Title:
SILENCER FOR PLAYBACK SOUND FIELD
Document Type and Number:
WIPO Patent Application WO/1989/000800
Kind Code:
A1
Abstract:
A silencer to be disposed near a listener (primarily his head) in a playback sound field. The silencer consists of a silencing member and a support member, and provides body sensing vibration similar to that of a real sound source by making variable the ratio of a sound pressure applied to the external auditory meatus to a sound pressure travelling to the body. The head reflection sound generated at the head of the listener is damped by the silencing member disposed near the head (damping can be made irrespective of the difference in the head shape of an individual). Thus, the present invention can improve the transmission characteristics at the time of playback and provides high-fidelity playback (e.g. playback by binaural speakers).
