Re: Integration of ITD information

[Erick Gallun <gallun@xxxxxx>]

I agree with David that the specific answer to your question appears 
in Dye, 1990.

For a good summary of the phenomenon and a very nice model, look at

Stern R. M., Zeiberg A. S., and Trahiotis, C. (1988) "Lateralization 
of complex binaural stimuli: A weighted-image model "J. Acoust. Soc. 
Am. 84, 156

A very clear equation for predicting how information is combined appears in

Buell, T.N and Hafter, E. R. (1991) "Combination of binaural 
information across frequency bands" J. Acoust. Soc. Am. 90, 1894

However, the most recent word on the subject of that equation appears in

Bernstein, L. R., and Trahiotis, C. (2004). "The apparent immunity of 
high-frequency
"transposed" stimuli to low-frequency binaural interference," J. 
Acoust. Soc. Am. 116, 3062
