Impulse noise: a complex industrial hazard.

NIOSH 1978 Jan; :1-23
The variety of factors which influence the degree of noise induced permanent threshold shift (NIPTS), including impulse noise in industry, are discussed. A number of experimental results centering around four topics were discussed: 1) impulse noise: compounding problems of microstructure; 2) impulse noise: potentiating effects; 3) noise plus vibration: potentiating effects; and 4) noise and drug interaction. It is noted that the detailed structure of the impulse noise is of importance in determining its effects. The addition of impulses to background noise adds very little to the total acoustic energy entering the ear. A group exposed to the combined effects of noise and vibration sustained greater losses of sensory cells within the cochlea than a group exposed to noise alone. It is noted that persons working or living in high level noise environments may run an increased risk of auditory damage when they are on a schedule of aminoglycoside antibiotic therapy. Persons on other drugs may also face increased risk.
