Abstract
The problems of relating noise exposure to changes in auditory thresholds are discussed. The threshold shift may be brought about by factors other than noise, and noise exposure is difficult to define. Permanent threshold shifts from any noise source are extremely difficult to study, and most work has been done on temporary shifts, with the presumption that the two are related. The recovery from temporary threshold shifts resulting from continuous and intermittent noise of different levels are discussed. The variables frequency, decibels and time all affect this process. The present standard for noise exposure of eight hours at 90 decibels A with a five decibel (per halving exposure time) trading relation should be retained.
