Effects of binaural sound presentation on listeners' assessments in a product sound task and problems of today's measurement procedures

摘要

Today, binaural sound measurement and reproduction methods are already widely used for the assessment of product sounds in listening tests. But the respective instrumental measurement devices mostly still treat binaural recorded signals separately as two monaural ones rather than integrating them. Due to the fact that most instrumental evaluation methods do not take into account binaural differences, the assumption arises that errors occur between instrumental and human assessments. This assumption was investigated in a listening test on interior car sounds where listeners had to assess the sounds according to given verbal attributes. Significant differences in the results of the assessment for binaural and monaural presentation could be shown for some verbal attributes.
