Abstract : The report presents technical information and procedures for estimating the noise levels produced by current civil and military helicopters (piston- and turbine-powered) during varied flight and ground operations. Information and procedures are also presented for comparing helicopter noise with other vehicle noise, and with ambient noise found in typical urban and suburban areas. These procedures permit an assessment of the extent to which helicopter noise is compatible with typical land uses (residential, commercial, industrial, etc.) in areas near heliports. Noise data and procedures are presented in simplified fashion. The information may be readily used by those without specialized acoustical training but who are concerned with the location and development of a heliport, or with land planning or land zoning in the vicinity of heliports.
