Abstract
Results of noise surveys performed at two major airports are presented, including (a) measurement of operational noise in the working areas and evaluation of potential danger to hearing, (b) audiometric data from airport employees, and (c) determination of noise in nearby residential areas. Potentially harmful noise levels were found at ground run-up, taxi, and take-off operations and in the area of engine test-cell facilities. Both jet and propeller aircraft produced annoyance noise levels in the residential areas, with jet noise being the greater problem.
