The measurement of temporal stream of hearing by continuous judgments. In the case of the evaluation of helicopter noise

Abstract

In our daily lives we are surrounded with a variety of sounds which vary with time and spread in space. The configurations of sound along the temporal stream have the meaning. The meaning will be destroyed if these sounds are divided into short segments as used in conventional methods. The method of continuous judgment by category and the method of continuous judgment by selected description have been developed for examining the impression of temporally varying sounds along the temporal stream. In this paper these methods are introduced with their procedures and applications to the evaluation of helicopter noise. © 1993, Acoustical Society of Japan. All rights reserved.
