A sound signal following control of a mobile robot with the estimation of the sound source location has been implemented in this research using a microphone array. The geometry of the microphone array and the traveling time difference of the sound signal depending on the distance provides the two dimensional coordinates of the sound signal. To detect the same transmission moment of the sound signal,...
In this paper, the de-noising filter study of the sound-source using the DWT is introduced. We suggest the de-noising filter using the Discrete Wavelet Transform (DWT). The DWT has been performed to remove out the noises from the signals. In order to confirm the performance of suggested filtering algorithm, we estimate the distance and angle from the microphone to the sound-source and compare the...
