target/masker spatial separation, the larger the SRM became in all noise conditions. Results revealed that geriatric hearing-impaired participants experienced a comparable amount of SRM from IM in SLN concerning SSN.Conclusions: Given these findings, the spatial separation did not have the same effects on the IM of target speech by SLN in the geriatric population wearing a hearing aid as it did in the general hearing-impaired population at younger ages. It can be inferred from these findings that the extent to which informational maskers can compromise the spatial hearing abilities of geriatric hearing-impaired listeners may depend on their age and the severity of spatial hearing loss being imposed on them.

Abstract:

Background: Spatial release from masking (SRM) is the improvement in speech intelligibility when the masking signals are spatially separated from the target signal. Young, normal- hearing listeners have a robust auditory sys-tem that is capable of using the binaural cues even with a very small spatial separation between the target and the maskers. Prior studies exploring SRM through simulated cochlear implant (CI) speech have been completed using substantial spatial separations, exceeding 45° between the target signal and masking signals. Nevertheless, in re-al-world conversational scenarios, the spatial separation between the target and the maskers may be considerably less than what has been previously investigated. This study presents SRM data utilizing simulated CI speech with young, normal-hearing listeners, focusing on smaller but realistic spatial separations between the target and the maskers. Methods: Twenty-five young, normal-hearing listeners participated in this study. Speech identification thresholds, the target-to-masker ratio required to accurately identify 50% of the target words, were measured for both natural speech and simulated CI speech. Results: The results revealed that young, normal-hearing listeners had significantly higher speech identification thresholds when presented with simulated CI speech in comparison to natural speech. Furthermore, the amount of SRM was found to be greater for natural speech than for the simulated CI speech. Conclusions: The data suggests that young normal-hearing individuals are capable of utilizing the interaural level difference cues in the simulated cochlear implant signal to achieve masking release at reduced spatial separations between the target and the maskers, highlighting the auditory system’s capability to extract these interaural cues even in the presence of degraded speech signals.

Abstract:

Purpose Although a number of questionnaires are available to assess hearing aid benefit and general hearing disability, relatively few investigate spatial hearing ability in more complex listening situations. The aim of this study was to document the performance of individuals with normal hearing using the Spatial Hearing Questionnaire (SHQ; Tyler, Perreau, & Ji, 2009) and to compare performance with published data from cochlear implant (CI) users. Method Fifty-one participants with normal hearing participated. All participants completed the 24-item SHQ. Also, a factor analysis and reliability tests were performed. Results Performance on the SHQ was high (87%) for the participants with normal hearing. Subjective ratings varied across different listening situations: Understanding speech in quiet (98%) was rated higher than sound localization (84%) and understanding speech in a background of noise (85%). Compared with previously published data (Tyler, Perreau, & Ji, 2009), listeners with normal hearing rated their spatial hearing ability significantly better than bilateral and unilateral CI users. Results confirmed that the SHQ is a reliable measure of spatial hearing ability for listeners with normal hearing. Conclusions Overall, results indicated that the SHQ is able to capture expected differences between individuals with normal hearing and CI users. These new data can be used as targets following the provision of hearing devices.

Abstract:

Spatial hearing ability enables people with normal hearing to localize a sound source and utilizes the cocktail party effect to detect the target speech information in a noise environment. Hearing-impairment causes not only hearing loss but also the degradation of spatial auditory ability. Hearing aid is desired to improve the spatial auditory ability of some hearing-impaired people, in addition to compensating hearing loss. However, the microphones for conventional behind-the-ear (BTE) hearing aid are located behind the pinnae rather than in the entrances of ear canal, which may cause distortion in spatial cues in the recorded binaural signals. The present work comprehensively evaluates the spatial hearing cues recorded by BTE-microphones. The head-related transfer functions (HRTF) for a KEMAR artificial head and eight human subjects, at three BTE positions and the entrances of blocked ear-canal, are measured respectively. Analysis from the HRTF data indicates that BTE microphone recording basically reserves the interaural time difference and interaural level difference as lateral-direction information. It also reserves the dynamic cues, but obvious distortions appear in the spectral cues at high frequencies. However, due to the redundancy among different spatial information, it can be inferred that dynamic cues alone may provide appropriate front-back and vertical-direction information.

Abstract:

Background and Aims Despite good speech intelligibility in quiet environments, unilateral hearing loss can lead to significant challenges in noisy settings. This is due to the deprivation of binaural spatial cues, crucial for sound localization, lateralization, and speech comprehension in noisy environments. Accordingly, individuals with unilateral hearing loss are suspected of having spatial auditory processing disorders. This study investigates the effects of moderate to profound unilateral hearing loss on spatial auditory processing skills in adults using two validated self-assessment questionnaires. Methods This cross-sectional descriptive analytical study enrolled 60 participants, including 30 adults with moderate to profound unilateral hearing loss (target group) and 30 adults with normal hearing in both ears (control group). Spatial auditory processing skills were assessed using the Persian versions of the speech, spatial, and qualities of hearing scale and the spatial hearing questionnaire. Independent t tests were used for group comparisons, and the Spearman correlation test was applied to examine the relationship between the two questionnaires, considering the non-normal data distribution. Results Significant differences were observed in total and subscale scores on both questionnaires between the target and control groups. The target group (individuals with unilateral hearing loss) demonstrated poorer performance in spatial auditory processing compared to the control group. Meanwhile, a strong correlation was found between the total and subscale scores of the two questionnaires, suggesting consistency in the findings. Conclusion Moderate to profound unilateral hearing loss significantly impacts spatial auditory processing skills. This study provides evidence for the challenges individuals with unilateral hearing loss face in auditory processing tasks, highlighting the need for targeted interventions and support to enhance their listening abilities.

Abstract:

Purpose The purpose of this study was to characterize spatial hearing abilities of children with longstanding unilateral hearing loss (UHL). UHL was expected to negatively impact children's sound source localization and masked speech recognition, particularly when the target and masker were separated in space. Spatial release from masking (SRM) in the presence of a two-talker speech masker was expected to predict functional auditory performance as assessed by parent report. Method Participants were 5- to 14-year-olds with sensorineural or mixed UHL, age-matched children with normal hearing (NH), and adults with NH. Sound source localization was assessed on the horizontal plane (−90° to 90°), with noise that was either all-pass, low-pass, high-pass, or an unpredictable mixture. Speech recognition thresholds were measured in the sound field for sentences presented in two-talker speech or speech-shaped noise. Target speech was always presented from 0°; the masker was either colocated with the target or spatially separated at ±90°. Parents of children with UHL rated their children's functional auditory performance in everyday environments via questionnaire. Results Sound source localization was poorer for children with UHL than those with NH. Children with UHL also derived less SRM than those with NH, with increased masking for some conditions. Effects of UHL were larger in the two-talker than the noise masker, and SRM in two-talker speech increased with age for both groups of children. Children with UHL whose parents reported greater functional difficulties achieved less SRM when either masker was on the side of the better-hearing ear. Conclusions Children with UHL are clearly at a disadvantage compared with children with NH for both sound source localization and masked speech recognition with spatial separation. Parents' report of their children's real-world communication abilities suggests that spatial hearing plays an important role in outcomes for children with UHL.

Abstract:

Acoustic signals can be a source of information affecting workers’ safety in the working environment. Sound perception, directional hearing and spatial orientation of people in the working environment depend on a number of factors, such as acoustic properties of the work room, noise and its parameters, the use of hearing protection, hearing loss or the use of hearing aids. Learning about the impact of these factors on perception, directional hearing and orientation requires using spatial sound and is essential for creating safe working conditions. This article presents basic information about ambisonics, a technique of spatial sound processing, and a test stand developed at the Central Institute for Labor Protection – National Research Institute for research on sound perception, directional hearing and spatial orientation of people using ambisonics.

Abstract:

The human ability for spatial hearing encourages the development of spatial audio technology to support many human activities. Spatial audio mimics the real-life sound and provides a more immersive hearing experience as if the listener were present in the environment where the sound source was recorded. Recently, research on how spatial hearing processes are encoded in the brain has begun to be developed. As a modality for brain activity measurement that is non-invasive and has a high temporal resolution, Electroencephalography (EEG) is suitable for studying brain responses to moving sound stimuli. This study compared brain activity in hearing stereo and spatial audio stimulus. Through measurements using 21 EEG electrodes on the scalp, the results showed an increase in the mean PSD for all Theta, Alpha, and Beta waves in the spatial audio stimulus compared to stereo audio. The most significant increase in the mean PSD occurred in the Beta wave of 93.8008 µV2/Hz. Furthermore, the source localization approach with Independent Component Analysis (ICA) and Low-resolution Brain Electromagnetic Tomography (LORETA) method was used to estimate and quantify the active brain area of this process. The results showed an activation of the non-auditory cortex when the subject was hearing spatial audio stimulus. By using Paired T-Test of current density for both hearing processes, the results showed there was no significant difference (p > 0.05) in Brodmann area (BA) 41 (Primary Auditory Cortex) and BA 42 (Secondary Auditory Cortex). Meanwhile, for the spatial audio hearing process, there was a significant difference (p < 0.05) in BA 6 (Premotor Cortex), which is related to spatial orientation, and BA 9 (Dorsolateral Prefrontal Cortex), which is associated with executive functions, including working memory and selective attention. This study offers potential insights into spatial hearing research and immersive audio production.

