Abstract
- The aim of this study is to explore the performance of binaural and monaural recordings in soundscape evaluation. Twelve sites with different acoustic scenarios were chosen, where binaural and monaural recordings were simultaneously made. Nine soundscape indicators were assessed by residents through a laboratory-based auditory test. The results showed that the two recording methods present good agreement on most soundscape evaluation indicators including overall impression, acoustic comfort, pleasantness, annoyance, eventfulness, and loudness. The two recording methods were found to be correlated with different indicators in a similar way. For most sites, the two recording methods were significantly correlated excluding for directionality. For both recording methods, the A-weighted sound pressure level was found to have a weak impact on soundscape evaluation. Reverberation time significantly affects reverberance through binaural recordings. Overall, for most soundscape indicators, it is feasible to use both recording methods, although when "realism," "reverberance," and "directivity" are involved in evaluation, binaural recordings will render corresponding perception more consistently than the monaural.
