PURPOSE:To eliminate such a phenomenon that a voice sounds doubly while being separated in a direct sound and a reverberation sound and gives a strange impression apart from the original voice by providing one or plural intermediate reverberation signal generating circuits to give an original signal a delay time shorter than that given by a reverberation signal generating circuit. CONSTITUTION:The original signal outputted form an acoustic source 1 goes through a pre-amp. 2 and a main amp. 7, and is reproduced by a direct-sound speaker 8. The original signal also is branched from the output-side of the pre-amp. 2, and inputted to the reverberation signal generating circuit 4, the first and second intermediate reverberation signal generating circuits 9 and 10 and is given respective delay times to be reproduced by corresponding speakers 13, 16, and 18. Between the direct sound reproduced by the speaker 8 and the reverberation sound generated by the speaker 13, the continuity of sound is generated by the intermediate reverberation sound reproduced by the first and the second intermediate reverberation sound speakers 16 and 18. As a result, the reproduced sounds from respective speakers 8, 13, 16, and 18 are sensed as an integral hybrid sound. |