Abstract:

A study is reported of the effect of early visual experience on the development of auditory space perception. The spatial hearing of thirty-five children with visual disabilities (twenty-two with congenital total blindness) was compared with that of eighteen sighted children and seventeen sighted adults. The tests provided a comprehensive assessment of spatial-hearing ability, including psychophysical estimates of spatial resolution in the horizontal, vertical, and distance dimensions, as well as measures of reaching and walking to the locations of sound sources. The spatial hearing of the children with visual disabilities was comparable to or some-what better than that of the sighted children and adults. This pattern held even when the group with visual disabilities was restricted to those children with congenital total blindness; in fact, some of those children had exceptionally good spatial hearing. These findings imply that the developmental calibration of human spatial hearing is not dependent on a history of visual experience. It seems likely that this calibration arises from the experience of changes in sound-localization cues arising from self-motion, such as turning the head or walking. As a practical matter, orientation and mobility instructors may reasonably assume that individuals with visual disabilities can use their hearing effectively in day-to-day travel situations.

Abstract:

Background: Spatial hearing questionnaire (SHQ) is a questionnaire developed and validated for evaluating the spatial hearing abilities for the tasks of localization of sound to complex task of speech perception in noise. SHQ is adapted in Dutch language, and in Persian language. The study aimed to compare the spatial hearing abilities of children using bimodal cochlear implant and unilateral cochlear implant using spatial hearing questionnaire a subjective assessment tool, SHQ. Methods: The participants of the study included parents of 30 cochlear implant using children of age range 5-10 years, among 30 participants, 16 belonged to parents of children using unilateral cochlear implant and 14 were parents of children using bimodal cochlear implants. SHQ consisted of 24 questions distributed under 8 domains and the responses from the parents were collected over telephonic interview and statistically analyzed across domains. Results: The results revealed that there was no significant difference observed between both the groups across all the 8 domains, except perception of children’s voice, showed statistical difference between 2 groups. The baseline of spatial skills in children population using unilateral and bimodal cochlear implants was analysed. Conclusions: Across the 8 domains of spatial hearing questionnaire there were no significant statistical difference found between unilateral and bimodal cochlear implanted groups.

Abstract:

The use of sound field synthesis for hearing research has gained popularity due to the ability to auralize a wide range of sound scenes in a controlled and reproducible way. We are interested in reproducing acoustic environments for interactive hearing research, allowing participants to move freely over an extended area in the reproduced sound field. While the physically accurate sound field reproduction using sound field synthesis is limited to the sweet spot, it is unclear how different perceptual measures vary across the reproduction area and how suitable sound field synthesis is to evaluate them. To investigate the viability of listening experiments and provide a database for modelling approaches, measurements of binaural cues were carried out in the Simulated Open Field Environment loudspeaker array. Results show that the binaural cues are reproduced well close to the center, but exhibit more variance than in the corresponding free field case. Off center, lower interaural coherence is observed, which can affect binaural unmasking and speech intelligibility. In this work, we study binaural cues and speech reception thresholds over a wide area in the loudspeaker array to investigate the feasibility of psychoacoustic experiments involving speech understanding.

