The influence of noise on production and fatigue, as related to pitch, sensation level, and steadiness of the noise

Abstract

"Four healthy young men" worked on a dotting machine under varying noise conditions regulated through an audiometer. Varying complex noise reduces production. A complex but steady noise decreases production more than a relatively pure tone. Observations of the subject under more intense noises showed muscular stiffness in the neck and legs and a "great increase" in the volume of urine excreted.
