【 摘 要 】

Observations in simulator studies suggested that the older segments of the general aviation pilot population were having difficulty hearing specific auditory warnings in the cockpit. These observations, in combination with data from Tobias (1968a; 1968b; 1972), prompted a reexamination of the hearing capabilities of pilots and non-pilots. In Phase 1, threshold data were collected for 150 non-pilots and 150 pilots using stratified age sampling. The usual higher-frequency decrements attributable to aging and general environmental exposure were found in both samples.
