The concept of compression, in one sentence, is the way in which soft vs. medium vs. loud sounds are handled by a hearing aid. Compression for Clinicians, 2nd Edition is a basic text designed to provide the audiology student, clinician, or anyone fitting hearing aids (hearing aid dispensers) with an easy-to-read review and explanation of the concepts underlying signal compression in hearing aids so that they can understand how to apply these concepts to selecting and fitting hearing aids. The book covers anatomic and physiologic description of the cochlea, an overview of hearing aid fitting methods, understanding loudness growth functions, the many ways compression is incorporated in hearing aids, the major classes of hearing aids and their capabilities and limitations, and how compression is a factor in various hearing aid selection methods.
