That is an interesting question. I would recommend the following 
papers; Anyone know of any other relevant ones?

evidenced by electrophysiological versus psychoacoustical measures
Author(s): Zhou JX, Durrant JD
Source: JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 114 (3): 1508-1515 
SEP 2003

Title: THE COMBINATION OF INTERAURAL INFORMATION ACROSS FREQUENCIES - 
LATERALIZATION ON THE BASIS OF INTERAURAL DELAY
Author(s): DYE RH
Source: JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 88 (5): 2159-2170 
NOV 1990

Sens Processes. 1976 Dec;1(2):109-26.	
Critical band in auditory lateralization.
