<P>PROBLEM TO BE SOLVED: To provide a high presence sound listening apparatus which enables high presence sound listening equivalent to a binaurally recorded sound source, in spite of using a sound source which is not recorded binaurally. <P>SOLUTION: The high presence sound listening apparats is equipped with a sound-source presentation section S, a sound collection section R, and a sound presentation section H. The presentation section S has a speaker 1 which is arranged in a sound-isolated case 2 and is positioned at an arbitrary position inside the case 2. The collection section R has a dummy head 3 which has a head part transfer function approximate to the head part transfer function of a listening person 10, is driven so as to follow up the movement of the head part of the listening person 10 synchronously, has microphones 4a, b at the positions of both ears, and is arranged similarly in the case 2. The presentation section H has a communication section 5 for transmitting acoustic signals obtained by collecting sounds reproduced and radiated from the speaker 1 with the microphones 4a, b arranged at the positions of both ears, and a headphone 6 to which the transmitted acoustic signals are entered to reproduce and output the sounds. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
