Abstract: A training system for sound directional discrimination ability includes: a speaker that is located in an angle range determined left or right in front of a human dummy or disposed in front of a subject and generates a sound directional training sound multiple times; a microphone which is worn on each of both ears of a human dummy or the subject and obtains the training sound; a training sound reproduction unit for reproducing at least a part of the obtained training sound for each of the configuration angles; a response information determination unit for providing the subject with multiple visual targets for each of the configuration angles and determining whether the subject has selected a correct response visual target among the multiple visual targets; and a level control unit for selecting at least one angle among the configuration angles.
