Fifty-eight children (from 4 to 19 years of age) with bilateral, symmetrical, sensorineural hearing loss, who had used a hearing aid in only one ear for 1 to 19 years were investigated to study the influence of hearing-aid upon the residual hearing between the used and no used ears.<br>The results were as follows, <br>1)The average hearing level for the used ear at seven frequencies was 49. 5dB of prehearingaid usage and was 53.8dB of posthearing-aid usage. The discrepancy of audiograms between the aided and unaided ear was not remarkable.<br>2)The hearings for both the aided and the unaided ears in Audiograms was progressive for a long time. But no significance relation was observed between changes in used-ear hearing of the aided and unaided ears.<br>3)When the hearing levels of the children were scrutinised on an individual basis, it was found that 9 cases (15. 5%) in both ears, 2 cases (3. 4%) in only used ear and 1 case (1. 7%) in only no used ear out of 58 cases showed deterioration of hearing.<br>4)These data did not lead us to the conclusion that hearing-aid usage was detrimental on the residual hearing of children with sensorineural hearing loss.
