Abstract
A device determines the propagation time of an acoustic signal by cross-correlation analysis between a transmission signal and a reception signal. The device determines the propagation time by cross-correlation analysis between the transmission signal and the reception signal from which reverberation has yet to be removed, removes, from the reception signal, as the reverberation, a signal component at and after a time point based on the determined propagation time, and redetermines a propagation time by cross-correlation analysis between the transmission signal and the reception signal from which the reverberation has been removed.
