Abstract:

Research on soundscape explore facets of how acoustic environments affect human perception in context. By means of psychoacoustic parameters the sound character of acoustic environments can be described comprehensively as those parameters play an important role with respect to manifold auditory sensations. Although there seems to be a consensus of the benefit of psychoacoustics for soundscape evaluations and the ISO/TS 12913-2 particularly requests to give consideration to psychoacoustic indicators in soundscape investigations rather little is known about the relationships between psychoacoustic quantities and significant soundscape dimensions. Numerous investigations aimed to establish links between psychoacoustics and soundscape appraisal, but the gained results were often not suited for generalization. Moreover, it is rather unclear how urban locations vary in their sound character over longer periods and how the level of variation drives soundscape assessments. In order to establish an understanding of potential psychoacoustic characterization of urban locations for soundscape evaluations, repeated measurements of different locations are analyzed and the general behavior of psychoacoustic quantities derived. Based on these investigations it is intended to expand knowledge on the usefulness of psychoacoustics from the perspective of the soundscape approach.

Abstract:

The field of acoustics encompasses the examination of sound, encompassing both its physical characteristics and the way in which humans perceive auditory input. Acoustics is the study of how sound waves are created and spread physically, while psychoacoustics connects these physical characteristics to our auditory perceptions. Comprehending these two features is essential for progress in audio technology and understanding auditory perception aberrations such as paracusia and diplacusis. This research consolidates information from multiple investigations to examine the interaction between acoustics and psychoacoustics. The technique entails examining the current body of literature on the fundamental principles governing sound waves, their interaction with various materials, and their movement across space. The examination of psychoacoustic elements involved the conversion of sound waves into brain impulses. The study also examines certain psychoacoustic phenomena, such as the sense of pitch and auditory distortions. By combining acoustic and psychoacoustic concepts, we can gain a thorough comprehension of how we perceive sound. Sound waves, generated by mechanical vibrations, pass through substances such as air, causing compression and rarefaction cycles that move at a speed of about 344 m/s at a temperature of 20°C. Psychoacoustics studies the perception of sound waves, specifically how they are processed by the ear and converted into neural signals that the brain can understand. The key findings reveal the subjective nature of pitch perception, where alterations in intensity or length impact the perceived frequency and the precise sensitivity of pitch discrimination. Furthermore, abnormalities such as paracusia and diplacusis emphasize the intricacies of auditory perception. The study highlights the significance of psychoacoustics in audio technology, where principles are utilized in audio compression and noise reduction to improve sound quality and clarity. The comprehensive comprehension of acoustics and psychoacoustics lays the groundwork for advancements in audio technology and the creation of auditory experiences.

Abstract:

Vacuum cleaners are one of the most widely used household appliances associated with unpleasant noises. Previous studies have indicated the severity of loud vacuum cleaner noise and its impact on the users nearby. The standalone quantified measurements of the generated noise are not sufficient for properly characterizing vacuum cleaners. Human perception should also be included for a better assessment of the quality of sound. A hybrid approach such as psychoacoustics analysis, which comprises subjective and objective evaluations of sounds, has recently been widely used. This paper focuses on the experimental assessment of vacuum cleaner noise and evaluates their psychoacoustical matrices. Three vacuum cleaners with different specifications have been selected as test candidates, and their sound qualities have been analyzed. Statistical analysis, ANOVA, has been performed in order to investigate the effectiveness of individual psychoacoustic metrics.

Abstract:

Dave Green’s career spanned four decades all devoted to the study of psychoacoustics. It is hard to imagine anyone whose work has had a greater impact on the field. Dave’s interest in psychoacoustics began as an Experimental Psychology student at the University of Michigan. He is most widely recognized in the field of psychophysics for his pioneering contributions to Signal Detection Theory (SDT), which he helped develop in the Electronic Defense Group (EDG) of the Department of Electrical Engineering in the early 1950s. The culmination of this work is given in his seminal text “Signal Detection Theory and Psychophysics” (co-authored with John Swets) in 1966. His later work on Profile Analysis in the 1980s helped established a new view of auditory perception. As a consultant for Bolt, Beranek, and Newman (BB&N), Dave provided numerous publications and reports that have served beneficial to society, including his testimony regarding the reenactment of the assassination of John F. Kennedy in 1979. More than 50 students, post-docs, and colleagues, many who have made important contributions to psychoacoustics, have worked directly in Dave’s labs and received his mentoring. To say that Dave Green is a psychoacoustic icon would be an understatement.

