One reason for such difficulty may be a decreased ability to process the rapid changes in intensity, frequency, or temporal information that serve to differentiate speech sounds. Two important cues for the identification of stop consonants are the duration of the interruption of airflow (i.e., closure duration) and rapid spectral changes following the release of closure. Many researchers have shown that age and hearing loss affect a listener's cue weighting strategies and trading relationship between spectral and temporal cues. The study of trading relationships between speech cues enables researchers to investigate how much various listeners rely on different speech cues. Different cue weighting strategies and trading relationships have been demonstrated for individuals with hearing loss, compared to listeners with normal hearing. These differences have been attributed to the decreased ability of the individuals with hearing loss to process spectral information. While it is established that processing of temporal information deteriorates with age, it is not known whether the speech processing difficulties of older listeners are due solely to the effects of hearing loss or to separate age-related effects as well. The present study addresses this question by comparing the performance on a series of psychoacoustic and speech identification tasks of three groups of listeners (young with normal-hearing, older with normal-hearing, and older with impaired hearing) using synthetic word pairs ("slit" and "split"), in which spectral and temporal cues are altered systematically. Results of the present study suggest different cue weighting strategies and trading relationships for all three groups of listeners, with older listeners with hearing loss showing the least effect of spectral cue changes and young listeners with normal hearing showing the greatest effect of spectral cue changes. Results are consistent with previous studies showing that older listeners with and without hearing loss seem to weight spectral information less heavily than young listeners with normal hearing. Each listener group showed a different pattern of cue weighting strategies when spectral and temporal cues varied.

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: Purpose: This study was designed to investigate (1) the effects of age and hearing loss on auditory neural coding, (2) interrelationships between auditory evoked potentials (AEP) taking place at early and later stage of auditory processing, and (3) electrophysiological correlates of age-related declines in speech-in-noise perception. Methods: 30 young normal-hearing adults (YNH, M=21 years), 26 older adults with near-normal hearing (ONH, M=63.9 years) and 26 older adults with hearing loss (OHL, M=72.8 years) participated in the study. AMLR Pa and N1, P2 and N2 of ALLRs were recorded using two-channel electrode system. 500 Hz tone burst and syllable /ba/ were presented in quiet and in babble at the level of 90 Leq (dBA), accompanied by babble at the level of 65 Leq (dBA). Revised Speech Perception in Noise (R-SPIN) test was conducted to measure speech-in-noise perception. Results: ONH listeners demonstrated significantly enhanced Pa and N1 amplitudes and significantly prolonged Pa, P2 and N2 latencies compared with YNH listeners, indicating the effects of aging. OHI group demonstrated significantly prolonged N2 latencies compared with ONH group, indicating the effects of hearing loss. OHI listeners demonstrated significantly enhanced amplitudes and significantly prolonged latencies across all AEP components compared with YNH listeners, indicating that the combined effects may have stronger impacts on age-related changes in AEP morphology. Significant correlations between the amplitudes of Pa and each component of ALLRs were found in ONH and OHI groups, indicating that enhanced Pa amplitudes correspond with enhanced amplitudes of cortical responses in older listeners. Significant correlations between latencies of Pa and each component of ALLRs were found in all groups, indicating that prolonged Pa latencies correspond with prolonged latencies of cortical responses in all listeners. In both ONH and OHI groups, lower R-SPIN-LP scores are significantly correlated with enhanced Pa, P2, and N2 amplitudes and prolonged N2 latencies, particularly for syllable /ba/. Discussion and Conclusions: Interplay between effects of aging and hearing loss may have stronger impacts on morphological changes in the AEP waveforms. Amplitude-based interrelationships reflect age-related changes in a transfer of neural information between subcortical and cortical auditory network. Latency-based interrelationships indicate the association between neural timings at subcortical and cortical levels. Age-related enhancements of Pa, P2 and N2 amplitudes and age-related prolongations of N2 latencies may serve as electrophysiological correlates of age-related declines in SIN perception.

Book excerpt: The field of Binaural Hearing involves studies of auditory perception, physiology, and modeling, including normal and abnormal aspects of the system. Binaural processes involved in both sound localization and speech unmasking have gained a broader interest and have received growing attention in the published literature. The field has undergone some significant changes. There is now a much richer understanding of the many aspects that comprising binaural processing, its role in development, and in success and limitations of hearing-aid and cochlear-implant users. The goal of this volume is to provide an up-to-date reference on the developments and novel ideas in the field of binaural hearing. The primary readership for the volume is expected to be academic specialists in the diverse fields that connect with psychoacoustics, neuroscience, engineering, psychology, audiology, and cochlear implants. This volume will serve as an important resource by way of introduction to the field, in particular for graduate students, postdoctoral scholars, the faculty who train them and clinicians.

Available in PDF, EPUB and Kindle. Book excerpt: Spoken Word Recognition covers the entire range of processes involved in recognizing spoken words - both in and out of context. It brings together a number of essays dealing with important theoretical questions raised by the study of spoken word recognition - among them, how do we understand fluent speech as efficiently and effortlessly as we do? What are the mental processes and representations involved when we recognize spoken words? How do these differ from those involved in reading written words? What information is stored in our mental lexicon and how is it structured? What do linguistic and computational theories tell us about these psychological processes and representations?The multidisciplinary presentation of work by phoneticians, linguists, psychologists, and computer scientists reflects the growing interest in spoken word recognition from a number of different perspectives. It is a natural consequence of the mediating role that lexical representations and processes play in language understanding, linking sound with meaning.Following the editors' introduction, the contributions and their authors are: Acoustic-Phonetic Representation in Word Recognition (David B. Pisoni and Paul A. Luce). Phonological Parsing and Lexical Retrieval (Kenneth W. Church). Parallel Processing in Spoken Word Recognition (William D. Marslen-Wilson).

