声音再现装置和声音再现方法
Sound reproduction apparatus and sound reproduction method
US-8027476-B2用于提供声音定位感的音频再现设备。
专利摘要
提供一种能够通过使用标准头相关传递函数向听者提供目标声音定位感的声音再现装置。在麦克风放大部中,从仿真头麦克风输入的左拾音信号和右拾音信号的高频分量仅由延迟电路延迟。因此,由于个体差异小的低频分量的再现声音可以更早输出,再现声场空间中的听者可以通过较早到达的低频分量的再现声音感知声音定位感。结果,即使使用标准头相关传递函数,也能够使再现声场空间中的听者感知目标声音定位感。
Original abstractA sound reproduction apparatus capable of providing a target sensation of sound localization to a listener by using a standard head-related transfer function is provided. In a microphone amplifying section, only the high frequency components of a left sound pickup signal and a right sound pickup signal, which are input from a dummy head microphone, are delayed by a delay circuit. Consequently, since the reproduction sound of the low frequency components having small individual differences can be output earlier, a listener in a reproduction sound field space can perceive the sensation of sound localization by the reproduction sound of the low frequency components that arrive earlier. As a result, even when a standard head-related transfer function is used, it becomes possible to enable the listener in the reproduction sound field space to perceive the target sensation of sound localization.
