ARTIFICIAL EAR AND METHOD FOR DETECTING THE DIRECTION OF A SOUND SOURCE USING THE SAME

摘要

PURPOSE: An artificial ear and a sound source direction detecting method using the same are provided to reduce amount of output signals to be processed by freely arranging microphones at a platform. CONSTITUTION: An artificial ear includes two microphones(301,302) having different channels and a structure(303) arranged between two microphones. The structure can cause differences of the output signals inputted into the two microphones. The output signals inputted to the two microphones emits at the direction sensing target sound source. The structure can be designed like human's earflap. The front direction and the back direction can be easily discriminated via the differences of the output signals.
