The Influence of Early Sound Direction on Apparent Source Width (ASW)

Abstract:

t is now generally accepted that there are two spatial effects in concert halls: apparent source width (ASW) and listener envelopment (LEV). Barron have proposed the early lateral sound energy fraction (LF_E) as an objective measure for apparent source width. But this measure takes no account of asymmetry role between the early sounds from front and behind. The purpose of this study is to investigate the relation between the arrival direction of early sound and ASW. Experiments using sound field simulated in an anechoic room confirm that early-arriving sound from in front of listener give more contribution to ASW than symmetrical direction behind listener. As the direction of arrival approaches between 45o to 60o from straight ahead in the horizontal plane the ASW approaches a maximum.
