Re: auditory localization

EM and list,

        A statistical model indicating the consequences of varying the
number of sources and their separation in a source identification
experiment appears in JASA vol 104, pp 3546-3557 (1998). It includes
references to earlier work that may also be of interest.


Best,
Bill Hartmann
