Re: auditory stochastic resonance demos?

Hi Dan,

We have found a stochastic resonance-like effect in MSO neurons and models.

The effect differs from the classical amplitude-based effect.  These neurons and models are slope or ramp-detectors.  Noise can enable them to respond to slopes that too slow for them to notice in the absence of noise.   We call the phenomenon:  slope-based stochastic resonance. 

So far we don't have a behavioral demonstration.

  Does anybody have any demos of stochastic resonance effects in audition?  For example, adding noise to a below-threshold song or speech and having it then become audible?
