Sound reproduction apparatus and sound reproduction method
US-8027476-B2Abstract
A 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.
