   Author : Crispin Dickson; Shafiquzzaman Khan; Mendel Kleiner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paired comparison; sorting based paired comparison; sorting algorithms; mergesort; quicksort; aircraft sound synthesis; aircraft noise; sound quality; tonal effects; angle positions; flight conditions; methods of equalization; cognition; Acoustics; Akustik;

   Abstract : A few aspects of aircraft noise were evaluated. These were (i) methods of subjective evaluations, (ii) effects of equalization and (iii) the effects of cognitive aspects.In the first paper, sorting algorithms were used instead of conventional paired comparison method in order to reduce the number of pairs in the evaluation of subjective judgments.

4. 2. Auralisation of airplanes considering sound propagation in a turbulent atmosphere

   Author : Frederik Rietdijk; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auralisation; Aircraft noise; Outdoor sound propagation; Atmospheric turbulence;

   Abstract : Aircraft noise is a major issue in urban areas. Due to a rising level ofurbanisation and the continuing growth of air traffic more people are exposed toaircraft noise than ever. Methods currently used for assessing theimpact of aircraft noise on humans consider mostly energetic quantities, and not thedynamic character of the sound. READ MORE
