<p>A reverberation suppression device includes a first storage unit (101) configured to store, in advance, information representing a first impulse response obtained from a signal output from a microphone (104) when a sound source positioned according to directivity of either a speaker (106) or the microphone, which are mounted on a mobile terminal (100), outputs an impulse; a second storage unit (102) configured to store information representing a second impulse response obtained from a signal output from the microphone (104) when the speaker (106) mounted on the mobile terminal outputs an impulse in a room where reverberation sound is to be suppressed; a response correction unit (103) configured to obtain a corrected impulse response, which reflects the room's environment, by correcting the second impulse response, which is represented by the information stored in the second storage unit (102), using the information representing the first impulse response; and a sound correction unit (110) configured to correct a sound signal.</p> |
