The noise was recorded at the co-pilot's seat in a two-seat F-16, traveling at a speed of 500 knots, and an altitude of 300-600 feet. The sound level during the recording process was 103 dBA.It was found that the flight condition had only a minor effect on the noise. The reproduced noise can therefore be considered to be representative. // ------------------------------------------------------------------------------ File: noise/factory1.data.Z Noise on floor of car factory sampling rate: 19.98 KHz A/D: 16 bit pre-filter: anti-aliasing filter pre-emphasis: none filter: none duration: 235 sec length (uncompressed): approx 24 Mb Factory noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT).
