Re: [AUDITORY] Sound example for spectral smearing

[ngrimault <nicolas.grimault@xxxxxxx>]

Dear List,

We have recently developed a Hearing Loss Simulator that is fully 
down-loadable as an open source project.

The concept, based on the work of Irino, Patterson and colleagues, is an 
inverse dynamic gammachirp auditory filter that cancel compression using 
an inverse High Pass Auditory filter and, as a consequence, reduce the 
audibility, linearize the IO function of the cochlea and increase the 
bandwidth of the auditory filters for a normal hearing listener.

This hearing loss simulator has already simulated successfully the 
decrease in Speech Reception Thresholds for HI liseners:
