Auditory training manner and sound treatment manner for auditory training and sound central processing unit for auditory training and record media null for auditory training
PROBLEM TO BE SOLVED: To enhance the effect of language learning by allowing a trainee to listen to the region attenuation processed sounds formed by attenuating a prescribed frequency range with respect to the original sounds. ;SOLUTION: The original sounds inputted from a sound source 10 are subjected to region attenuation processing at prescribed timing and patterns in accordance with band selection control signals by each of left and right channels in a band attenuation processing means 20 and are made into region attenuation processed signals which are outputted to the one input end of a switching means 30. Further, the original sounds inputted from the sound source 10 are inputted to the other input end of the switching means 30. The switching means 30 selects any of the input signals in accordance with the region attenuation processing patterns and outputs the same to a pan pot processing means 40. A phase inversion processing means 50 subjects the signals from the pan pot processing means 40 to phase inversion processing at the prescribed timing in accordance with phase inversion processing signals and outputs the signals to a voice amplifier means 60. The voice signals are converted to acoustic signals by a voice output mean 70 and are outputted as voices.;COPYRIGHT: (C)1999,JPO
