Abstract: The author of this paper analyzed potential possibilities of human presence detection inside a room based on determining the change in total sound absorption. The change between sound absorption with and without human leads to determine person presence. Limitations of this method were examined: in case of human presence, the change of reverberation time must be greater than measurement uncertainty. Important parameters are a volume of a room, total sound absorption, a frequency characteristic of the measurement signal, signal to noise ratio, etc. These parameters are criteria for assessing the reliability of the detection. Different types of measurement signals and systems were considered and tested. The aim was a maximum simplification of measurement method while keeping the minimum measurement uncertainty.
