To provide a sound collection reproduction device which can drastically reduce mistakes of before and after a sound image, and which allows an operator to understand a reproduced sound image outside a vehicle, in addition to visual confirmation.SOLUTION: A sound collection reproduction device includes: three or more microphones 2a-2d placed outside a vehicle and having directivity for collecting the sound outside the vehicle; three or more binaural transducers 5a-5d provided corresponding to the three or more microphones, and converting the sound outside the vehicle, which is collected by a corresponding microphone, into binaural sound of the sound image direction corresponding to the orientation direction of the microphones; a binaural sound synthesis section 6 for synthesizing three or more binaural sounds converted in the three or more binaural transducers and a stereo sound of a sound source; and a signal reproduction section 7 for reproducing the binaural sounds synthesized in the binaural sound synthesis section and the stereo sound of the sound source.SELECTED DRAWING: Figure 1
【課題】音像の前後間違いを激減でき、運転者が目視確認に加えて車外の再生音像を把握できる収音再生装置。【解決手段】収音再生装置は、車両外に配置され、車外音を収音する指向性を有する3個以上のマイクロフォン2a〜2dと、3個以上のマイクロフォンに対応して設けられ、対応するマイクロフォンで収音された車外音を当該マイクロフォンの指向方向に対応した音像方向のバイノーラル音に変換する3個以上のバイノーラル変換部5a〜5dと、3個以上のバイノーラル変換部で変換された3個以上のバイノーラル音と音源ソースのステレオ音とを合成するバイノーラル音合成部6と、バイノーラル音合成部で合成されたバイノーラル音と音源ソースのステレオ音とを再生する信号再生部7とを備える。【選択図】図1
