Abstract
An audio signal high frequency component controlled in terms of directivity is reproduced, or an audio signal high frequency component compensated in terms of frequency characteristic or controlled in terms of directivity is reproduced, such that the reflected sound comes from a direction in which the high frequency component is intended to be localized. The sound pressure in a seat where a desired localization effect is not provided due to the arrangement of speakers is compensated such that the interaural amplitude level in the seat is equal to that of another seat. Thus, an equivalent level of localization effect is provided in a plurality of seats, especially for an audio signal high frequency component, without significantly increasing the number of the speakers.
