This study was designed to investigate the differences in hand preference and skilled hand movement between hearing impaired and non-hearing impaired children. The subjects were 78 hearing impaired (44 males, 34 females) and 68 normal hearing children (24 males, 44 females). Hand preference was measured through performance of ten tasks requiring hand use. Skilled hand movement was measured by a timed peg displacement task. The preference scores were classified as right and non-right hand preference and the skilled movement task was analyzed for speed of displacement of pegs for preferred and non-preferred hands. The hearing impaired subjects were significantly different from the normal controls in frequency of right hand preference with normal controls showing more frequent right handedness. The degree of deafness was not a significant factor in frequency of right preference in the hearing impaired group. On the peg displacement task, hand was significant, both the hearing impaired and normal control subjects were significantly faster with their right hands. Group approached significance. The unexpected result was that children with the greater degree of hearing loss performed better than those with less hearing impairment.

I would like to think that my poems only borrow life from my pen, taking on an identity and music of their own with the help of some ‘making’ on my part. My poems embrace a continuum of human experience from the intrapersonal to the societal. Using imagistic and cinematic forms, they preserve the vitality of their sources, from the music of cityscapes, to the texture of emotions, to the narratives of particular characters.

Full textAbstract:
An observational study was conducted examining the social and cognitive play of young children with hearing-impairment playing in small groups composed of both hearing and hearing-impaired peers. The questions addressed the effects of the hearing status of the play partner upon the social/cognitive play patterns of children with hearing-impairment, and the relationship between their play patterns and their communicative competence, social competence and speech intelligibility. Forty-eight hearing-impaired subjects ranging in age from 3-6 to 6-1 were observed playing with partners of same and different hearing status during integrated play sessions at 13 school sites. The social play categories included solitary, parallel and group play, while the cognitive play categories included functional, constructive and dramatic play. Results of the study showed that the play patterns of the hearing-impaired children differed significantly for each group of partners. When playing with hearing-impaired partners, subjects engaged in group functional and constructive play more frequently than parallel functional and constructive play, and with equal frequency in parallel dramatic and group dramatic play. When playing with hearing partners, subjects engaged with equal frequency in group and parallel play. When playing with mixed groups of hearing and hearing-impaired partners, subjects engaged in group dramatic play more frequently than parallel dramatic play, and with equal frequency in group functional and constructive play, and parallel functional and constructive play. Communicative competence was negatively correlated to functional play. A positive correlation was found between social competence and constructive play, and between speech intelligibility and dramatic play. These correlations remained significant when age was partialed out. The hearing-impaired subjects spent similar percentages of time in social/cognitive play as those reported for hearing children. The study supports the premise that the play of young hearing-impaired children varies according to the hearing status of the play partner and is neither delayed nor deficient.

Full textAbstract:
Magister Artium (Social Work) - MA(SW)Overwhelming evidence suggests that 90% of children with a hearing loss are born to hearing parents. Research indicates that often these hearing parents are ill-informed about the cause and type of hearing loss their child has, leading the hearing parents to feelings of grief and disempowerment. Many hearing parents at the time of the diagnosis experience emotional turmoil as the diagnosis is often unexpected, resulting in a plethora of questions asked. The research approach for the study was qualitative in nature as it set out to explore and describe the experiences of hearing parents of their child’s hearing loss. A phenomenological strategy of design was employed to capture the lived experience from the hearing parents. Data was collected by means of unstructured individual in-depth interviews with 11 hearing parents. Volunteer and snowball sampling were implemented so as to access hearing parents whose children had been diagnosed with hearing loss. Data was analysed according to Creswell (2007) and Klenke (2008) and the trustworthiness of the qualitative study was evaluated against the criteria that Guba described in Krefting (1991). Ethical considerations, such as voluntary participation, informed consent, confidentiality, anonymity, no harm done and debriefing, were adhered to. After the conclusion of the research analysis, the findings of the research were discussed and recommendations were made. The findings of the recommendations spoke to the better understanding of the emotions and challenges of hearing parents as well as putting forward suggestions for supportive coping mechanisms to be put in place to support hearing parents whose children have been diagnosed with a hearing loss.

