Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Available in PDF, EPUB and Kindle. Book excerpt: The Auditory Brain and Age-Related Hearing Impairment provides an overview of the interaction between age-related hearing impairments and cognitive brain function. This monograph elucidates the techniques used in the connectome and other brain-network studies based on electrophysiological methods. Discussions of the manifestations of age-related hearing impairment, the causes of degradation of sound processing, compensatory changes in the human brain, and rehabilitation and intervention are included. There is currently a surge in content on aging and hearing loss, the benefits of hearing aids and implants, and the correlation between hearing loss, cognitive decline and early onset of dementia. Given the changing demographics, treatment of age-related hearing impairment need not just be bottom-up (i.e., by amplification and/or cochlear implantation), but also top-down by addressing the impact of the changing brain on communication. The role of age-related capacity for audio-visual integration and its role in assisting treatment have only recently been investigated, thus this area needs more attention.

Available in PDF, EPUB and Kindle. Book excerpt: Speech-in-noise tests are an important tool for assessing the speech recognition ability of a listener. While several well-established clinical measurement procedures exist, most come with the drawback of a high measurement effort, since a specialist needs to conduct the speech audiometric test. This work addresses this issue by proposing self-measurement applications utilizing automatic speech recognition (ASR). Two different application scenarios are considered: a well-controlled laboratory environment with a locally running ASR system developed specifically for this purpose and a screening application using the ASR component of a smart speaker - i.e., a commercially available high-quality speaker connected to a virtual assistant. The two systems proposed are evaluated with 139 subjects in total - covering a wide range of hearing abilities: normal-hearing listeners, mildly-, moderately- and severely hearing-impaired subjects, as well as listeners with cochlear implants. The measurement accuracy with the unsupervised procedure was found to be in the same range as when conducting the test with a human supervisor.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Individuals with {it sensorineural hearing loss} (SNHL) are prescribed hearing aids and/or a cochlear implant, based on their pure-tone threshold and speech perception scores. Although these assistive listening devices do help these individuals communicate in quiet surroundings, many still have difficulty understanding speech in noisy environments. Especially, listeners with mild-to-moderate SNHL have complained that their hearing aids do not provide enough benefit to facilitate understanding of normal speech. Why is it that the modern hearing aid, even with a high level of technology, does not produce one-hundred percent efficiency? We shall show that the current clinical measurements, which interpret the result as a mean score (e.g., pure-tone average, speech recognition threshold, AI-gram, etc.), do not deliver sufficient information about the characteristics of a SNHL listener's impairment when hearing speech, and thus, result in a poorly fitting hearing aid.\ This dissertation addressed three key questions, fundamental to clinical audiology and hearing science: (1) How well do the results of standard clinical tests predict the speech perception ability of SNHL patients? (2) Are the existing methods of hearing aid fitting (e.g., the half-gain rule, NAL-R, etc.) appropriate for modern hearing aid technology? (3) How useful are measured error patterns of speech perception in SNHL patients in addressing these perception errors?\ Four sub-studies were conducted for finding answers to the proposed questions: textbf{Study I} measured individual consonant errors to quantify how each hearing-impaired (HI) listener perceives speech sounds (e.g., high- vs. low-error consonants), and then compared the individual consonant errors to the results provided by currently used clinical measurements to ascertain the differences. The results of Study I showed that the HI ear had significant errors in receiving only a few consonants. There was a low correlation between the error rates of high-error consonants and either degree and configuration of pure-tone hearing threshold or average consonant scores. textbf{Study II} examined how reliably a CV listening test could measure a HI listener's consonant loss using only {it zero-error} (ZE) utterances (defined as utterances for which normal hearing (NH) listeners incur zero errors, citep{singh2011}) and having a statistically suitable number of presentations in CVs, in order to characterize unique HI consonant loss. We provided graphical as well as statistical analysis to see not only the error rate (%) of a target consonant but also its pattern of specific confusions. As we found in Study I, there was no measurable correlation between pure-tone threshold and the error rate, or no identification of high-error consonants in HI ears. As noise increased, the percentage of error and confusions of target consonants increased. Although some consonants showed significantly higher errors and resulted in more confusion than others, HI ears have a very different consonant confusion pattern than NH ears, which may not be either measured or analyzed by the use of average scores. Comparison between the two (separated) phases of the experiment (Exp.~II) showed a good internal consistency for all HI ears. textbf{Study III} investigated whether or not NAL-R amplification might offer a positive benefit to speech perception of each HI listener at the consonant level, i.e., differentiates consonants that are distorted with amplification from those that achieve a positive benefit from amplification. The results were then compared to the current clinical measurement to see a relation between consonants which have positive amplification benefit and hearing loss. Regardless of NAL-R amplification, HI listeners have their own consonant dependence and the dependence was not predicted by either pure-tone threshold or aided threshold. HI listeners who have symmetrical hearing loss do not have the same positive amplification benefit to the two ears. textbf{Study IV} characterized consonant perception errors of each HI listener by identifying missing critical features of misheard consonants as a function of signal-to-noise ratio (SNR), while following the same procedure (i.e., increasing the number of ZE utterance presentations up to 20) as in Study II, yet for the NAL-R amplification condition. As the noise increased, consonant error and confusions were significantly increased, although by applying gains provided by NAL-R amplification correction. The percentage of error and confusions of the target consonants were different across the HI ears, thus could not be averaged. When the results of Study IV were compared with those of Study II, a significant amplification effect is found. Generally, the percentage of error and confusions were decreased in the NAL-R condition as a function of SNRs. However, typical average analysis, using mean score and grouping the HI ears, failed to explain the idiosyncratic characteristics of HI speech perception.\ Overall, this series of studies concluded that current average measures and analyses have a serious, even fatal limitation in finding problems of HI speech perception. Therefore, we have explored the use of the nonsense CV test for as a more precise measure. We will show that this can make significant contributions to HI speech perception. We propose that this CV test and its application might be utilized in the clinical setting, to improve the diagnosis of HI speech perception. This research will help HI listeners hear day-to-day conversations more clearly, as well as aid in audiological diagnosis and successful rehabilitation to increase speech perception for HI listeners.

Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Voice and Speech Quality Perception starts out with the fundamental question of: "How do listeners perceive voice and speech quality and how can these processes be modeled?" Any quantitative answers require measurements. This is natural for physical quantities but harder to imagine for perceptual measurands. This book approaches the problem by actually identifying major perceptual dimensions of voice and speech quality perception, defining units wherever possible and offering paradigms to position these dimensions into a structural skeleton of perceptual speech and voice quality. The emphasis is placed on voice and speech quality assessment of systems in artificial scenarios. Many scientific fields are involved. This book bridges the gap between two quite diverse fields, engineering and humanities, and establishes the new research area of Voice and Speech Quality Perception.

Available in PDF, EPUB and Kindle. Book excerpt: In our industrialized world, we are surrounded by occupational, recreational, and environmental noise. Very loud noise damages the inner-ear receptors and results in hearing loss, subsequent problems with communication in the presence of background noise, and, potentially, social isolation. There is much less public knowledge about the noise exposure that produces only temporary hearing loss but that in the long term results in hearing problems due to the damage of high-threshold auditory nerve fibers. Early exposures of this kind, such as in neonatal intensive care units, manifest themselves at a later age, sometimes as hearing loss but more often as an auditory processing disorder. There is even less awareness about changes in the auditory brain caused by repetitive daily exposure to the same type of low-level occupational or musical sound. This low-level, but continuous, environmental noise exposure is well known to affect speech understanding, produce non-auditory problems ranging from annoyance and depression to hypertension, and to cause cognitive difficulties. Additionally, internal noise, such as tinnitus, has effects on the brain similar to low-level external noise.Noise and the Brain discusses and provides a synthesis of hte underlying brain mechanisms as well as potential ways to prvent or alleviate these aberrant brain changes caused by noise exposure. - Authored by one of the preeminent leaders in the field of hearing research - Emphasizes direct and indirect changes in brain function as a result of noise exposure - Provides a comprehensive and evidence-based approach - Addresses both developmental and adult plasticity - Includes coverage of epidemiology, etiology, and genetics of hearing problems; effects of non-damaging sound on both the developing and adult brain; non-auditory effects of noise; noise and the aging brain; and more
