高度難聴児3症例の聴性定常反応について - A S S R の長所とその問題点-

We report three representative infants with severe sensori-neural hearing loss who underwent auditory steady-state response (ASSR) and conditioned orientation reflex audiometry (COR). The differences in thresholds between ASSR and COR were only 5 to 15 dB. The results of our experiments showed that ASSR was useful for cases with high frequency hearing loss and differences in thresholds between the right and left ears. Though ASSR is a time-consuming procedure, its frequencyspecific hearing assessment is useful for determining the hearing aid volume and confirming whether or not a cochlear implantation should be performed.
