Tinnitus in Normal Hearing Persons

Abstract

It has been well known that some of the patients complaining tinnitus has no hearing disorders. Based on our clinical studies we tried to get a clue of the cause of tinnitus in normal hearing persons. In this paper three possibil ities as the cause of it are proposed.
1) There may be some hearing disorders which can't be detected with usual pure tone audiometry.
2) In the soundproof room we feel a kind of tinnitus, which may be exaggerate with psychological factors in some patients.
3) Objective tinnitus can be one of causes of it.
