PURPOSE:To progress storing effect and to study efficiently by adjusting sound volume separating sound output signal to right and left, delaying the signal in manually or automatically for the right and the left independently and giving the signal time-differentially to wheels or right and left with two headphones. CONSTITUTION:The output of a microphone 10 is inputted from a terminal 11 and is distributed to two signals at a sound volume adjuster 12. By the output of a control circuit 15, separate delay times are generated on separated signals at delay circuits 13 and 14. With setting the delay time as between 0-10 seconds and also, permitting the inversion of a phase, time difference signals are given to right and left ears through right and left headphones 16. Thus, the storing effect is progressed and study is performed effectively, improving efficiency. |
