Acoustics for Audiologists
This book is devoted to the acoustical principles that underlie the de sign and fitting of hearing aids. It includes coverage of basic acoust ics, including a full, but mostly nonmathematical discussion of the de cibel unit, air-coulmn and Helmoltz acoustical resonance, horns, the e ffect of the acoustical transmission path of the ear on hearing-aid re sponse, psychoacoustics, amplification systems of hearing aids (includ ing signal processing and class D and digital circuitry), and noise-re duction system. These subjects are discussed in terms of their specifi c applications to the design and fitting of hearing aids. The book pre sents the information in simple understandable terms.
