<P>PROBLEM TO BE SOLVED: To provide an individual acoustic environment having presence while reducing sound leakage from the other seat. <P>SOLUTION: An acoustic system uses a self speaker installed at the rearward of a listener in a first individual space and an error microphone installed to be closer to the listener than the self speaker, and constituted so that a sound-leakage reduction filter generates a control sound for a negating sound leaked from the other speaker installed in a second individual space to the first individual space on the basis of a leak sound transfer function between the other speaker and the error microphone and an error path transfer function between the self speaker and the error microphone, and provides the generated control sound to the self speaker, a virtual sound-source filter generates a virtual sound source which is a provided sound with a sound image arranged in front of the listener, and a rear-sound-source inverse filter corrects the rearward localization of a sound image formed by the reproduction of the virtual sound source by the self speaker toward the listener. <P>COPYRIGHT: (C)2009,JPO&INPIT |
