ABSTRACT:
A first signal processing section is used to constitute an impulse response of a head related transfer function region contributing to position recognition of a virtual sound source. A second signal processing section is used to realize an impulse response of a reflected sound region contributing to a sense of distance of the virtual sound source. A rotational angular speed sensor and a response characteristic control section are used to recognize position changes of the listener's ears. By controlling the first signal processing section, the sound image is localized with sufficient feeling of distance at an arbitrary position while suppressing signal processing operation quantity of the impulse response corresponding to the transfer function from the virtual sound source to both ears, and the position of the virtual sound source can be changed in correspondence with a change of position of the ears of the listener.
