- Abstract
We examined 114 patients aged 10 to 91 years with different kinds of hearing aids fitted in one ear only, the unaided ear acting as a control. They were re-examined several times during a period of follow-up from 1 to 9 years comparing the relative change in hearing due to hearing aid usage with various degrees of amplification of the aid. We compared the degree of hearing loss in the aided and unaided ear looking for evidence of a possible change in hearing related to the frequency of hearing aid usage in hours per day and in years, the maximum power output (MPO) and the gain of the aid. According to our findings there is no change in hearing between the aided and the unaided ear at the alpha = 0.05 probability level at least for 8 years. There is no effect of the long-term amplification of the hearing aid on deterioration of hearing comparing the aided ear and the unaided ear, but with high MPO of the aid, the patient should be followed up more frequently than with low MPO amplification.
