Discussed are the sources of noise in ships and explains the bases for controlling noise abration in ships. A short treatment of the fields of physical physiological and structural acoustics, as well as acoustical measurements, is presented. Modern methods of sound and vibration insulation, and sound and vibration absorption, and methods for measuring these values are described. The causes of the origin of vibrations in machinery and mechanisms are analyzed, and several means and methods for controlling these vibrations are indicated. The material discussed is illustrated by examples and calculations.
