TTS FROM NEIGHBORHOOD AIRCRAFT NOISE
In an attempt to determine the effect on the auditory threshold of the worst "neighborhood" exposure to aircraft noise that can reasonably be expected, tape-recorded overpasses, both landings and takeoffs, were reproduced at 111 dBA peak level in a reverberant room. Six-hour exposures to landings or takeoffs at the rate of 1 per 1.5 or 3 min were given to one of two groups of five normal listeners. The mean TTS sub 2 (temporary threshold shift 2 min after exposure) did not reach 5 dB at any frequency in any condition. The possibility of hearing damage from such exposures is therefore judged to be remote, despite the fact that the 8-h "equivalent levels" of these exposures are as high as 90 dBA. The importance of interruptions in reducing risk is emphasized.
