Acoustic image normal position regenerative mode

摘要

PURPOSE:To improve both the attendant feeling and the directional feeling of sounds by controlling a sound image static for a frequency band from which the perception of an auditory direction can be obtained using plural speakers, reproducing the sounds from the plural speakers, executing no control for the sound image static for the other frequency bands, and reproducing the sounds using a single speaker. CONSTITUTION:Voices related to the second frequency band 22 and the third frequency band 23 to perceive the auditory directional feeling are reproduced using the plural speakers while sound image static control is executed. On the other hand, voices and environmental sounds related to the first frequency band 21 and the fourth frequency band 24 not to perceive the directional feeling are reproduced from the single speaker provided near a television set, etc. Consequently, since the plural speakers are never used when the voices of the first and fourth frequency bands 21 and 24 are to be reproduced, used, the blur of the sounds caused by plural sound sources never occurs, and the accuracy of the sound image static of the second and third frequency bands 22 and 23 to obtain the perception of the direction can be improved. Thus, both the attendant feeling and the directional feeling of the sounds can be improved in a communication conference.
