A Miniature Acoustic Sensor that Mimics Mammalian Sound Processing

Abstract

We are developing a miniature acoustic sensor that contains mechanical and electrical counterparts to the auditory processing subsystems used by mammals. The overall plan is to mimic the mammalian processing scheme, eventually to the point of achieving mammal-like recognition of auditory objects. The expected device is currently in development stages. The device is envisioned to consist of a mechanical frequency analysis stage, a subsystem for extracting both envelope and temporal information and converting analog information to events, and a digital subsystem that extracts features. Features currently slated for extraction are pitch and bearing, however the entire feature extraction subsystem is designed in a way that is amenable to modification for enhanced capability.
