In-air passive acoustic source localization is important to the design and implementation of tangible acoustic interfaces for computer human interaction. The methods used for in-air passive acoustic source localization are discussed in this paper. A time delay estimation method based on general cross-correlation was chosen for the application. In addition, a phase transform and smoothed coherence transform are combined to suppress the reverberation and background noise from the environment. MATLAB simulations and practical ...
