Abstract
The present invention provides a sound field correcting system and a reverberation adjusting apparatus capable of correcting a reverberation time characteristic by an easy operation without setting a complicated parameter. A surround systemhas a sound reproducing apparatusfor adjusting a reverberation component of sound on the basis of a reverberation characteristic of a listening roomand amplifying the sound by a speaker system; and a microphonefor collecting the amplified sound in a specific listening position in the listening room. The sound reproducing apparatusincludes: a test signal generating devicefor generating a test signal; a space characteristic analyzerfor recognizing an attenuation characteristic indicative of attenuation with time in the listening room on the basis of the obtained amplified test signal, and calculating attenuation time in the listening position of the amplified sound on the basis of the recognized attenuation characteristic; and a signal processorfor adjusting the reverberation characteristic of the listening room
