Abstract
Subjective perception in the realm of concert hall acoustics, specifically overall impression, is a difficult problem to approach. Ideally, this type of work should be done using realistic concert hall auralizations, allowing direct comparison of a wide variety of rooms from around the world. Currently, measurements are being taken in concert halls across the United States and in Europe. Halls to be measured were selected from an online survey of researchers and consultants around the United States and Europe. Final selections were made to ensure that a wide variety of hall shapes, sizes, and reverberation times were included in the database, given the available travel resources. Measurements have been made using a 32-element spherical microphone array, a three-way omnidirectional sound source, and a directional sound source. The directional sound source is a 20-element compact array that can reconstruct the frequency-dependent radiation patterns of different orchestral instruments. An overview of the halls included in the database and measurement results will be presented to illustrate the variety within the database. As well, plans for upcoming subjective testing to piece-apart the perception of preference in concert hall acoustics, considering both the hall and individual taste, will be discussed.
