- Title
NOTE ON THE APPLICATIONS OF A SIMPLE ACOUSTIC IMMERSION INDEX.
- Authors
Hough, Cameron M.
- Abstract
The applicability of a simple acoustic immersion index for halls is investigated by calculating the values of the index for many well-documented halls and theatres. Correlations between the immersion index S1 and other auditorium acoustic parameters are investigated, as well as the effectiveness of the index in describing subjective evaluations of halls. The index S1 appears to broadly correspond to subjective ratings of halls, both from published data and from experiences in Australian halls, but is only weakly correlated with technical parameters describing the immersion of the sound field. However, the index appears to be reasonably correlated with Binaural Quality Index (BQI), and therefore may be useful as a "spaciousness index" as a means of estimating BQI during the early design of a hall.
