Abstract:
Disclosed are a device and a method for tracking a sound source location by removing wind noise. The disclosed method for tracking a sound source by removing wind noise comprises the steps of: performing a Fourier transform for input signals of a time domain received by a plurality of microphones; detecting a first sound source section on the basis of an average power value of the Fourier-transformed input signals; detecting a second sound source section from which wind noise has been removed, on the basis of the first sound source section and a difference of power values of the input signals received by the microphones; and detecting a location of a sound source on the basis of the second sound source section and a phase difference of the input signals received by the plurality of microphones.
