ADAPTIVE SOUND GENERATOR BASED ON AN AUDIENCE POSITION TRACKING TECHNIQUE

摘要

PURPOSE: An adaptive sound generation with a listener location tracing technique is provided to acquire location information of a listener which is strong in noise characteristics using an energy detector. CONSTITUTION: A listener location tracing part(100) obtains location information of a listener by a sound signal which is created from the listener by a multi-channel microphone. A sound compensating part(200) obtains general sound from a separate instrument. The sound compensating part creates a sound in which space perception of listener is compensated according to the location of listener using the location information of listener and a head-related-transfer-function. The listener location tracing part comprises the multi-channel microphone(10) which obtains the sound signal generating from listener. The listener location tracing part comprises a sound detector(20) detecting the sound signal entered from the multi-channel microphone and a location estimator(30) which producing the location information of listener by a detected sound signal.
