Book Description
Poster session presented at the meeting of the American Auditory Society, Scottsdale, AZ). In both experiments, the outcome measures were administered following the hearing aid fitting to establish baseline performance and after two months of use. Results revealed no significant difference between the frequency-compression and conventional hearing aid on tests of localization and consonant recognition. Spondee-in-noise and vowel perception scores were significantly higher with the conventional hearing aid compared to the frequency-compression hearing aid after two months of use. These results suggest that, for the subjects in this study, frequency compression is not a better bimodal option than conventional amplification. In addition, speech perception may be negatively influenced by frequency compression because formant frequencies are too severely compressed and can no longer be distinguished.

Book Description
The Springer Handbook of Auditory Research presents a series of comp- hensive and synthetic reviews of the fundamental topics in modern au- tory research.The volumes are aimed at all individuals with interests in hearing research including advanced graduate students, post-doctoral researchers, and clinical investigators.The volumes are intended to int- duce new investigators to important aspects of hearing science and to help established investigators to better understand the fundamental theories and data in ?elds of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the lit- ature.As such the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals.The volumes focus on topics that have developed a solid data and conceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature.

Book Description
Compression for Clinicians: A Compass for Hearing Aid Fittings, Third Edition explains many developments that have taken place in the world of hearing aid compression, fitting methods, and real ear measurement. The text aims to make difficult concepts easier to understand and to explain in plain language many topics pertaining to compression. Directional microphones and digital features of noise reduction, feedback reduction, and expansion are also covered. The third edition recognizes two distinct clinical populations of sensorineural hearing loss: mild to moderate, on one hand, and more severe, on the other. These two clinical populations are well served by a corresponding pair of compression types: wide dynamic range compression and output limiting compression. Another double distinction held throughout the text is the two-part task for all hearing aids: providing gain and also increasing the signal-to-noise ratio. Gain is addressed by compression, while listening in noise is addressed by directional microphones and digital noise reduction. The Third Edition: Includes new chapters on common clinical encounters (Chapter 1), real ear measurement (Chapter 5), and adaptive dynamic range optimization (Chapter 10)Distinguishes between "sensory" and "neural" hearing loss and devotes a separate chapter to each of these types of sensorineural hearing lossContains updated coverage of digital hearing aids, directional microphones, and digital noise reductionRetains a strong focus on the historical development of compression from yesterday's analog hearing aids to digital hearing aids of today Compression for Clinicians is intended for those studying to become hearing health care professionals, including audiologists and hearing instrument practitioners. It is also intended for practicing clinicians who simply want to refresh their knowledge base concerning hearing loss and hearing aids. Clinically relevant and very thorough, it provides a compass in the world of compression hearing aids.

Book Description
A unique and up-to-date review for ENT surgeons, audiologist and researchers Three decades after the introduction of the first bone-anchored hearing aids, the available systems have improved significantly and the field is expanding faster than ever. New technologies such as digital signal processing have opened new avenues unique to bone conduction hearing aids. Better insights into the physiology of bone-conducted hearing have not only changed the field but also provided ideas for new areas of application. In this volume of Advances in Oto-Rhino-Laryngology, renowned researchers and experienced clinicians from all over the world present the latest findings and practices. Reviews on the theoretical background of bone conduction hearing, presentation of currently available hearing aid systems, chapters on monaural and binaural hearing with implantable bone conduction hearing aids, a comparison with conventional hearing aids and a glimpse into the future of implantable bone conduction hearing aids render this volume an invaluable reference book to ENT surgeons, audiologists, hearing aid acousticians and researchers alike.

Book Description
Congenital or acquired hearing impairments put children at risk of delayed language development. Today the cochlear implant (Cl) is a viable amplification option for some children with profound hearing losses. Audiologists often recommend that children with hearing impairments be fitted with binaural hearing aids in the hope that maximum stimulation will occur and that auditory deprivation will be lessened. An area lacking investigation is whether binaural stimulation will be beneficial to the cochlear implant recipient. Controversy also exists regarding the use of a hearing aid in the non-implanted ear. The focus of this study was to compare binaural auditory stimulation benefits for children who have a Cl and a hearing aid in the non-implanted ear with those children who use the implant alone using a group statistical design. Fourteen children with a Cl and also enrolled in an auditory-oral training program took part in this study. Eight of these children also wear a hearing aid in the non-implanted ear. The investigation incorporated the Early Speech Perception Test (ESP) to assess the auditory perception abilities of children in the two groups. The results of the regression analysis revealed that duration of Cl use did not significantly impact subtest scores on the ESP test. Regression analysis also revealed a significant difference in scores between the two groups at the .05 level on the standard pattern/perception and word identification tests while no significant differences were noted between the groups on the spondee identification and monosyllable identification tests. The difference noted between the groups on the standard pattern/perception and word identification tests could have been influenced by the low level of processing skills required to complete the tasks. The results of the current investigation, at least as presented in this study, revealed that the auditory perception performance of the Cl and Cl + hearing aid groups were similar and no significant difference was noted overall on the ESP test, though there were some significant differences in certain subtests. If nothing else, this study supports the use of both devices with no adverse effects on performance.

Book Description
Cochlear implants are currently the standard treatment for profound sensorineural hearing loss. In the last decade, advances in auditory science and technology have not only greatly expanded the utility of electric stimulation to other parts of the auditory nervous system in addition to the cochlea, but have also demonstrated drastic changes in the brain in responses to electric stimulation, including changes in language development and music perception. Volume 20 of SHAR focused on basic science and technology underlying the cochlear implant. However, due to the newness of the ideas and technology, the volume did not cover any emerging applications such as bilateral cochlear implants, combined acoustic-electric stimulation, and other types of auditory prostheses, nor did it review brain plasticity in responses to electric stimulation and its perceptual and language consequences. This proposed volume takes off from Volume 20, and expands the examination of implants into new and highly exciting areas. This edited book starts with an overview and introduction by Dr. Fan-Gang Zeng. Chapters 2-9 cover technological development and the advances in treating the full spectrum of ear disorders in the last ten years. Chapters 10-15 discuss brain responses to electric stimulation and their perceptual impact. This volume is particularly exciting because there have been quantum leap from the traditional technology discussed in Volume 20. Thus, this volume is timely and will be of real importance to the SHAR audience.