Full textAbstract:
Childhood disability increases parental stress. Research on the laterality of childhood hearing loss or presence of a cochlear implant(s) as it relates to stress in hearing parents was limited before this study. The purpose of this quantitative study was to identify relationships between the independent variables of laterality (unilateral and bilateral) of a childhood hearing loss or presence of a cochlear implant(s) and the dependent variable of stress in hearing parents. Family systems theory provided a framework for viewing each member of the family as a part of a whole, whose life events, feelings, and actions affect all of the members of the family. For this study, hearing parents of children with a hearing loss living and receiving services in the state of South Carolina rated their personal stress levels by completing an anonymous Likert-scale questionnaire. Data were collected from 151 participants via an online hosting site and analyzed using factor analysis, descriptive statistics, and ANOVA procedures. Hearing parents of children with a cochlear implant(s) (n = 37) scored the highest on all measures of stress except those measuring communication stress. Hearing parents of children with a bilateral hearing loss (n = 56) scored highest on communication stress. Hearing parents of children with a unilateral hearing loss (n = 58) scored lowest on all measures. One of the largest contributing factors to parental stress was the differing opinions educators and medical providers. The findings of this study contribute to positive social change by providing insight into how a childhood hearing loss influences stress in hearing parents. This information may help educators, service providers, and families provide better resources to the family system.

McKenzie, Andrew Rayner. "An adaptive response hearing aid for high frequency hearing loss." Thesis, University of Southampton, 1988. https://eprints.soton.ac.uk/52267/.
Full textAbstract:
A new approach to the evaluation of hearing aid fitting has suggested that an adaptive frequency/gain characteristic is subjectively more beneficial for patients with precipitous high frequency hearing loss, listening to speech in the various quiet and noisy situations encountered in everyday life. The development and evaluation of such a hearing aid is described. Parameters for the operation of the adaptive response mechanism were determined experimentally by means of subjective listening tests using subjects with precipitous high frequency hearing loss. Software was compiled to implement these parameters on a specially designed, computer-controlled, master hearing aid system in real time. A novel evaluation procedure was developed in order to assess the benefits provided by this system in terms of objective speech discrimination measures and subjective judgements in simulations of real life listening conditions. Uncertainty about the effects of binaural hearing aid fitting and, in particular, the lack of scientific evidence of any subjective advantages to be gained, led to a secondary study of the benefits of fitting a preferred monaural response binaurally. The hypothesis that the adaptive frequency response hearing aid is more appropriate than a standard fixed frequency response aid for people with precipitous high frequency hearing loss, listening to speech in the variety of quiet and noisy situations encountered in everyday life, was partially upheld in that it was preferred by a significant number of patients with 4kHz hearing loss greater than, or equal to, 65 dBHL. However, for patients with less severe high frequency hearing loss, a flat frequency response was preferred. A secondary hypothesis, that binaural fitting of a person's preferred monaural hearing aid response provides further increases in benefit over those found for the monaural fitting, was upheld. Further findings with important implications for hearing aid fitting, both monaural and binaural, are discussed together with important directions for future work.

Full textAbstract:
The purpose of this study was to determine whether the career development process was the same for hearing-impaired and normally-hearing adolescents. Subjects included 71 deaf and 318 nonhandicapped adolescents and their parents. A literature-based causal model of career maturity (Model 1) was developed that was designed to explain career maturity in terms of background variables, family characteristics, and individual characteristics. The inclusion of these variables was based on family systems theory, social learning theory, and the empirical literature on the career maturity of nonhandicapped adolescents.
The regression of career maturity on the eight predictor variables in Model 1 explained about 20% of the variance in career maturity for the hearing group, and 28% for the deaf. Family cohesion was the strongest predictor of career maturity for both groups.
Despite several similar patterns of influence among the variables, a number of relationships among the variables differed for the two groups. Furthermore, differences were noted between the groups in terms of the total effects for some of the eight predictor variables such as age and achievement.
A second model was developed to describe the career development of the deaf. Model 2 included all of the variables in Model 1 as well as five additional variables specific to the experiences of the deaf. Model 2 explained 31% of the variance in the career maturity of the deaf subjects. The increase in variance explained was not great enough to be considered significant. The degree of the subject's hearing loss and the degree of mother-child communication were influential in describing the career development process for the deaf in Model 2.
The results suggest that there are similarities and differences in the development of career maturity for deaf and hearing adolescents. The process is more reliant upon background characteristics, such as age, for the hearing. For the deaf, family variables intervene to influence career maturity to a greater extent than for the hearing. For both groups, higher family cohesion scores were associated with greater career maturity. The inclusion of deaf-specific variables contributed to the explanatory power of the basic model, although not to a significant degree.Ph. D.

