Book Description
The book is concerned with changes in the perception of sound that are associated with hearing loss and aging. Hearing loss affects about 7% of the population in developed countries, and the proportion is increasing as the average age of the population increases. The audiogram is the most widely used diagnostic tool in audiology clinics around the world. The audiogram involves measuring the threshold for detecting sounds of different frequencies. Sometimes the audiogram is the only diagnostic tool that is used. However, hearing problems are not completely characterized by the audiogram. Two individuals with similar audiograms may show very different abilities in the detection and discrimination of sounds at above-threshold levels. Also, a person may have hearing difficulties despite having an audiogram that is within the range conventionally considered as ‘normal’. One factor that may influence the discrimination of sounds, especially the ability to understand speech in background sounds, is sensitivity to temporal fine structure (TFS).This monograph reviews the role played by TFS in masking, pitch perception, speech perception, and spatial hearing, and concludes that cues derived from TFS play an important role in all of these. Evidence is reviewed suggesting that cochlear hearing loss reduces the ability to use TFS cues. Also, the ability to use TFS declines with increasing age even when the audiogram remains normal. This provides a new dimension to the changes in hearing associated with aging, a topic that is currently of great interest in view of the increasing proportion of older people in the population.The study of the role of TFS in auditory processing has been a hot topic in recent years. While there have been many research papers on this topic in specialized journals, there has been no overall review that pulls together the different research findings and presents and interprets them within a coherent framework. This monograph fills this gap.

Book Description
Binaural interference occurs when the speech input to one ear interferes with the input to the other ear during binaural stimulation. The first published study on binaural interference twenty-five years ago demonstrated that some individuals, particularly older individuals, perform more poorly with two hearing aids than with one and/or more poorly with binaural than monaural stimulation on electrophysiologic as well as behavioral measures. Binaural interference is relevant to every audiologist because it impacts the successful use of binaural hearing aids and may explain communicative difficulty in noise or other challenging listening situations in persons with normal-hearing sensitivity as well as persons with hearing loss. This exciting new book written by two highly respected audiologists first traces the history of its study by researchers, then reviews the evidence, both direct and indirect, supporting its reality. This is followed by a discussion of the possible causes of the phenomenon and in-depth analysis of illustrative cases. The authors outline a systematic approach to the clinical detection, evaluation and amelioration of individuals who exhibit binaural interference. Suggestions are furnished on improved techniques for evaluation of the binaural advantage in general and on sensitized detection of the disorder in particular. The book ends with recommendations for future directions. Given the adverse impact of binaural interference on auditory function and its occurrence in a significant subset of the population with hearing loss, as well as in some individuals with normal-hearing sensitivity, research on binaural interference only recently has begun to flourish, and adaptation of audiologic clinical practice to identify, assess, and manage individuals with binaural interference has yet to become widespread. The authors intend for the book to provide impetus for pursuing further research and to encourage audiologists to explore the possibility of binaural interference when patient complaints suggest it and when performing audiologic evaluations. The book is intended for practicing clinical audiologists, audiology students, and hearing scientists.

Book Description
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). A Reader's View of Listening (Dianne C. Bradley and Kenneth I. Forster). Prosodic Structure and Spoken Word Recognition (Francois Grosjean and James Paul Gee). Structure in Auditory Word Recognition (Lyn Frazier). The Mental Representation of the Meaning of Words (P. N. Johnson-Laird). Context Effects in Lexical Processing (Michael K. Tanenhaus and Margery M. Lucas).Uli H. Frauenfelder is a researcher with the Max-Planck-Institut für Psycholinguistik, and Lorraine Komisarjevsky Tyler is a professor in the Department of Experimental Psychology at the University of Cambridge. Spoken Word Recognition is in a series that is derived from special issues of Cognition: International Journal of Cognitive Science, edited by Jacques Mehler. A Bradford Book.

Book Description
This volume brings together noted scientists who study presbycusis from the perspective of complementary disciplines, for a review of the current state of knowledge on the aging auditory system. Age-related hearing loss (ARHL) is one of the top three most common chronic health conditions affecting individuals aged 65 years and older. The high prevalence of age-related hearing loss compels audiologists, otolaryngologists, and auditory neuroscientists alike to understand the neural, genetic and molecular mechanisms underlying this disorder. A comprehensive understanding of these factors is needed so that effective prevention, intervention, and rehabilitative strategies can be developed to ameliorate the myriad of behavioral manifestations.

Book Description
Speech and Language: Advances in Basic Research and Practice, Volume 8 provides articles that discuss a broad range of topics on speech and language processes and pathologies. This volume contains nine contributions covering a wide array of topics on speech and language. Certain chapters review the literature on speech-sound development in normally developing and deviant children; the scope of the problem of stuttering and the three prominent theoretical positions on anxiety in stuttering; and critical issues in the linguistic study of aphasia. Discussions on such topics as speech production characteristics of the hearing impaired; ontogenetic changes in children's speech-sound perception; and the impact of linguistic theory on the description and treatment of articulation disorders are also presented. Linguists, speech pathologists, and researchers on language development will find the book very insightful and informative.
