The overall goal of the project is to better understand how people subjectively perceive differences in concert hall acoustics. Subjects will listening to musical passages, side-by-side, in aural simulations of being in different concert halls or rooms. Subjects will then be asked to provide perceptual ratings on reverberance about the different rooms in which they are listening to. The results from this research will help to better understand how concert-goers perceive different room, and will help acoustic consultants to better design concert hall in the future to produce more pleasing acoustic environments.
