Abstract:

A vehicle−mounted stereophonic sound field reproducer for reproducing a stereophonic sound field abundant in the feeling of presence for each seat comprises at least two speakers disposed to produce a stereophonic sound field reproduction space in a region including the left and right external ears of a seated listener, and a stereophonic signal processing means for converting the output signal from a sound source into a stereophonic sound field signal and feeding it to the respective speakers. A Vehicle−mounted stereoponic sound field silencer has an opposite phase signal generating means for supplying the stereophonic signal processing means with a silencing signal so as to suppress sound for each seat without having any effect on other seats.
