Soun is nought but air y-broke —Geoffrey Chaucer end of the 14th century Traditionally, acoustics has formed one of the fundamental branches of physics. In the twentieth century, the ?eld has broadened considerably and become - creasingly interdisciplinary. At the present time, specialists in modern acoustics can be encountered not only in physics departments, but also in electrical and mechanical engineering departments, as well as in mathematics, oceanography, and even psychology departments. They work in areas spanning from musical instruments to architecture to problems related to speech perception. Today, six hundred years after Chaucer made his brilliant remark, we recognize that sound and acoustics is a discipline extremely broad in scope, literally covering waves and vibrations in all media at all frequencies and at all intensities. This series of scienti?c literature, entitled Modern Acoustics and Signal P- cessing (MASP), covers all areas of today’s acoustics as an interdisciplinary?eld. It offers scienti?c monographs, graduate-level textbooks, and reference materials in such areas as architectural acoustics, structural sound and vibration, musical acoustics, noise, bioacoustics, physiological and psychological acoustics,speech, ocean acoustics, underwater sound, and acoustical signal processing.

The cochlear implant is a device that bypasses a nonfunctional inner ear and stimulates the auditory nerve directly with patterns of electrical currents derived from incoming sounds. The culmination of investigations in many disciplines, it is the first major advance in helping profoundly deaf children communicate since the Sign Language for the Deaf was developed at the Institution des Jeunes Sourds in Paris some 200 years ago. Written by the "father" of the multi-electrode implant, this comprehensive text and reference gives an account of the fundamental principles underlying cochlear implants and their clinical application.It thus discusses research in all relevant disciplines, including: - Surgical anatomy, concentrating on essentials relevant to engineering - Pathology, focusing on the inner ear's response to the implant and to electrical stimulation - Biophysics and electrochemistry, addressing the interface between electrode and tissue - Neurobiology, with particular emphasis on the issue of safety - Physiology, summarizing current theories of frequency and amplitude coding - Psychophysics, focusing on pitch and loudness perception - Speech science, including phonetics, perception, and language - Electronic principles of signal processing needed for speech perception - Clinical factors of importance to the engineering - Surgical procedures to help scientists and engineers understand the realities for implant development - Communication skills achieved for different speech processing strategies.