Questões silenciadas ao longo de décadas podem continuar a reverberar ainda hoje, atravessando gerações e experiências de vida distantes no tempo e no espaço. Anos de silêncio não são simplesmente um vazio, pois se acumulam quase imperceptivelmente. Como têm materialidade, embora extremamente sutil, eles afetam as pessoas que os herdam - seja por sorte, azar, acaso ou nascimento. Nesse sentido, esta tese de doutorado se inspira especialmente em uma fotografia na qual a artista japonesa Yamashiro Chikako aborda o legado da guerra em Okinawa, ilha no extremo sul do Japão. Para refletir sobre modos artísticos de escutar silêncios herdados, doze ensaios breves oscilam entre a pesquisa acadêmica e fragmentos de memória e de ficção. Os textos enfatizam sobretudo o potencial criativo da arte para sintonizar os aspectos sonoros, visuais e táteis do silêncio e lidar com o que não coube nos registros oficiais.
Unsettled issues silenced for decades may still resonate today, crossing generations and life experiences even when they are distant in time and space. Years of silence are not simply empty for they accumulate almost imperceptibly. Though extremely subtle, they have materiality, affecting those who inherited them - be it by sheer chance or birth. This dissertation takes inspiration from Japanese artist Yamashiro Chikako s work dealing with war legacy in Japan s southernmost island of Okinawa. These twelve short essays alternate between academic research and pieces of memory and fiction in order to reflect on artistic ways of hearing inherited silences. The texts highlight art s creative potential to perceive synesthetic aspects of silence (especially those related to hearing, sight, and touch), and its ability to cope with whatever was left outside official registers.

Thesis (MTech (Electrical Engineering))--Peninsula Technikon, Cape Town, 2000.This document gives a report on the research that has been done to simulate hearing loss. People working with the hearing impaired have no idea of what and/or how the hearing impaired person hears sound. An instrument that enables a normal hearing person to hear what a hearing impaired person hears, is referred to in this document as a Hearing Loss Simulator (HLS). An investigation of the feasibility and practicability of the abovementioned instrument, has led to the development of the HLS by making use of a distinct type of technology called Digital Signal Processing (DSP) technology. Before hearing loss can be simulated, the hearing loss first needs to be determined. A study of different procedures and methods for screening hearing has led to the incorporation of an existing instrument called an Audiometer. An audiometer is an instrument that determines the hearing loss by making use of pure tone sine waves. The results are then plotted on a graph called an Audiogram. The results of other methods that determine the hearing loss can also be transferred to the Audiogram. The Audiogram's information which is, in fact, the frequency response of the ear, is stored in a computer and is utilized to realize the HLS function. Six different DSP based methods were studied to shape any audio information according to a specific frequency response. The optimum method was identified and then implemented. The various methods are the following: Filter bank method Inverse Discrete Fourier Transforms (IDFT) method Inverse Fast Fourier Transforms (IFFT) method Chirp-z method Wavelet method Yule-walker method The ITFT method was identified as the optimum method and was therefore implemented. The algorithm to realize this method, was carried out by doing the IFFT calculation on computer and subsequently doing the filtering on a DSP processor called an ADSP-2181 processor. The audio information under investigation is fed into the instrument, it is then filtered according to the audiogram information and then sent out again. Any normal hearing person who wants to investigate the hearing impairment of the hearing impaired person can listen to sound reproduction through either a set of headphones or through a free field. This process is referred to in this dissertation as Hearing Loss Simulation.

The photographer discusses work in “Hearing Through Walls”, a Masters of Fine Arts thesis exhibit held at downtown Tipton Gallery from February 19th through March 2nd, 2018. The exhibition consists of 15 archival inkjet prints and one two-channel video piece, representing the artists three-year exploration into narrative forms in image making. Using non-traditional approaches to photographic portraiture and experimental exhibition layout, the artist forms questions around themes of domesticity, lost youth, and American masculinity. Among these themes is an investigation into photographic issues, including the cultural role that photographs play in perpetuating, miming, and disrupting the facades of everyday life. Non-photographic influences are listed, including the paintings of Edward Hopper and the filmmaking of Paul Thomas Anderson. Historic and contemporary photographic influences included are Garry Winogrand, William Eggleston, Philip-Lorca Dicorcia, and Katy Grannan.