Abstract:

Introduction Electric–acoustic stimulation (EAS) provides cochlear implant (CI) recipients with preserved low-frequency acoustic hearing in the implanted ear affording auditory cues not reliably transmitted by the CI including fundamental frequency, temporal fine structure, and interaural time differences (ITDs). A prospective US multicenter clinical trial was conducted examining the safety and effectiveness of a hybrid CI for delivering EAS. Materials and Methods Fifty-two adults (mean age 59.9 yr) were enrolled in the study and followed up to 5 years postactivation. Testing included unaided and aided audiometric thresholds, speech perception (Consonant–Nucleus–Consonant [CNC] words in quiet and AzBio sentences +5 dB SNR), and patient-reported outcomes (Speech, Spatial, and Qualities of Hearing Scale). Results Functionally aidable hearing, defined as low-frequency pure-tone average (125–500 Hz) <80 dB HL, was maintained for 77% of patients through 1 year, with 66.7% maintaining through 5 years. Speech perception was significantly improved at all postoperative timepoints compared with preoperative performance with hearing aid(s), and patient-reported outcomes indicated significantly improved subjective speech understanding, spatial hearing, and sound quality. Participants with preserved acoustic hearing using EAS reported significantly higher subjective spatial hearing and sound quality than participants with electric-only hearing in the implanted ear. Discussion Patients with high-frequency hearing loss demonstrate significant long-term benefit with a hybrid CI including high rates of functional hearing preservation, significantly improved speech perception, and subjective patient-reported outcomes. EAS with binaural acoustic hearing affords benefit for subjective spatial hearing and sound quality beyond CI listening configurations using monaural acoustic hearing.

Abstract:

Late reverberation involves the superposition of many sound reflections, approaching the properties of a diffuse sound field. Since the spatially resolved perception of individual late reflections is impossible, simplifications can potentially be made for modelling late reverberation in room acoustics simulations with reduced spatial resolution. Such simplifications are desired for interactive, real-time virtual acoustic environments with applications in hearing research and for the evaluation of hearing supportive devices. In this context, the number and spatial arrangement of loudspeakers used for playback additionally affect spatial resolution. The current study assessed the minimum number of spatially evenly distributed virtual late reverberation sources required to perceptually approximate spatially highly resolved isotropic and anisotropic late reverberation and to technically approximate a spherically isotropic sound field. The spatial resolution of the rendering was systematically reduced by using subsets of the loudspeakers of an 86-channel spherical loudspeaker array in an anechoic chamber, onto which virtual reverberation sources were mapped using vector base amplitude panning. It was tested whether listeners can distinguish lower spatial resolutions of reproduction of late reverberation from the highest achievable spatial resolution in different simulated rooms. The rendering of early reflections remained unchanged. The coherence of the sound field across a pair of microphones at ear and behind-the-ear hearing device distance was assessed to separate the effects of number of virtual sources and loudspeaker array geometry. Results show that between 12 and 24 reverberation sources are required for the rendering of late reverberation in virtual acoustic environments.

Abstract:

Spatial cues can facilitate segregation of target speech from maskers. However, in clinical practice, masked speech understanding is most often evaluated using co-located speech and maskers (i.e., without spatial cues). Many hearing aid centers in France are equipped with five-loudspeaker arrays, allowing masked speech understanding to be measured with spatial cues. It is unclear how hearing status may affect utilization of spatial cues to segregate speech and noise. In this study, speech reception thresholds (SRTs) for target speech in “diffuse noise” (target speech from 1 speaker, noise from the remaining 4 speakers) in 297 adult listeners across 9 Audilab hearing centers. Participants were categorized according to pure-tone-average (PTA) thresholds: typically-hearing (TH; ≤ 20 dB HL), mild hearing loss (Mild; >20 ≤ 40 dB HL), moderate hearing loss 1 (Mod-1; >40 ≤ 55 dB HL), and moderate hearing loss 2 (Mod-2; >55 ≤ 65 dB HL). All participants were tested without aided hearing. SRTs in diffuse noise were significantly correlated with PTA thresholds, age at testing, as well as word and phoneme recognition scores in quiet. Stepwise linear regression analysis showed that SRTs in diffuse noise were significantly predicted by a combination of PTA threshold and word recognition scores in quiet. SRTs were also measured in co-located and diffuse noise in 65 additional participants. SRTs were significantly lower in diffuse noise than in co-located noise only for the TH and Mild groups; masking release with diffuse noise (relative to co-located noise) was significant only for the TH group. The results are consistent with previous studies that found that hard of hearing listeners have greater difficulty using spatial cues to segregate competing speech. The data suggest that speech understanding in diffuse noise provides additional insight into difficulties that hard of hearing individuals experience in complex listening environments.

