It has been reported that healthy persons with normal hearing and without complain of tinnitus have perceivable tinnitus, when the ambient noise level is low. Such tinnitus was observed in 44 (72.1%) of 61 healthy adults with normal hearing in a sound-proof room. In most (91%) of them, tinnitus resembled pure tone, and was composed of middle or high pitch tone.
Since their frequency was conce n trated in some ranges relating to each other as multiples, it is suggested that some resonance mechanism in the body is involved in the generation of this type of tinnitus.