Objective: This study investigated the perspectives of adults with hearing impairment on hearing help-seeking and rehabilitation. Design: Individual semi-structured interviews were completed. Study sample: In total, 34 adults with hearing impairment in four countries (Australia, Denmark, UK, and USA) participated. Participants had a range of experience with hearing help-seeking and rehabilitation, from never having sought help to being satisfied hearing-aid users. Results: Qualitative content analysis identified four main categories (perceiving my hearing impairment, seeking hearing help, using my hearing aids, and perspectives and knowledge) and, at the next level, 25 categories. This article reports on the densest categories: they are described, exemplified with interview quotes, and discussed. Conclusions: People largely described hearing help-seeking and rehabilitation in the context of their daily lives. Adults with hearing impairment rarely described clinical encounters towards hearing help-seeking and rehabilitation as a connected process. They portrayed interactions with clinicians as isolated events rather than chronologically-ordered steps relating to a common goal. Clinical implications of the findings are discussed.Funding Agencies|University of Queensland Graduate School||

Full textAbstract:
identity play an important role in how they communicate and interact with other individuals. One group in which identity construction and navigation is a difficult process is the hearing impaired population. In an effort to understand how these individuals construct their identity and navigate their hearing impairment, this study utilizes Communication Theory of Identity. Through the use of interactive interviews, the researcher was able to examine how 11 participants manage their identity as hearing impaired individuals. The interviews provided insight into the four layers of identity proposed by CTI – personal, relational, enacted, and communal – in the hearing impaired individual. The author discusses the themes within each of the four layers and the gaps present between the layers that emerged as the hearing impaired participants discussed how they navigate their hearing impairment. Furthermore, the implications of these themes and gaps within the hearing impaired individual’s identity, such as feeling disconnected from both the Deaf and hearing communities, are examined.

Full textAbstract:
Introduction: This study investigated hearing aid (HA) satisfaction among adult with hearing impairment (HI) in New Zealand. This study aimed to answer three questions: 1) What are the current HA satisfaction levels amongst adult HA users in New Zealand? 2) How do the satisfaction findings of this study compare with other HA satisfaction data? 3) What client factors are related to HA satisfaction?
Method: Participants were recruited prospectively. They completed a questionnaire prior to HA fitting and a questionnaire three months post-fitting. Information was collected on: age, gender, HA experience, HI severity, hearing ability, change in hearing ability, hearing handicap, communication self-efficacy, change in communication self-efficacy, HA self-efficacy, HA usage, and number of appointments. HA satisfaction was measured via the Satisfaction with Amplification in Daily Life questionnaire (SADL; Cox & Alexander, 1999).
Results: Data were collected for 47 participants. Of these, 91.5% fell within or above the normative range for global satisfaction established by Cox & Alexander (1999). The mean SADL scores were predominantly high compared to previous research. Satisfaction with negative features of HAs was especially high in this study. However satisfaction with the service and cost of HAs was low compared to other research. SADL scores were found to significantly relate to age, gender, change in hearing ability, hearing handicap, communication self-efficacy, change in communication self-efficacy, and HA self-efficacy.
Conclusions: Results differed from previous research indicating that HA satisfaction may differ over time and across countries. Assessing HA satisfaction in a comprehensive standardised way, as opposed to with a single-item measure, can help identify important related factors. Targeting identified variables such as communication and HA self-efficacy may lead to improved treatment efficacy.