Abstract:

Aeroacoustic noise in multiple rotor drones has been increasingly recognized as a crucial issue, while noise reduction is normally associated with a trade-off between aerodynamic performance and sound suppression as well as sound quality improvement. Here, we propose an integrated methodology to evaluate both aeroacoustics and psychoacoustics of a single propeller. For a loop-type propeller, an experimental investigation was conducted in association with its aerodynamic and acoustic characteristics via a hover stand test in an anechoic chamber; the psychoacoustic performance was then examined with psychoacoustic annoyance models to evaluate five psychoacoustic metrics comprising loudness, fluctuation strength, roughness, sharpness, and tonality. A comparison of the figure of merit (FM), the overall sound pressure level (OASPL) and psychoacoustic metrics was undertaken among a two-blade propeller, a four-blade propeller, the loop-type propeller, a wide chord loop-type propeller, and a DJI Phantom III propeller, indicating that the loop-type propeller enables a remarkable reduction in OASPL and a noticeable improvement in sound quality while achieving comparable aerodynamic performance. Furthermore, the psychoacoustic analysis demonstrates that the loop-type propeller can improve the psychological response to various noises in terms of the higher-level broadband and lower-level tonal noise components. It is thus verified that the integrated evaluation methodology of aeroacoustics and psychoacoustics can be a useful tool in the design of low-noise propellers in association with multirotor drones.

Abstract:

Abstract Psychoacoustics is traditionally based on a world model that assumes a physical world existing independently of any observer - the so-called objective world. Being exposed to this world, an observer is impinged upon by a variety of stimuli reaching his/her sensory organs. These stimuli, if physiologically adequate, may cause biological transduction and signal processing in the sensory organs and its afferent pathways in such a way that finally a specific excitation of the cortex takes place, which results in sen-sations to appear in the observer’s perceptual world. The sensations are understood as being subjective, since they require an observer to exist. This world model - also known as (objectivistic) realism - reaches its limits when it comes to explaining more complex phenomena of perception. Thereupon, in this paper, an alternative world model is emphasized and applied to psychoacoustics, namely the perceptionist’s model. Like realism, perceptionism has a long tradition in epistemology. It appears to be suitable to improve our understanding of perceptual organization.

Abstract:

Road traffic noise is well accepted to be one of the significant sources of environmental noise. The traditional norms of noise evaluation are mainly focused on the noise level and the loudness sensation of occupants. However, researchers found that human perceptions of sounds are multidimensional psychological processes in the perceptual dimensions about the human general judgment (Evaluation, E), sensitivity to the magnitude (Potency, P), and sensation of the temporal and spectral compositions (Activity, A) of noise. After that, a valid, reliable, and applicable psychometric tool called Psychoacoustics Perception Scale (PPS) is designed to assess the multidimensional perceptual responses of occupants in the environment. This study aimed to investigate the performance of the psychoacoustic metrics and the PPS in evaluating the objective characterizes and the subjective perceptual influence of road traffic noise on occupants, respectively. The results of the study showed that the gradings of the noise obtained from the PPS were associated with changes of the objective characterizes of the road traffic noise. These findings provided knowledge on the development of multidimensional psychoacoustic grading method for road traffic noise in future.

Abstract:

Noise in eating establishments has been studied in architectural acoustics literature. For evaluating acoustics in these spaces, researchers predominantly investigate sound pressure levels and reverberation times. Yet, noise in eating spaces originate from a wide variety of sources and is hard to describe and evaluate with only sound pressure levels and reverberation times. Better metrics for acoustics in closed public spaces are needed. Psychoacoustic parameters of loudness, sharpness, fluctuation strength and roughness are promising metrics that have been used by many recent studies evaluating noise annoyance. However, unlike the established metrics such as reverberation time, no set of recommended values exist for these parameters, yet. The aim of this study is to investigate noise in eating establishments through psychoacoustic parameters and understand both the noise characteristics and the metrics themselves. This paper presents a set of sound recordings during lunch hours in two eating spaces in Izmir Institute of Technology. The entry and egress of occupants have been tracked manually, while sound levels have been measured and the noise has been recorded for psychoacoustics analysis. The relationship between the number of occupants and psychoacoustic parameters has been investigated through these objective measurements. The relationship between the number of occupants and sound levels is discussed in the light of the Lombard effect.

Abstract:

The cocktail party problem was first coined by E Colin Cherry in 1953 and it describes the archetypal challenge of listening in a complex soundscape (e.g., multiple talkers conversing vying for your attention in a crowded restaurant). In the past two decades, the field of psychoacoustics has steadily marched towards understanding how we listen in these naturalistic environments. Many studies have focused on studying the psychological and physiological aspects of auditory scene analysis and object-based attention as well as how these processes differ in typical listeners from others with listening difficulties. In recent years, there has also been a burgeoning interest in understanding how cognitive load and listening effort affect our ease of listening in different situational contexts (e.g., talking while driving). In this talk, a brief survey of modern psychoacoustic experimental approaches will be presented in the hope to spur new collaborative research ideas with those who study soundscape.

Abstract:

In this paper the ingredients of computing auditory perception are reviewed. On the basic level there is neurophysiology, which is abstracted to artificial neural nets (ANNs) and enhanced by statistics to machine learning. There are high-level cognitive models derived from psychoacoustics (especially Gestalt principles). The gap between neuroscience and psychoacoustics has to be filled by numerics, statistics and heuristics. Computerised auditory models have a broad and diverse range of applications: hearing aids and implants, compression in audio codices, automated music analysis, music composition, interactive music installations, and information retrieval from large databases of music samples.

