Book Description
electroacoustics This branch of acoustic engineering deals with the design of headphones, microphones, loudspeakers, sound systems, sound reproduction, and recording.[15] There has been a rapid increase in the use of portable electronic devices which can reproduce sound and rely on electroacoustic engineering, e.g. mobile phones, portable media players, and tablet computers. This term is also used for a set of electrokinetic effects that occur in heterogeneous liquids under influence of ultrasound. There is International Standard that describes such electroacoustic effects in details

Book Description
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.[1] Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimeters (0.67 in). Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician, while someone working in the field of acoustical engineering may be called an acoustical engineer.[2] An audio engineer, on the other hand, is concerned with the recording, manipulation, mixing, and reproduction of sound. Applications of acoustics are found in almost all aspects of modern society, subdisciplines include aeroacoustics, audio signal processing, architectural acoustics, bioacoustics, electro-acoustics, environmental noise, musical acoustics, noise control, psychoacoustics, speech, ultrasound, underwater acoustics, and vibration.

Book Description
Handbook of Perception, Volume IV: Hearing reviews the literature on the physical, physiological, and psychological aspects of hearing. The book covers a wide array of topics relevant to hearing, including the measurement and biophysics of the cochlea, binaural and spatial hearing, and the effects of hearing impairment on the auditory system. The psychological, sociological, and physiological effects of noise are also addressed. This volume is organized into six sections encompassing 16 chapters and begins with a historical overview of the history of research on hearing, from the antiquity of acoustics to the physical and mathematical developments that gave rise to auditory facts and theories. Auditory perception, physiology, and theory are followed up to about 1940, whereas the work on analysis synthesis and perception of speech is traced up to about 1960. The chapters that follow focus on measurement, the biophysics of the cochlea, and neural coding. The underlying mechanisms of the processing of acoustic information are given consideration. The book methodically introduces the reader to the mechanisms of frequency, intensity, time, and periodicity, along with stress, trauma, and pathology. A chapter on the transient physiological effects of noise and their relation to neuroendocrine stress theory concludes the treatise. This book is intended for psychologists, biologists, and natural scientists, as well as for those who are interested in the physical, physiological, and psychological aspects of hearing.
