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 system100has a sound reproducing apparatus120for adjusting a reverberation component of sound on the basis of a reverberation characteristic of a listening room10and amplifying the sound by a speaker system130; and a microphone140for collecting the amplified sound in a specific listening position in the listening room10. The sound reproducing apparatus120includes: a test signal generating device124for generating a test signal; a space characteristic analyzer127for 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 processor200for adjusting the reverberation characteristic of the listening room10.
