A Facility for Simulating Room Acoustics, Employing a High Density Hemispherical Array of Loudspeakers

摘要

Over the past 50 years, upper hemisphere immersive loudspeaker systems in anechoic environments have supported research into the perception of room acoustics. A newly completed laboratory facility consisting of an upper hemisphere 196-loudspeaker array is described, along with available methods to deploy room acoustics auralization within the facility. With a mean interval of 11.5. between adjacent loudspeakers, spatially quantized discrete loudspeaker rendering has significant potential as an audio rendering technique, possibly used in combination with other methods.
