Group Listening Tests for Measuring Soundscape Evaluations under Laboratory Conditions
* Presenting author
Abstract:
Psychoacoustic listening tests are widely used to obtain subjective ratings for sounds under laboratory conditions. In this context, the annoyance of road traffic noise was often investigated. Furthermore, the assessment of soundscapes by interviewing people recently gained attention as the perception of acoustic environments cannot simply be predicted using sound levels. Up to now, these interviews have been carried out directly at the locations of interest. Binaural and monaural recordings are also made following ISO/TS 12913-2:2018 to capture the acoustic environment. In addition to analyzing the recordings to extract psychoacoustic parameters, binaural measurements can also be used for listening tests. The simultaneous questioning of several test persons has a high potential for collecting large data sets, especially for soundscapes where there are not enough people on-site. As part of this project, a methodology for conducting group listening tests was developed and tested using a pilot study. The comparison between on-site surveys and group listening tests reveals whether the subjective evaluations are reproducible with binaural recordings and pictures.
