At the Applied Psychology Unit, we have developed a time-domain model of auditory processing to simulate the auditory images produced by complex sounds. The NAP includes the phase-locking information encoded by the inner haircells because it is assumed that this information plays an important role in auditory perception and speech perception. There are now a number of ways to produce auditory images, and in October 1995, we published a short paper describing a software package that we use to assemble and run different forms of Auditory Image Mode. You can read about AIM and view a couple of auditory images on our WWW page. Alternately, you can click here to access the AIM page.

A pulse ribbon model of monaural phase perception. APU report 2341. The construction of auditory images begins with a spectral analysis performed by the cochlea on the incoming sound. In the auditory model, this process is simulated by a bank of auditory filters. The following publications describe the progressive development of a technique for measuring the shape of the auditory filter in humans.
