<p>PURPOSE:To achieve handy and accurate training of audibility in an audibility training system adapted to make the audible sense correspond to a physical property. CONSTITUTION:A sound source for training inputted by an audio signal input means 1 is recorded by a recording means 3. But, several seconds before the recording of the sound source, a control signal is inputted by a control signal input means 2 to update a program number of the recording means 3. The control signal recorded by the recording means 3 is decoded into the program number by a control signal judging means 5 and one solution corresponding to the program number is selected from among solution memory 4 by a solution selection means 6. On the other hand, the sound source for training recorded in the recording means 3 is amplified with an amplifier 9 and reproduced with a speaker 10. The solution selected by a solution selection means 5 is displayed by a response display means 8 after time adjustment is performed by a solution output time control means 7 so that the sound source is outputted several sec. after the reproduction of the sound source.</p> |