Full textAbstract:
Small timing differences occur when sounds reach one ear before the other, creating interaural phase differences (IPDs). The phase-locked activity in the auditory nerve can, at low frequencies, preserve IPDs. IPDs are used for localising and separating sounds from different directions. Chapters 3, 5, and 6 report three studies of the independent effects of age and sensorineural hearing loss on the temporal processing of sound that aids spatial hearing. Chapters 2 and 4 describe two supporting methodological studies. Chapter 2 compared the duration of training required for stable IPD-discrimination thresholds for two stimulus presentation procedures. The procedure requiring the least training was adopted for subsequent studies. Age and hearing loss are related and both may affect sensitivity to IPDs. Chapter 3 demonstrated that hearing loss, regardless of listener age, is related to poorer sensitivity to IPDs in the temporal fine structure (TFS), but not in the temporal envelope. Chapter 3 also showed that age, independent of hearing loss, is related to poorer envelope-IPD sensitivity at low modulation rates, and somewhat poorer TFS-IPD sensitivity. In Chapter 5, listener age and IPD sensitivity were both compared to subcortical neural phase locking measured through the frequency-following response (FFR). Phase coherence in the envelope-FFR at 145 Hz modulation and in the TFS-FFR deteriorated with age, suggesting less precise phase locking in old age. However, age-related changes to IPD sensitivity were not strongly related to age-related changes in FFR phase coherence. IPD sensitivity declines may be predominantly caused by deterioration of binaural processing independent of subcortical phase locking. Chapter 4 showed that electrodes at the mastoids recorded TFS-FFR generated earlier in the auditory pathway than electrodes from the nape of the neck to forehead, which recorded FFR generated later in the brainstem. However, these electrode montages did not reveal different age- or hearing-loss-related FFR deficits in Chapter 5. Chapter 6 determined whether hearing loss affected the ability to use TFS IPDs to achieve better speech perception. On average, old hearing-impaired listeners gained a small, but significant, benefit from a lateral separation of the speech sources. Replacing the TFS with binaurally in-phase sine waves (removing the TFS IPDs) significantly reduced the benefit of lateral separation. How much a listener benefitted from intact TFS IPDs in speech perception was strongly related to the extent of their hearing loss at low frequencies and their monaural processing of TFS, but not to their ability to discriminate IPDs. In general, this thesis shows that low-frequency hearing loss is associated with poor sensitivity to TFS IPDs and the ability to benefit from them when sounds are laterally separated. The thesis also shows that old age can reduce sensitivity to IPDs and weaken subcortical temporal coding. Although only partly related, these effects are likely to cause problems for old individuals in challenging listening environments.

Full textAbstract:
Although hearing loss is among the most common chronic conditions in the U.S., many individuals never speak to a healthcare provider about it. Thus, evaluation and rehabilitation services remain underutilized. Even mild hearing loss may result in decreased quality of life, social isolation, and decreased selfsufficiency. The purpose of this study was to assess factors that influence hearing healthcare access and hearing aid acquisition by individuals in Southern Appalachia. The identification of barriers to hearing healthcare access may help audiologists tailor care to this group‘s specific needs. The Hearing Handicap Inventory for Adults (HHIA), a questionnaire assessing self-perceived hearing handicap (a major determinant in help-seeking behaviors in people with hearing loss), was administered along with a researcher-designed survey. The researcher-designed survey was comprised of two forms. Form A asked questions specific to unaided individuals, with half pertaining to individuals with normal hearing, and the other half pertaining to individuals with unaided hearing loss. Form B asked questions specific to hearing aid users. Both forms collected demographic information. Survey participants were recruited from the Remote Area Medical (RAM) clinic held in Bristol, TN on May 1-3, 2015. HHIAs and surveys were obtained from 127 individuals. Two major barriers to hearing healthcare were identified: financial barriers and transportation-related barriers. 62% of respondents reported a household income of $20,000 or less, with an average household size of 2.6 members. Because hearing aids must often be purchased out of pocket, individuals in this income bracket may not be able to afford assistive devices. Some individuals in Southern Appalachia live far from the urban centers where audiologists tend to be located. Although the unaided individuals surveyed indicated they could travel some distance for hearing healthcare services, more than half indicated that they would be unable to travel more than an hour. In contrast, more than half of the aided group indicated that they were required to travel more than an hour for services. Since rural areas often lack public transportation, costs associated with traveling a long distance using personal transportation may present a barrier to hearing healthcare access. These barriers may be at least partially remediated by financial aid programs, telehealth services, and self-help/support group initiatives. The Bristol RAM clinic, in partnership with ETSU‘s audiology department, attempts to overcome these barriers by providing free hearing screenings and low-cost amplification options to individuals with hearing loss living in rural areas.

