Does virtual concert hall color affect loudness ?
Résumé
Being a multi-sensory experience, the perception of a musical performance can be affected by many factors, especially auditory and visual ones. Studies have found connections between various visual factors and room acoustic perception, notably for spatial attributes like room size and source distance. The influence of color on perceived loudness has been found in studies of vehicle noise. To examine whether the same effect happens in concert halls, this study used a virtual reality model of a small concert hall (or recital hall) of various colors to present visual and auditory scenes, and participants rated the loudness and reverberance of an auralized string quartet. Results indicate that the effect of color on loudness and reverberance ratings very weak in comparison to varying sound strength (G) by up to 6 dB, or varying reverberation time by a factor of up to 1.5.
