Title:
SOUND VOLUME CONTROL DEVICE, SOUND VOLUME CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/011923
Kind Code:
A1
Abstract:
A sound volume control device is connected to output units disposed with left-right symmetry in relation to the position of two seats on the left and right in a mobile body. The sound volume control device estimates a shared frequency to be controlled when audio outputted from each of the output units is listened to in the listening positions of each of the two seats on the left and right, and corrects the level of the frequencies on the basis of the shared frequency. Preferably, the frequency at which the direct sounds of the audio outputted from each of the output units have the same phase at the listening positions of each of the two seats on the left and right is determined to be the shared frequency, on the basis of the distance from each of the output units to the listening position of one of the two seats on the right and left.
