METHOD AND DEVICE FOR ESTIMATING SOUND SOURCE DIRECTION

摘要: PROBLEM TO BE SOLVED: To provide a new method and device for estimating sound source direction which require less calculation accuracy hardware of small scale. SOLUTION: A comprises plurality code/time series generating parts 7 8 extract the audio signals obtained by microphones 1 2 polarities these according to at ratio one one, respectively, an inter-correlated function part 9 receives all outputs from calculates inter-correlation, normalized power 10 power, time average averaged value, detector 12 estimates based on output part.
