Sound and Noise Level Measurements

Abstract

Due to the demands of the public, recent legislation has been enacted to curb noise emanations from a multitude of sources. This has caused concern in industry in two ways. "First, the various noise levels under which a product is manufactured must be maintained within the law to prevent hearing damage risk to production workers. Second, the noise level generated by the operation of a particular product must be within designated standards. In the latter case, the annoyance of the sound level output is generally more important than the hearing damage risk for consumer products because of their reduced emissions.
