Noise control procedures instituted at an expanding heliport facility in a mixed urban/industrial area are discussed. As a measure of overall noise exposure in the vicinity of the heliport, the noise and number index is adopted; the problem of balancing the average noise level and the number of helicopter movements to achieve a specified noise exposure riding is considered. Limitations on the number of movements per year at the heliport and on the noise of individual helicopters are proposed.
