<P>PROBLEM TO BE SOLVED: To provide an acoustic reproducing apparatus capable of providing a sense of target sound image localization to a listener by using a standard head transmission characteristic. <P>SOLUTION: In a microphone amplifier unit 40 in a sound collecting block, only the high frequency components of a left collected sound signal SL1 to be inputted from a dummy head microphone 13 and the high frequency components of a right collected sound signal SR1 are delayed by a delay circuit 42. In this case, since reproduced sounds of low-frequency components less influenced by individual difference are previously outputted from speakers 46, 47 of reproduced blocks, a listener U in a reproduced sound field space 45 can feel a sense of sound field localization by the reproduced sounds of low-frequency components which previously arrive. Thus, even if the standard head transmission characteristic is used, it is possible to cause the listener U in the reproduced sound field space 45 to feel the sense of target sound field localization. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
