Abstract
A directional acoustic sensor may include a plurality of resonators arranged in different directions; and a processor configured to calculate a time difference between a first signal that is received by the plurality of resonators directly from a sound source (e.g., a speaker) and a second signal that is received by the plurality of resonators from the sound source after being reflected on a wall surface around the sound source, and determine a distance between the sound source and the directional acoustic sensor based on the time difference.
