Training system and method for sound directional discrimination ability

A method for training a sound directional discrimination ability, which is performed by a system for training the sound directional discrimination ability, which includes a speaker, a microphone, a training sound reproduction unit, a response information determination unit, and a level control unit, the method comprising:

• (a) a step in which the speaker is disposed to be located within an angle range determined left and right in front of a human dummy, or disposed in front of a rotating subject and generates a sound directional training sound multiple times;
• (b) a step in which the microphone is worn on each of both ears of the human dummy or the subject, and acquires the multiple training sounds received from the speaker, in which the microphone acquires the training sound multiple times between the human dummy and the speaker or between one ear of the rotating subject and the speaker for each of multiple set angles;
• (c) a step in which the training sound reproduction unit reproduces at least some of the acquired training sounds for the each set angle with respect to the subject;
• (d) a step in which the response information determination unit provides the subject with multiple visual targets for the each set angle, and determines whether the subject selects a correct response visual target corresponding to the set angle of the reproduced training sound among the multiple visual targets;
• (e) a step in which the level control unit selects at least one angle among the set angles of the training sound to be reproduced to the subject;
• (f) a step in which the training sound reproduction unit reproduces at least one training sound according to the angle set by the level control unit to the subject;
• and
• (g) a step of repeating steps (d) to (f) above.
