摘要

The present invention relates to security systems and invasion determination method. A kind of relationship of the particular space of sound file, measurement flow through the sound generating apparatus of sound source and are obtained from sound level measurement equipment, and there are the sound fields of sound field and change that intrusion target is initially determined that in particular space by using difference. Security system according to the present invention includes sound source generating means, and for generating sound source, sound level measurement equipment is formed for measuring sound field by sound source. The generation of system detection invasion, by comparing the surveyed acoustic domains of originally determined sound field. ;The 2016 of copyright KIPO submissions
