Helicopter Noise Data Letter Report DTS-75-FA053-LR8 (Rev. 1)

One-third octave spectral noise data are provided for 15 helicopters from the Transportation Systems Center (TSC) Helicopter Noise Data Library. The original data were measured by TSC in 1978 through 1983 and published in prior reports. The data have been adjusted to reference conditions at a reference altitude of 1000 feet, utilizing the Society of Automotive Engineers (SAE) standard atmosphere. The data are presented for the record at time of PNLTmax for a representative event, one each for takeoff, approach and level flyover.
