Abstract

The ultimate goal of the research is to propose an acoustic measure of perceived clarity for small spaces such as studio control rooms and listening rooms. While C80 is somewhat successful in predicting the perceived clarity of sound in performance spaces, detailed research of clarity in small spaces has not been conducted. An experiment was conducted to investigate the perceived clarity of reproduced sound in small spaces with a focus on the arrival direction and delay time of the first reflections. Seven participants were asked to evaluate the sounds with loudspeaker simulated wall reflections in author-constructed temporal quasi-anechoic chamber. Variation of the first reflections did significantly influence perceived clarity and spatial impressions such as ASW, LEV, and spatial definition.
