Noise

This study first describes the nature of sound to give the reader a basis for understanding the principles and techniques for its measurement and to analyze sound and noise. Subjective and psychological aspects are then considered, including such questions as: what are the annoying features of noise? How is noise rated? How much noise is needed to cause deafness? The final and most important section deals with the control of noise. Traditional methods and more recent developments, such as active control, are included. The subject matter keeps in mind the regulations and legal requirements that have made noise an important issue.
