SYSTEM AND METHOD FOR DETERMINING OCCUPANCY

A method of detecting occupancy in an area includes obtaining, with a processor, an audio sample from an audio sensor and determining, with the processor, feature functional values of a set of selected feature functional values from the audio sample. The determining of the feature functional values includes extracting features in the set of selected feature functional values from the audio sample,and determining the feature functional values of the set of selected features from the extracted features. The method further includes determining, with the processor, occupancy in the area using a classifier based on the determined feature functional values.
