Abstract
In a stereophonic sound reproduction system in which stereophonic left and right signals are treated to have a level difference therebetween for establishing a localized sound image spaced from the midpoint between left and right loudspeakers, the level difference between such left and right signals is reduced as the frequency thereof increases for improving the localization of the sound image resulting from the application of the resulting or converted left and right signals to the left and right loudspeakers.
Claims9
In a stereophonic sound reproduction system having a pair of spaced apart left and right loudspeakers and providing stereophonic left and right signals with a level difference therebetween for producing a sound image localized at a position spaced from the midpoint between said loudspeakers when said stereophonic left and right signals are respectively applied to said left and right loudspeakers;
- a converting circuit comprising left and right input terminals respectively receiving said stereophonic left and right signals, left and right output terminals connected with said left and right loudspeakers, respectively, means for transmitting said left and right signals from said left and right input terminals to said left and right output terminals, respectively, and frequency responsive means for reducing the level difference between said left and right signals, as transmitted to said left and right output terminals, in response to increases in the frequency of said signals so as to improve the localization of the resulting sound image.
