Abstract
Three groups of postlingually deaf adults were selected, trained and followed for about 2 years. The subjects with residual hearing were fitted with a powerful hearing aid (HA group, N = 10), the rest were given a single channel vibrotactile aid (V group, N = 8) or received a single channel cochlear implant (Cl group, N = 10). The subjects were asked to evaluate the subjective benefit, disadvantage and magnitude of hearing impairment after the rehabilitation. Although the HA group achieved the highest scores in the audiological tests, the interviews revealed that the CI group found the implant quite beneficial in everyday life and in changing their attitude towards the handicap. After 2 years of use, this group reported the highest index of benefit, the best discrimination of everyday sounds and used the device most frequently. The V group were not as satisfied with their devices as the CI and HA groups.
