ABSTRACT:
Disclosed herein is an acoustic correction apparatus and method for vehicle audio systems which is capable of providing optimal sound at a reference level to a listener even though the acoustic spatial response characteristics in the room of a vehicle vary due to a change in the material of seat covers or the like. A first acoustic analysis unit obtains target frequency characteristic data at a specific listening location based on generated acoustic signals played from an audio system. A second acoustic analysis unit obtains measured frequency characteristic data at the listening location based on measured acoustic signals collected by the microphone unit. An acoustic correction unit adjusts the equalizer of the audio system based on the target and measured frequency data.
