Subject: : Sound Source Segregation and head motion From: Pierre Divenyi <pdivenyi(at)EBIRE.ORG> Date: Sat, 17 Dec 2005 08:35:43 -0800--=====================_19680859==.ALT Content-Type: text/plain; charset="us-ascii"; format=flowed Head motion temporarily changes a stationary source into a moving object. In the early 90's, Chandler and Grantham showed that the detectable angle of a moving object is inversely proportional to its bandwidth. In a theoretical paper** we showed that this trade-off is a property of physics -- in other words, motion changes spectral resolution and vice-versa. Consequently, by moving his/her head the listener can introduce subtle spectral cues that could be potentially useful for disambiguating spectral grouping of one or more simultaneously present sources.
