Summary

The paper describes the analysis of quantitative contribution of binaural amplification in contrast to monaural one in persons with primary application of hearing aid on both ears as compared with persons after long-term adaptation to monaural amplification, specifically in precisely defined signal-to-noise ratios (SNR). Consequently, 83 persons (right-handed) adapted for at least 5 years to monaural use of the hearing aid on the right ear and 106 first-users of binaural amplification, who have had no experience with the hearing aid before, have been examined. The results indicate that the contribution of the hearing aid on the other ear in symmetrical hearing loss was statistically comparable in both groups.

Key words:
monaural, amplification, acoustic information, frequency analysis, digital hearing aid.
