Document Type and Number:
WIPO Patent Application WO/2024/010366
Kind Code:
A1
Abstract:
The present invention relates to a space monitoring system and space monitoring method using an acoustic signal. The present invention provides a technology enabling easy, prompt, and accurate determination of a situation of a space to be monitored, through comparison, in units of individual frequencies or units of frequency intervals, between frequency response spectrums for each measurement period for the space to be monitored, and analysis of a change degree and a change pattern of difference values of the comparison.
