Cockpit Noise Exposures Associated with The Operation of Fixed-and Rotary-Wing Aircraft

摘要

Noise levels measured within the cockpits of 126 fixed- and rotary-wing aircraft were tabulated and arranged into stereotyped sets of exposure envelopes. The noise data from which these envelopes were derived represent 'typical' unprotected exposures encountered within 12 different categories of fixed- and rotary-wing aircraft during conditions of 'normal cruise.' Extreme or unique noise exposures were deleted from the study. (Author)
