Amazon.com description: Product Description: Understanding the array and complexity of instrumentation available to audiologists and hearing scientists is important to students, beginning clinicians indeed even seasoned professionals. This new textbook is a comprehensive and accessible look at instrumentation used in these fields. The expert authors introduce the laws of physics as they relate to audiology and hearing science and explain concepts in electronics directly related to instrumentation used in audiology and hearing science (filtering, immittance, digital signal processing including FFT, power reflectance, microphones, receivers, amplifiers, and so forth). They also provide an invaluable introduction to digital technology and further cover details on the calibration of equipment (ANSI standards, audiometer, otoacoustic emissions, and other evoked potentials). The book, reviewed by internationally renowned experts and with a foreward by Dr. James Jerger, is abundantly illustrated with analog and digital models and also includes instrumentation demonstrations on an accompanying DVD.
