PERCEPTION SENSITIVITY EVALUATION DEVICE, AND OPERATION METHOD AND PROGRAM OF PERCEPTION SENSITIVITY EVALUATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an interference effect measuring technology based on an index different from prior art, and an audiometric technique using the interference effect.;SOLUTION: A perception sensitivity evaluation device 1 includes an input information acquisition part 14 that, when a sound stimulus that changes with time and a light stimulus that changes with time are presented to a subject, acquires the time sequence of motion information on the subject responding in accordance with the change in the light stimulus while the subject is listening to the presented sound stimulus, and an interference effect measuring part 15 that, when a difference between the time sequence of the change in the sound stimulus and the time sequence of the change in the light stimulus is called a stimulus difference, measures an interference effect based on a difference between the time sequence of the change in the light stimulus and the time sequence of the motion information in a predetermined stimulus difference, and if the interference effect is generated, determines that the sound stimulus is perceived.;SELECTED DRAWING: Figure 9;COPYRIGHT: (C)2016,JPO&INPIT
