¿µ¹®³»¿ë¿ä¾à | In this contents, the definition of acoustic intrusion detection sensor system is
explained firstly, and the measuring method of sound field change induced by an intrusion object with a sound generating speaker and microphone array. Finally, the evaluation index for the quality of acoustic intrusion detection sensor system is defined from the ratio between the sound field change signal and noise level. |