Abstract:

Within the joint project "Real-time Calculation, Auralization and Visualization of Sound Propagation and Noise Protection Measures for Infrastructure Projects" (EAV-Infra), funded by the Federal Ministry for Economic Affairs, the potentials of digital infrastructure planning based on Building Information Modelling (BIM) and the auralization of different states of planning will be combined. In this contribution, the objectives of the project will be presented with particular focus on the intended application of psychoacoustics. Currently, planning noise protection measures encompasses an elaborate comparison of various planning alternatives in a time-consuming process. Sound pressure levels, which are only informative to experts, are used to communicate states of planning to the public. Auralized signals of noise immissions and a description of the effectiveness of noise protection measures by hearing-oriented quantities could constitute a more intuitive and intelligible evaluation basis for project managers and residents alike. In EAV-Infra, noise exposure will be evaluated based on psychoacoustic quantities. Both classical quantities and newly developed indices, will be considered. In order to find a suitable psychoacoustic annoyance model for the railway context, listening experiments will be conducted, in which subjects evaluate various noise situations. Typical inner- and outer-city scenarios and various noise protection measures will be assessed.

Abstract:

The perception of dynamic – constantly changing – pitch in speech has been extensively studied in psychoacoustics and linguistics. In psychoacoustic studies, listeners are usually presented with short stimuli such as vowels or syllables, and their ability to discriminate a pair of stimuli is assessed. On the other hand, linguistic studies concern intonation over an utterance. Intonation entails not only acoustic prominence realised by pitch, duration, and loudness, but also listeners’ knowledge about the relative prominence between syllables or between words in their language. This paper discusses a series of speech perception experiments using both psychoacoustic and linguistic tasks. Participants judged either relative pitch height or prominence between two pitch peaks or valleys in an utterance. Native English speakers in different age and dialectal groups were tested. The results showed that, first, listeners’ pitch height discrimination in the utterance context seems to be more accurate than previously reported. Second, there is a robust perceptual asymmetry between pitch peaks and valleys, the valleys posing significant challenges in perception. Third, listeners’ perception of pitch height and prominence is disassociated. The findings taken together suggest an intricate interaction between the physical properties of the stimuli and listeners’ top-down knowledge in the perception of speech intonation.

Abstract:

It is known that an air-conditioning system is an essential component of modern buildings for maintaining good indoor environmental quality. However, the adverse effect due to air-conditioned noise can offset its benefits. Although several noise indices such as Noise Criteria (NC), Noise Rating (NR), Room Criteria (RC), and A-weighted equivalent continuous sound pressure level (LAeq) have been developed to assess the acceptability of indoor noise environments, the noise feature of the environments and its psychological impacts on the occupants are not comprehensively evaluated. Psychoacoustics Perception Scale (PPS) is a psychometric tool to assess the psychological impacts about general judgment (Evaluation, E), sensitivity to the magnitude (Potency, P), and sensation of the temporal and spectral compositions (Activity, A) of noise on occupants. This study aimed to evaluate the air-conditioning building environments by using the traditional noise indices, psychoacoustic metrics, and the PPS. The significant correlations were found between the objective and subjective data. The results of the study provided the useful knowledge on future designs of the environmental controls of air-conditioned noise.

Abstract:

Psychoacoustics is considered to be a category of psychophysics and is termed as the assessment of auditory or sound perception and deals with perception of sound among different human beings. Psychoacoustics is a very qualitative phenomenon and is often the reason for an individual to perceive the sound in different manner, as compared to another. This effect is more prominent in music wherein a given music bit may seem good to one, whereas, another may perceive it as bad. For this to happen, various attributes of sound play an important part, in the categorization based on psychoacoustical perception. The present work considered pitch as the varying attribute and provided a comparative assessment of sound, based on the variation of pitch in terms of Pitch Detection Threshold (PDTh) between trained musicians and non-musicians. 44 subjects of both conditioned and controlled set were considered for this study and were made to undergo the Pitch Detection Test (PDT) to assess their PDTh. Two trials were conducted, once in the morning and the other in the evening. The results provided substantial cue to conclude that the musicians had a better PDTh (6.83 dB) than the control set (31.31 dB). Also, the PDTh was better in the morning trials, as compared to their evening counterparts. This could be attributed to the professional training in music, due to which the conditioned set outperformed the control set of subjects. Such an analysis could aid in the assessment of auditory perceptive abilities and their improvement with music and hence indicate the plausible improvement in the auditory perception with music based raaga therapy. Further, more attributes such as intensity and frequency could be encompassed to provide stronger relationship between perception and learning, in this case being music training sessions, which could also work as therapy for certain auditory perceptive disorders.
