Sound field production apparatus

摘要

The present invention provides a sound-field production apparatus comprising a direct-sound-generating means for generating a direct sound from a sound signal supplied to the direct-sound-generating means and a reflected-sound-generating means for generating a sound serving as a substitute for a sound obtained as a result of reflection of the direct sound at a level lower than the direct sound with a timing lagging behind the direct sound from the sound signal supplied to the reflected-sound-generating means. The sound-field production apparatus makes it possible to reproduce an impressive sound field that gives a better feeling of presence on the scene as a sound field in a movie theater or the like does by creating a sound-field space having an effect of sound-image broadening.
