Abstract
Disclosed herein are an artificial ear and a method for detecting the direction of a sound source using the same. The artificial ear includes a plurality of microphones; and one or more structures disposed between the plurality of microphones. In the artificial ear, the amplitudes of output signals respectively inputted to the plurality of microphones are designed to be different based on the direction of a sound source. The method for detecting the direction of a sound source includes receiving output signals with different amplitudes from a plurality of microphones; determining front-back discrimination of the sound source from a difference between the amplitudes of the output signals of the microphones; and determining an angle corresponding to the position of the sound source from a difference between delay times of the output signals of the microphones.
