A howling suppression device includes a first speaker and a second speaker provided in a room, and a sound signal generator configured to supply the first speaker with a first sound signal generated based on an output signal of a microphone, and configured to supply the second speaker with a second sound signal generated so that a part or all of a sound emitted from the first speaker is canceled out at the microphone by a sound emitted from the second speaker based on the output signal of the microphone.