Listeners with sensorineural hearing loss are often impaired in their ability to perceive the pitch associated with the fundamental frequency (FO) of complex harmonic sounds. Four studies investigated the relationship between FO discrimination performance and the ability to resolve individual harmonic frequencies of a complex, testing the hypotheses (1) that the accurate FO discrimination performance associated with low-order harmonics is due to their being resolved, and (2) that listeners with sensorineural hearing loss experience a pitch discrimination deficit due to a reduction in frequency selectivity. The first study revealed that resolved harmonics were not sufficient for accurate FO discrimination. Increasing harmonic resolvability by presenting even and odd harmonics to opposite ears did not improve pitch discrimination, raising the possibility that complex-tone pitch discrimination is not governed by harmonic resolvability per se, but is related to harmonic number. Based on this idea, the second study found that an autocorrelation model of pitch perception, modified to include place dependence by limiting the range of periodicities accurately processed by a given frequency channel, could account for the more accurate FO discrimination associated with low-order harmonics without relying on harmonic resolvability.
(cont.) However, further results in the third and fourth studies suggested a role for harmonic resolvability in pitch discrimination, inconsistent with the lack of dependence on resolvability of the modified autocorrelation model. In normal-hearing subjects at high stimulus levels and in hearing-impaired subjects, a wider spacing between adjacent frequency components, related to a reduction in frequency selectivity, was required to yield accurate FO discrimination performance. Thus, resolved harmonics may be necessary for accurate FO encoding, and the pitch discrimination deficit associated with sensorineural hearing loss may be related to a reduction in frequency selectivity. These results support spectral or spectrotemporal pitch models that derive FO from resolved harmonics, or a place-dependent temporal model whereby peripheral filter bandwidths limit the range of detectable periodicities. Because spectral processing plays an important role in pitch discrimination, hearing-impaired and cochlear-implant listeners may benefit from hearing-aid fitting procedures and cochlear-implant processing algorithms that emphasize or enhance spectral place cues.

Full textAbstract:
This phenomenological study investigated the nature and extent of the support parents received during IEP development. The study was informed by Bronfenbrenner's ecological systems theory. Participants, located in a Northeastern state, were 10 hearing parents of children who had been diagnosed with hearing loss at birth and were between ages 5 and 12. Data were in-depth interviews that were analyzed, coded, and organized into themes using an inductive approach to analysis informed by Hatch. Results indicated that parents believed they needed more guidance on what to expect during the first IEP meeting, that advocating for appropriate accommodations for their child was important, and that education professionals communicate in a more compassionate and less business-like manner when speaking with parents. Parents also indicated increased anxiety due to their perceptions that education professionals have inadequate knowledge about issues relating to hearing loss and hearing amplification technology. Based on these results, special education professionals and policy makers can focus on increased understanding of hearing loss and amplification use in order to help children with hearing loss achieve more positive educational outcomes effecting positive social change.

Full textAbstract:
This thesis is a document which tells a story of a narrative inquiry into DEAF-HEARING family life. The story involves me and a group of people who have, for the past four years, taught me about their lives growing up, living with DEAF and HEARING parents, children, siblings, cousins, aunts, uncles, grandparents, great-grandparents, step-relations, and negotiating DEAF and HEARING worlds. The inquiry was embarked on as a political counter-narrative to common mainstream assumptions on, and hegemonic discourses of, deafness, of family-life experience, of sign language and of DEAF lives. In doing so, spaces were created that respect human beings, adults, children, DEAF and HEARING, as storytelling beings and recognise narratives as political and performative resistance to oppression, marginalisation and ignorance. With a grounding in Deafhood and Deaf Theory and a culturally sensitive methodology which acknowledges appropriate ways of collaborating with participants as equal, agentic and creative, this inquiry re-presents stories of DEAF-HEARING family life as resistance narratives. Deafhood addresses the power of discursive systems in which DEAF people are viewed as broken, in need of cure and normalisation and draws parallels with post-colonial theory and minority cultural studies in order to counter the dismissal of DEAF lives as lacking, impoverished and pitiable. Deafhood also celebrates DEAF people’s cultural strategies of collective, political resistance and demand for equality in light of the never-ending medical campaign to eliminate deafness. Deaf Theory casts a philosophical lens over the DEAF body to acknowledge sign languages as textual, and the DEAF person as a visual, tactile being, with an alternative sensory orientation to the world. Narrative inquiry opens up dynamic spaces for people to tell stories and to construct meanings woven from their biographies, histories and cultures. A narrative inquiry with DEAF-HEARING families, infused with ideas and philosophies of Deafhood and Deaf Theory, as well as from postmodern/poststructural feminist theory, draws together the threads of DEAF histories and family lives, and makes way for a space in which narratives of DEAF and HEARING people who live/have lived together and are committed through blood and/or relationships of care, love, affection and cultural transmission, can be told, re-told, recorded, crafted and re-presented, to other families, to DEAF communities and to those authorities and organisations who concern themselves with the welfare and well-being of DEAF and HEARING adults and children. The narratives at the heart of this thesis reveal not only the ways in which damaging and hurtful definitions of, and discrimination towards, DEAF people and signing families is troubled, destabilised and resisted, but also how pride in, and celebration of, DEAF lives and sign language are affirming and essential for family life, together with the desire for this intimate, cultural and political re-visioning of DEAF/DEAF-HEARING life to be properly heard.

