The Effects of Noise on Man covers the techniques for the evaluation of environmental noise in terms of its effects on human. The book provides the fundamental definitions of sound, its measurement, and concepts of the basic functioning, and the attributes of the auditory system. The text also presents along with their experimental basis, procedures for estimating from physical measures of noise its effects on man's auditory system and speech communications. The last part of the book is devoted to man's nonauditory system responses and includes information about the effects of noise on work performance, sleep, feelings of pain, vision, and blood circulation.
