Abstract :
In order to develop a new human perception inspired process useful for underwater acoustic signal processing, the purpose of this paper is to present a new human physiology based time-frequency representation. This method is based on the use of the Mel filters, classicaly used for the voice recognition. Several experimentations on real underwater signals are presented and discussed.
