Compression for Clinicians

Explains hearing aid compression, fitting methods, and real ear measurement for those studying to become hearing health care professionals, including audiologists and hearing instrument practitioners.

"Compression for Clinicians: Considerations 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. Directional microphones and digital features of noise reduction, feedback reduction, and expansion are also covered. The text aims to make difficult concepts easier to understand and to explain in plain language many topics pertaining to compression. The third edition recognizes two distinct clinical populations of sensori-neural hearing loss; mild-to-moderate on the 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.New to 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 sensori-neural hearing loss*Contains updated coverage of digital hearing aids, directional microphones, and digital noise reduction*Retains 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 relevant compass in the world of compression hearing aids.
