Abstract
The paper discusses current problems in hearing conservation in the Canadian Forces and describes developments which may help to alleviate these problems in the future. Active noise reduction, the electronic canceling of noise, is capable of increasing the low-frequency attenuation of ear muffs and flight helmets by about 15 dB. Speech-signal conditioning (e.g., voice operated switching, active noise canceling) will reduce noise exposures reaching the ear through flight-helmet or headset earphones. A computer-based audiometer with data base capabilities has been developed to facilitate audiometric testing and data analysis.
