Acoustic source localization for design of tangible acoustic interfaces

Abstract

Acoustic source localization is important for the design and implementation of intelligent environments such as computer–human interaction systems. This chapter discusses different methods for multiple source localization and presents a comparison among them. It also presents the mathematical model of the method based on steered response power - phase transform (SRP-PHAT) algorithm for multiple sources localization under reverberant conditions. The PHAT are applied to suppress the reverberation from the environment. Global searching method and clustering technique are used to find the positions of multiple sources. MATLAB simulations and practical tests are carried out under real reverberant conditions. The simulation and test results show that the method is suitable for two acoustic source localization in a reverberant environment.
