Abstract
A process for evaluating spatial impression of an enclosed space includes the steps of generating output signals as a function of fluctuating sound pressure at two points spaced about one-quarter meter apart, band limiting the output signals to a pass band of less than about one octave, generating fluctuating signals that represent amplitude information of the band limited output signals, band limiting the fluctuating amplitude information signals to a pass band of about five hertz to thirty hertz, and comparing the band limited fluctuating amplitude information signals to provide an indication of the spatial impression of the enclosed space.
