Industrial Noise Control and Acoustics

NOISE CONTROL
Concern about problems of noise in the workplace and in the living space
has escalated since the amendment of theWalsh–Healy Act of 1969. This act
created the ﬁrst set of nationwide occupational noise regulations
(Occupational Safety and Health Administration, 1983). There is a real
danger of permanent hearing loss when a person is exposed to noise
above a certain level. Most industries are strongly motivated to ﬁnd an
effective, economical solution to this problem.
The noise level near airports has become serious enough for some
people to move out of residential areas near airports. These areas were
considered pleasant living areas before the airport was constructed, but
environmental noise has changed this perception. The airport noise in the
areas surrounding the airport is generally not dangerous to a person’s
health, but the noise may be unpleasant and annoying.
In the design of many appliances, such as dishwashers, the designer
must be concerned about the noise generated by the appliance in operation;
otherwise, prospective customers may decide to purchase other quieter mod-
els. It is important that noise control be addressed in the design stage for
many mechanical devices.