Full textAbstract:
The long-term outcomes of subjects fitted with a bone anchored hearing aid (BAHA) for a unilateral profound sensorineural hearing loss (UPSHL) are still evolving. Previous studies have focused on the comparison between shortterm outcomes obtained with hard-wired contralateral routing of signal (CROS) hearing aids and those obtained with BAHA devices. Published results on subjects who have worn their BAHA devices for UPSHL for more than twelve months are limited. This study explored the long-term outcomes of adults fitted with a BAHA for UPSHL. The aims were firstly to examine subjects' pre-operative and postoperative speech perception in quiet and noise, as well as administer two standardised questionnaires, the Abbreviated Profile of Hearing Benefit (APHAB) and the Glasgow Hearing Aid Benefit Profile (GHABP). The second aim was to evaluate the responses of implanted subjects following the preoperative test protocols using a supplementary questionnaire, the Single Sided Deafness Questionnaire (SSDQ). The third aim was to monitor the subjects' implant or repair issues. In addition, questionnaire results were compared to subjects who underwent pre-operative assessment but were not implanted. All subjects had a UPSHL resulting from various aetiologies including vestibular schwannoma or other skull base tumour removal, viral infections, cochlear trauma, idiopathic sudden hearing loss, and Meniere's disease. There was a significant difference between the implanted groups' pre- and post-operative outcomes measures, indicating a treatment effect from the fitting of the BAHA device. No significant changes were found with the non-implanted groups' longterm outcome measures in regards to their perceived hearing difficulties. No significant correlations were found between outcome measures and gender, age of fitting, length of deafness, or ear affected for either group.

Full textAbstract:
A common cause of profound deafness is hair cell dysfunction in the cochlea. Cochlear implants (CI) bypass the hair cells via an electrode and stimulate the cochlear nerve directly. Nowadays, it is possible to preserve residual hair cell function and hearing through flexible electrodes and a-traumatic CI surgery techniques; called hearing preservation CI surgery. This may suit partially deaf patients who can use natural low frequency hearing in combination with electric high frequency hearing; so-called hybrid hearing. The aim of this thesis was to elucidate the effectiveness of hearing preservation CI surgery. The thesis demonstrates human cochlear anatomy in relation to CI and evaluates hearing and patient satisfaction after hearing preservation CI surgery. Analyses of human cochlear moulds belonging to the Uppsala collection showed large variations in dimensions and coiling characteristics of the cochlea. Each cochlea was individually shaped. The size and shape of the cochlea influences the position of the electrode. The diameter of the basal cochlear turn could predict insertion depth of the electrode, which is crucial for hearing preservation. The first 21 patients operated with hearing preservation CI surgery in Uppsala, showed preserved hearing. Nine-teen partially deaf patients receiving implants intended for hybrid hearing, were evaluated concerning pure tone audiometry, monosyllables (MS) and hearing in noise test (HINT). They also responded to a questionnaire, consisting of the IOI-HA, EQ-5D VAS and nine questions about residual hearing. The questionnaire results indicated a high degree of patient satisfaction with improved speech perception in silence and noise. This was also reflected by improved results in MS and HINT. Hearing was preserved in all patients, but there was an on-going deterioration of the residual hearing in the operated ear which surpassed the contralateral ear. There were no correlations between the amount of residual hearing and patient satisfaction or speech perception results. Electric stimulation provides a major contribution to speech comprehension in partially deaf patients. All the patients showed a high degree of satisfaction with their CI, regardless of varying hearing preservation.

