Abstract
Acoustic outputs from an audio system and various acoustic output devices are produced from a speaker, and a sound which a user desires to hear clearly is automatically selected and corrected with emphasis. A TV sound, an acoustic guide of a navigation system, and a sound on the other end of a hands-free device are delivered to a selector, and one of them is selected by a selector switching control and corrected by an acoustic correction filter to be produced. The other acoustic signals are produced as non-correction target signals together with an audio signal. An acoustic output processing control unit performs operational control of acoustic output processing corresponding to an operation mode of an acoustic output device and a present mode of acoustic output processing detected by device operation-mode detecting means while performing various operational function controls, including selector switching control and buzzer control, corresponding to data obtained by reading a memory in which modes of acoustic output processing are stored in advance.
