Abstract: In large interior spaces, the attenuation of sound energy in the indoor sound field is different from that of the conventional sound field. This study aimed to explore the characteristics of the indoor acoustic environment in large-space buildings through field measurements and a questionnaire. The indoor acoustic environments of eight large space buildings in three categories were investigated. The results revealed that large-space buildings with different functions have both different and similar characteristics in terms of the subjective evaluation of the acoustic environment. However, it is not ideal overall and needs further improvement. Traffic buildings and sports buildings should focus on the improvement of acoustic concordance, while spatial impression should be taken into consideration for exhibition buildings. These findings provide theoretical guidance for the acoustic design of different functional large space buildings.
