Comparison between objective & perceptive measurements for room acoustic predictions Abstract
Summary
Great importance of good acoustical conditions in rehearsal room
Results show good correlation between perceptual and objective measurements
No guidance of operations for design
The relation between requested acoustic characteristics and design issues leads to the modeled design witch results are good compared to expected ones.
This is the study of relocation of La Sirene de Paris
