A discussion on the origin and treatment of noise in industrial environments - Noise and engineering design

Abstract

The paper presents a short account of various investigations carried out on the basic mechanism of noise produced by machines involving solid structures. The emitted noise of the machine is generally due to bending vibration of either the outer or inner surfaces or both. In vehicles, for example, consideration of both the internal and external surfaces is of importance: vibrations of the internal surfaces produce noise inside the cab or car saloon and this affects the driver and passengers, while the external surfaces produce the noise which affects the community
