Abstract
Noise-dosimeter readings were taken under the earphones of a number of Transport Canada radio operators working the high- and medium-frequency bands (0.3 to 30 MHz), on each eight-hour shift during seven- and ten-day periods in June and July 1981 at the Gander Flight Service Station and the Vancouver Coast Guard Radio Station. In addition, copies of the most recent audiograms on file for 363 of the operators were collected from regional Health and Welfare centers across Canada. In order to supplement these data, a questionnaire was prepared and distributed through Transport Canada to as many radio operators as possbile, requesting information on non-occupational and pre-employment noise exposures and any family history of hearing loss.
