Abstract:

As a means of determining the accuracy and reliability of engineering calculation procedures that could be utilized as a basis for noise certification of VSTOL commercial aircraft, 36 persons made annoyance judgments to 34 noise signals presented at 5 different levels. The signals included recordings of conventional jet aircraft operations, turboprop and reciprocating engine powered commercial aircraft, helicopter flybys, and simulations of VSTOL operations. Both relative annoyance and absolute acceptability judgments were obtained.
