Survey on sound environment and hyperacusis for developmental disorders

Abstract

Hyperacusis, that is, unusual intolerance to ordinary environmental sounds, poses a health risk to a certain number of ordinary people. In particular, developmental disorders tend to have hyperacusis, but their difficulties in daily life are not socially recognized. In this paper, a questionnaire survey on hyperacusis for developmental disorders is carried out, and the actual conditions, what kinds of sound and situation cause the symptom, are figured out.
