摘要
The present invention relates to a method for detecting changes in an indoor space environment, an apparatus and a computer program for detecting changes in the indoor environment therefor, based on an active sound signal generated based on a reflection wave for a sound wave signal propagated to an indoor space and noise generated in an indoor space We propose a method to detect environmental changes in the indoor space by identifying the total amount of airflow and airflow pattern in the indoor space by using the passive sound signal generated by .