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigates the impact of various types of cochlear hearing loss and mask- ing noise on the perception of basic speech sounds based on the information of identified speech cues. A psychoacoustic method, named three-dimensional deep search (3DDS), is developed to identify the perceptual cues of consonant sounds in natural speech. Unlike the conventional method of synthetic speech, which requires a prior hypothesis about the acoustic cues to generate the speech stimuli, the 3DDS measures the contribution of each subcomponent to speech perception as a function of time, frequency and intensity, without making any tacit assumptions about the speech cues to be identified. Using the 3DDS, we discovered that natural speech often contains conflicting cues that are characteristic of confusable sounds. For instance, a normal /ka/, dominated by a mid-frequency burst at 10́32 kHz, may also have an inaudible /ta/ burst above 3 kHz that promotes the /ka/6́2/ta/ confusion under noisy environments. Removal of the /ka/ burst may turn the sound into a solid /ta/. More than a dozen hearing-impaired ears were tested on consonant identification in noise. While the deterioration in performance for flat mild-to-moderate hearing loss can be well predicted by the loss of audibility, subjects with other types of hearing loss often show patterns of difficult sounds that can hardly be explained by the shift of hearing threshold. A subject with almost identical binaural hearing loss is nearly deaf to /ka/ in one ear due to a mid-frequency cochlear dead region. Among the 18 /ka/s produced by different talkers, the subject can only hear one /ka/ at an accuracy of 80% and three other /ka/s at 200́340%. Most /ka/s are highly confused with /ta/ because the subject is listening to the conflicting /ta/ burst in the high-frequency. The /ka/6́2/ta/ confusion is significantly reduced when the conflicting cue is removed. NAR-L improves the average score by 10%, but it may degrade a few consonants under certain circumstances.

Book excerpt: This book is one outcome of the NATO Advanced Studies Institute (ASI) Workshop, "Speechreading by Man and Machine," held at the Chateau de Bonas, Castera-Verduzan (near Auch, France) from August 28 to Septem ber 8, 1995 - the first interdisciplinary meeting devoted the subject of speechreading ("lipreading"). The forty-five attendees from twelve countries covered the gamut of speechreading research, from brain scans of humans processing bi-modal stimuli, to psychophysical experiments and illusions, to statistics of comprehension by the normal and deaf communities, to models of human perception, to computer vision and learning algorithms and hardware for automated speechreading machines. The first week focussed on speechreading by humans, the second week by machines, a general organization that is preserved in this volume. After the in evitable difficulties in clarifying language and terminology across disciplines as diverse as human neurophysiology, audiology, psychology, electrical en gineering, mathematics, and computer science, the participants engaged in lively discussion and debate. We think it is fair to say that there was an atmosphere of excitement and optimism for a field that is both fascinating and potentially lucrative. Of the many general results that can be taken from the workshop, two of the key ones are these: • The ways in which humans employ visual image for speech recogni tion are manifold and complex, and depend upon the talker-perceiver pair, severity and age of onset of any hearing loss, whether the topic of conversation is known or unknown, the level of noise, and so forth.

This book was released on 2015 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been proposed in the literature that if too many processing resources need to be devoted to perception then higher-order cognitive functions, such as working memory (WM), may suffer. This effect may be particularly evident in individuals who have restricted processing resources, such as older adults (OA) suffering from hearing loss or cognitive impairment. One possibility to facilitate perception during speech processing is through the auditory-visual (AV) modality. The current research examined whether AV speech perception helps to facilitate perceptual and WM processing in OAs with restricted processing resources. In both studies, participants completed a WM n-back task under different speech modalities: AV, auditory-only, or visual-only (Study 1). Both behavioural and event-related potentials (ERPs) measures were collected during the task. Study 1 examined the effect of AV speech on WM in OAs with hearing impairment compared to normal-hearing OAs. The results showed that AV speech in comparison to auditory-only speech led to facilitated perceptual processing in OAs with hearing impairment, as indicated by ERP responses. The AV modality also led to facilitated WM functioning in both groups, as suggested by ERP responses and behavioural reaction time. A few measures indicated that visual speech cues may have helped OAs with hearing impairment to counteract the demanding auditory processing. Study 2 examined the effect of AV speech on WM in OAs suffering from mild cognitive impairment (MCI) or Alzheimer disease (AD) compared to cognitively healthy OAs. The ERP responses showed that the AV modality compared to the auditory-only modality led to facilitated perceptual and WM processing in both groups. In addition, the behavioural results showed improved accuracy during the WM task for the patient group, and faster reaction time for both the patient group and the cognitively healthy control group. Overall, the results showed that OAs with hearing or cognitive impairment benefit from AV speech in terms of improved WM performance. In fact, there were a few indications that the AV benefit may be even more robust in these groups than in cognitively healthy OAs. The theoretical and practical implications of these findings and directions for future research are discussed.
