Development of a system for location finding of low-level sound source by using human acoustic system with stochastic resonance

The purpose of this study is to develop a system that enables location finding of a small sound. The system is composed of a biologically-inspired system which uses a hearing mechanism based on the human ear and a mechanism for perceiving weak signals that uses stochastic resonance. Using this proposed system, we implemented the location finding of small sounds through numerical simulations and hardware experiments. Good results were obtained for the small sound source location finding.
