Authors Abstract
Content
The rapidly increasing number of aircraft passengers requires improved techniques for aircraft manufacturers to provide high internal comfort for passengers and the crew. In this paper, the internal acoustic comfort was evaluated using binaural recordings inside three aircrafts of different sizes during regular flights. The parameters of sharpness, tonality and loudness, which are expected to be correlated with perceived sound quality, were calculated. The results of listening tests performed with or without loudness equalization were obtained applying the paired comparison technique. These results will be discussed in detail in this paper.