Abstract:

Aim to validate the Russian version of the Spatial Hearing Questionnaire (SHQ) used for clarifying the spatial hearing impairment, translated from English and adapted. Material and methods. After cultural and linguistic adaptation, the reliability of the Russian version of SHQ was validated using the "test - retest" method in 35 people (mean age 51,215,6 years) in two groups: group I - people with normal hearing (17 people), group II - persons with chronic sensorineural hearing loss levels I-IV (18 people). Results. The reliability was assessed by -Cronbach and was equal to 0.981, the total correlation values 0.68 - 0.92. There was a statistically significant difference (p0.05) between mean SHQ scores in the two groups. Conclusion. Based on the results of our study, the Russian version of the SHQ can be used in practice of an otorhinolaryngologist as an additional diagnostic tool for spatial hearing disorders and during the hearing rehabilitation.

Abstract:

Objective: This article describes the initial development of a novel approach for training hearing-impaired listeners to improve their ability to understand speech in the presence of background noise and to also improve their ability to localize sounds. Design: Most people with hearing loss, even those well fit with hearing devices, still experience significant problems understanding speech in noise. Prior research suggests that at least some subjects can experience improved speech understanding with training. However, all training systems that we are aware of have one basic, critical limitation. They do not provide spatial separation of the speech and noise, therefore ignoring the potential benefits of training binaural hearing. In this paper we describe our initial experience with a home-based training system that includes spatially separated speech-in-noise and localization training. Results: Throughout the development of this system patient input, training and preliminary pilot data from individuals with bilateral cochlear implants were utilized. Positive feedback from subjective reports indicated that some individuals were engaged in the treatment, and formal testing showed benefit. Feedback and practical issues resulted from the reduction of an eight-loudspeaker to a two-loudspeaker system. Conclusions: These preliminary findings suggest we have successfully developed a viable spatial hearing training system that can improve binaural hearing in noise and localization. Applications include, but are not limited to, hearing with hearing aids and cochlear implants.

Abstract:

In daily life, our heads are in continual motion, but much of our knowledge of spatial hearing is based on experimental paradigms in which this behavior is discouraged or prevented. Head motion can benefit spatial hearing though the creation of dynamic acoustical cues, but also creates challenges such as the need to update head-centered spatial representations or the locus of spatial auditory attention. To utilize acoustic information generated by, or to compensate for, head movements, the auditory system must integrate self-motion information provided by other sensory systems. This presentation will review and contextualize a series of studies from the author's laboratory focused on the psychophysics of dynamic sound localization and the weighting of sensory information from vestibular, proprioceptive, and visual modalities in dynamic localization and maintenance of spatially selective auditory attention during head rotation. Notable findings include a velocity-independent ∼100-ms minimum stimulus duration for disambiguation of front/rear location in dynamic localization and the apparent dominance of vestibular information in the interpretation of dynamic localization cues and in attentional updating. The approach taken provides a step towards understanding the effects of naturalistic behavior on spatial hearing while maintaining significant experimental control and repeatability of stimuli and head movements.

Abstract:

Purpose: This study examined the spatial separation benefit (SSB) and fluctuating masker benefit (FMB) for sentence-in-noise recognition in normal-hearing (NH) and hearing-impaired (HI) listeners.Methods: Twenty NH listeners and 10 HI listeners who were regular hearing-aid wearers participated in this study. To measure the SSB and the FMB, the Korean Matrix sentence-in-noise scores were obtained using different types of noise (steady-state speech-shaped noise, three sinusoidally amplitude-modulated noises) when the noise was colocated with the target source or was spatially separated by 30° or 60°.Results: For the NH group, the spatial separation between the target and masker was beneficial, regardless of the type of noise. Among the four types of noise, NH listeners performed poorer with speech-shaped noise than with other modulated noises, yielding a substantial improvement in speech-in-noise resulting from the masker’s fluctuation. The amount of SSB or FMB depended on the signal-to-noise ratios for the NH listeners. For HI listeners, the spatial separation was also advantageous in general, and their SSB was slightly greater in unfavorable listening conditions. However, the HI listeners hardly took advantage of the regular temporal dips of the modulated noise, even with the use of their hearing aids.Conclusion: NH listeners benefited from the fluctuation of the masker as well as the spatial separation between sound sources. A positive spatial separation benefit for HI listeners was only observed in an adverse listening condition. Regardless of the modulation rate, HI listeners received little benefit from glimpses of the target speech in the dips of the fluctuating masker. This result can be considered when planning audiological evaluation and rehabilitation for HI listeners.

