Abstract

To explore the acoustic environment of sequential spaces, the paper discusses the correlations between sound level and five independent dimensions of acoustic environment including loudness, intimacy, reverberation, clarity and spaciousness. Two sequential spaces with similar spatial composition were selected for questionnaire survey and field measurement. The results showed that under the condition of no sound source, sound level only affected loudness. Under the condition of sound source, a higher sound level resulted in a higher loudness, reverberation and spaciousness. Sound level differences between the rooms did not necessarily correspond to assessment difference in these three indicators. Intimacy was negatively correlated to clarity, and there was a threshold of sound level difference related to assessment difference of these two indicators.
