The Hearing Sciences, Third Edition

This textbook addresses all topics critical to understanding the hearing sciences: acoustics, basic instrumentation, anatomy and physiology of the auditory and vestibular systems, and psychoacoustics. The text is intended for undergraduate courses in hearing science and to augment the graduate AuD curriculum. Basic and intermediate chapters are targeted to undergraduate students. Intermediate and advanced chapters are appropriate for AuD instruction.

Alternative Formula for Impedance.