Abstract:

Animal studies have revealed that moderate-level noise exposure can cause a permanent loss of ribbon synapses between inner hair cells and auditory-nerve fibers, but only temporary threshold shifts. Such noise-induced cochlear synaptopathy has been called ‘hidden hearing loss’ because while there is a significant degeneration of ribbon synapses, the resulting hearing dysfunction is effectively hidden from typical clinical assays. Here we used guinea pigs to study the mechanisms leading to hearing deficits resulting from a moderate noise. We measured distortion product otoacoustic emissions and auditory brainstem responses to assay peripheral hearing. We tested spatial hearing ability through the prepulse inhibition (PPI) of the acoustic startle reflex. PPI was used to measure hearing-in-noise ability, or spatial release from masking, as this task approximates the “cocktail party” effect. Finally, we performed immunohistochemistry to confirm synaptopathy. Results show that the noise exposure induces no permanent hearing threshold shift, but despite recovery of normal audibility, both behavioral and electrophysiological binaural hearing deficits persisted. Cochlear synaptopathy was objectively confirmed by visualizing the loss of ribbon synapses in the cochlea. The results demonstrate that cochlear synaptopathy causes deficits in brainstem circuits known to be critical for binaural and spatial hearing. [Work supported by Otolaryngology T32 DC012280.]

Abstract:

Background and Aims: In noisy listening environments, one of the skills that is critical for speech perception is spatial auditory processing. It is predicted that the spatial auditory processing ability of elderly people decreases due to structural and physiological changes in auditory cortex, central auditory pathways and peripheral auditory system. The aim of this study is to investigate dynamic spatial auditory processing in elderly with normal hearing. Materials and methods: This study was conducted on 35 people (16 men and 19 women) in the age range of 55 to 70 years with normal hearing and the results were compared with the results of 35 healthy people (15 men and 20 women) in the age range of 18 to 25 years. To investigate the dynamic spatial auditory processing, after performing preliminary examinations such as otoscopy, audiometry and tympanometry, the Persian version of speech perception, spatial hearing and quality of hearing questionnaire (SSQ) and the spatial hearing questionnaire (SHQ) were completed in the form of an interview. Then, the dynamic spatial quick speech in noise (DS-QSIN) and the binaural masking level difference (BMLD) test were performed using the relevant applications and the values of signal noise ratio (SNR) loss, SNR50 and MLD were recorded for each person. Results: There is a significant difference (P<0.05) between the elderly and young groups according to the results of the SSQ, SHQ questionnaire, the SNR50 and SNR loss index, and the value of MLD. In this study did not reveal a statistically significant difference between two genders (P>0.05). Conclusion: The findings of this study showed that despite normal hearing, dynamic spatial auditory processing in the elderly has a weaker performance than in young people.

Abstract:

Background: Deficits in spatial hearing can have a negative impact on listeners’ ability to orient in their environment and follow conversations in noisy backgrounds and may exacerbate the experience of hearing loss as a handicap. However, there are no good tools available for reliably capturing the spatial hearing abilities of listeners in complex acoustic environments containing multiple sounds of interest. Purpose: The purpose of this study was to explore a new method to measure auditory spatial analysis in a reverberant multitalker scenario. Research Design: This study was a descriptive case control study. Study Sample: Ten listeners with normal hearing (NH) aged 20–31 yr and 16 listeners with hearing impairment (HI) aged 52–85 yr participated in the study. The latter group had symmetrical sensorineural hearing losses with a four-frequency average hearing loss of 29.7 dB HL. Data Collection and Analysis: A large reverberant room was simulated using a loudspeaker array in an anechoic chamber. In this simulated room, 96 scenes comprising between one and six concurrent talkers at different locations were generated. Listeners were presented with 45-sec samples of each scene, and were required to count, locate, and identify the gender of all talkers, using a graphical user interface on an iPad. Performance was evaluated in terms of correctly counting the sources and accuracy in localizing their direction. Results: Listeners with NH were able to reliably analyze scenes with up to four simultaneous talkers, while most listeners with hearing loss demonstrated errors even with two talkers at a time. Localization performance decreased in both groups with increasing number of talkers and was significantly poorer in listeners with HI. Overall performance was significantly correlated with hearing loss. Conclusions: This new method appears to be useful for estimating spatial abilities in realistic multitalker scenes. The method is sensitive to the number of sources in the scene, and to effects of sensorineural hearing loss. Further work will be needed to compare this method to more traditional single-source localization tests.
