Physiological Effects of Intense Sound

Abstract

Conclusions: Noise fields sufficiently intense seriously impair human hearing. These noise fields are produced by turbo-jet power plants currently in use; The frequency spectrum of the turbo-jet noise field is such that the hearing loss produced in man interferes markedly with the reception and understanding of speech; Sound energy will kill rats and guinea pigs; Effects reported have been produced by intense sound fields in the audible range; Because the effects described have been the result of exposure to intense sound in the audible range it is suggested that the important parameter may be intensity rather than frequency.
