The results of survey of tinnitus in hearing impaired children of primary and junior high school pupils in Yokohama City are reported. The questionaires were obtained from teachers of 6 special classes for training of the hearing impaired pupils.
58 children with 75dB of the mean hearing level in the primary (6 to 12-year-old) and the jounior high (12 to 15-year-old) schools were inquired about tinnitus. In a sample of the children aged 6 to 8, tinnitus was found in only one patient because of the difficulty to make them understand about tinnitus. In the other sample, 11 patients with tinnitus (31%) were found. Among the 12 cases, only 2 cases had constant tinnitus and the remainder had intermittent tinnitus. Tinnitus were expressed as /pi:/ by 8 cases. Many children claimed the tinnitus was annoying.
