Document Type and Number:

Japanese Patent JP7063714

Kind Code:

B2

Abstract:

A position estimation device according to the present invention is provided with: an arrival time estimation unit for acquiring a waveform signal of a sound detected by a sensor, estimating a detection start time or a detection end time of the sound on the basis of the waveform signal, and estimating a time of arrival of the sound at the sensor on the basis of the detection start time or the detection end time; and a position estimation unit for estimating the output position of the sound on the basis of a time difference in times of arrival of the sound at a plurality of sensors, estimated by the arrival time estimation unit.
