Compression for Clinicians: A Compass for Hearing Aid Fittings, Third Edition

Original price was: ₹8,942.00.Current price is: ₹7,154.00.

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.

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 sensorineural 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 compass in the world of compression hearing aids.

About The Author

Compression for Clinicians: A Compass for Hearing Aid Fittings, Third Edition

Theodore H. Venema, PhD, earned a BA in Philosophy at Calvin College in 1977 and an MA in Audiology at Western Washington University in 1988. After 3 years as a clinical audiologist at The Canadian Hearing Society in Toronto, he completed a PhD in Audiology at the University of Oklahoma in 1993. He was an Assistant Professor at Auburn University in Alabama for the next 2 years. From 1995 to 2001, he was a corporate audiologist at Unitron, based in Kitchener, Ontario, where he conducted field trials and gave presentations, domestically and abroad. From 2001 through 2006, he was an Assistant Professor of Audiology at Western University in Ontario. In 2006, he initiated, developed, and implemented the Hearing Instrument Specialist (HIS) program at Conestoga College in Kitchener, Ontario. He moved to Victoria, British Columbia in 2013, where he was part owner of a clinical audiology practice with NexGen Hearing. As of September 2015, Dr. Venema has been teaching on a part-time basis with the online HIS program at Ozarks Technical Community College in Springfield, Missouri. Dr. Venema continues to give presentations on various topics of hearing, hearing loss, and hearing aids at many state and provincial hearing aid associations.
