Extract

Following upon an experiment on the subjective effects of jet engine noise we have recently undertaken a similar experiment, this time on the subjective aspects of helicopter noise. The purpose of the earlier experiment was to determine the reliability of various methods of rating based on spectrum analysis, so far as comparisons between jet- and piston-engined aircraft are concerned. The main objective of the present experiment was to find if these methods are applicable to the pulsating types of noise characteristic of helicopters.
