Book Description
Otoacoustic Emissions (OAEs) are sounds generated by an active process in the auditory system's cochlea. It has been widely accepted that the generation of OAEs is a precursor for healthy hearing. The measurement of evoked OAEs can be used to determine the general health of the cochlea and basilar membrane's response and sound transmission forward and backwards through the inner ear. OAEs are commonly used for newborn infant hearing screening where many middle ear pathologies are first detected. In most cases, secondary screening tests such as tympanometry are not conducted unless the patient has failed the OAE screening first. Increases in ear canal pressure have an almost identical effect on OAE recordings when compared to naturally occurring negative middle ear pressures (NMEPs) (Sun & Shaver, 2009). Thus arises the need for pressure compensated OAE screening. This study aims at reviewing the design of a self-compensating pressure system capable of generating steady meatal pressures during OAE subject screening. Facets of system design including patient safety, software interaction, and initial test results will be presented. We will also present the results of an IRB sanctioned volunteer study which collected the TEOAE and meatal responses of 20 individual ears during multiple pressure criteria. Testing and analysis of signals in both the time and frequency domains will be reviewed.

Book Description
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.

Book Description
A practical guide to auditory electrophysiology, from the laboratory to the clinic Auditory Electrophysiology: A Clinical Guide, Second Edition by auditory electrophysiology clinicians, researchers, and educators Samuel R. Atcherson and Tina M. Stoody fills a gap in the literature. The second edition features up-to-date text and references on all aspects of auditory evoked potentials (AEPs). New perspectives include automated newborn hearing screening, frequency-specific auditory brainstem response assessments, differential diagnosis of auditory neuropathy spectrum disorder, evaluation of balance and fall risk assessment, central auditory function testing, surgical applications, and animal audiology. The first section includes four chapters on the foundational science and instrumentation of AEPs. Section two starts with a chapter on electrocochleography, followed by six chapters discussing various responses and potentials. Section three features eight chapters focused on clinical applications with relevant case studies. The final section provides practical guidance on various aspects, from patient-related management to stimulation calibration and generation. Key Features New contributions from 20 nationally and internationally recognized experts Major updates to the vestibular AEP chapter Reader-friendly section organization and tables facilitate acquisition and retention of knowledge Boxed pearls, pitfalls, and special considerations provide insightful, easy-to-read references An added animal audiology chapter offers the potential for clinicians to expand their scope of practice This textbook is essential reading for graduate students in audiology and ENT residents, as well as seasoned clinicians who wish to refresh their skills or expand their practice.

Book Description
The cochlea does not just pick up sound, it also produces sounds of low intensity called Otoacoustic Emissions (OAEs). Sounds produced by healthy ears – either spontaneously or in response to stimuli - allow researchers and clinicians to study hearing and cochlear function noninvasively in both animals and humans. This book presents the first serious review of the biological basis of these otoacoustic emissions.

Book Description
Tinnitus is the perception of a sound when no external sound is present. The severity of tinnitus varies but it can be debilitating for many patients. With more than 100 million people with chronic tinnitus worldwide, tinnitus is a disorder of high prevalence. The increased knowledge in the neuroscience of tinnitus has led to the emergence of promising treatment approaches, but no uniformly effective treatment for tinnitus has been identified. The large patient heterogeneity is considered to be the major obstacle for the development of effective treatment strategies against tinnitus. This eBook provides an inter- and multi-disciplinary collection of tinnitus research with the aim to better understand tinnitus heterogeneity and improve therapeutic outcomes.
