Towards a model for discrimination of broadband signals
N. I. Durlach, Louis D. Braida, Yoshiko Ito · The Journal of the Acoustical Society of America · 1986
The conventional model for broadband discrimination assumes that resolution is limited by peripheral internal noise that is statistically independent across channels. In this paper, we extend this model in a number of directions. In particular, we compute, compare, and discuss the effects of interchannel correlation and central noise on the sensitivity index d', for discrimination of overall level and discrimination of spectral shape.