Full textAbstract:
Philosophiae Doctor - PhDParenting children with a hearing loss presents hearing parents with unique parenting challenges. Adapting to and managing these challenges is dependent on parents’ personal and social support as well as the resources available to them. There is limited research regarding hearing parents’ personal and social support and access to appropriate resources. In order to bridge this gap, the aim of the study was to develop guidelines for hearing parents parenting children with a hearing loss. A mixed methods approach with a sequential explanatory design using a two-phased approach was employed in this study. Phase 1 endeavoured to identify the problem and explore the needs of parents by using a staged approach. The sample in this phase included 103 participants in the quantitative study and 13 participants in the qualitative study. Phase 2 applied a consensus workshop made up of two rounds: Round 1 comprised a panel of experts, namely, academics in the field of child, family, and disability studies, and Round 2 included a panel of stakeholders comprised of hearing parents, professionals, Deaf mentors, and leaders working within the field of hearing loss. The purpose of the workshop was to reach consensus on the development of guidelines. From this research, a number of guidelines emerged for parents, focusing on:1) early intervention programmes for hearing parents and children diagnosed with a hearing loss, highlighting guidance and counselling for parents on early identification and screening programmes; 2) the need for social and emotional support to deal with the emotional impact of the diagnosis on the family, the parents, as well as the child with a hearing loss; 3) access to resources and information which is comprehensive and unbiased, allowing parents to make informed choices; and 4) support for communication intervention whereby parents are offered unbiased support in terms of communication options for their children. This study has important implications for the collaboration and partnerships between parents, social services (social workers), and health and family practitioners for the provision of family-centred practices.

Full textAbstract:
Otoacoustic emissions (OAEs) are generated in the cochlea in response to sound and are used clinically to separate ears with normal hearing from sensorineural hearing loss (SNHL). OAEs were elicited at ambient pressure by clicks (CEOAE) and wideband chirps (TEOAE) sweeping from low-to-high frequency with a sweep rate of either 187.6 Hz/ms (short chirps) or 58.2 Hz/ms (long chirps) and a bandwidth extending to 8 kHz. Chirps were presented at the same sound exposure level (SEL) as clicks, or + 6 dB relative to clicks. A total of 288 OAE waveforms were averaged for short chirps in ~1 minute compared to 120 waveforms for long chirps. Compared to clicks, the chirp has a lower crest factor, which allows it to be presented at an overall higher SEL without distortion. OAEs were elicited in 79 adults with normal hearing and 51 adults with mild-to-moderate SNHL. One-sixth octave OAE signal-to-noise ratios from 0.7 to 8.0 kHz were compared across stimulus types and conditions. The area under the receiver operating curve (AUC) was used to assess the accuracy of detecting SNHL. Average AUCs across 1/6th octave frequencies ranged from 0.90 to 0.89 for TEOAEs and were 0.87 for the CEOAE suggesting excellent test performance.

Full textAbstract:
Cortical auditory evoked potentials (CAEPs) are currently being investigated as a tool for validation in hearing aid fittings. There is some conflicting evidence regarding the usefulness of CAEPs in this capacity. CAEPs are influenced by stimulus parameters and hearing aids can change these parameters in an unpredictable manner. The purpose of this study was to investigate the effect of rise time after hearing aid processing on the CAEP of 23 normal hearing participants. Two different duration stimuli (60 ms and 120 ms) were processed by three different hearing aids and the output of each hearing aid was recorded. The stimulus parameters were measured for each condition and the stimuli were presented to each participant through an insert earphone. Two blocks of stimuli were used (1) Raw (varied SNR and intensity) and (2) Equalized/Filtered (equalized SNR and intensity). The electroencephalography (EEG) was recorded and the P1-N1-P2 amplitudes and latencies were measured for each condition. A three-factor ANOVA was conducted to observe the effects of (1) rise time, (2) duration, and (3) SNR. A main effect of rise time was observed on the N1-P2 amplitude. This result indicated that hearing aid processing can increase the rise time enough to elicit a decrease in the N1-P2 amplitude. No effects were observed on amplitudes or latencies of the N1-P2 with the alternative stimulus parameters (SNR and duration). Prior to using CAEPs clinically for validation of hearing aid fittings, normative standards should be established. This ensures that differences in the N1-P2 amplitudes are due specifically to audibility and not to the altered stimulus parameter (i.e., after hearing aid processing). Further research should also be conducted on individuals with hearing loss to see if the effects observed in this study would be present with this population. In addition, comparisons of behavioural and CAEP methods of validation would be helpful in determining the validity and reliability of using these methods clinically.Medicine, Faculty of
