Abstract
The differences between hearing aids with and without noise reduction in relation to the purchasing ratio, frequency response and compression ratio of hearing aids were examined in 148 patients with hearing loss. The patients ranged in age from 20 to 89 years old. The results were as follows.<br>1) Patients in their fifties showed the highest purchase ratio of hearing aids with noise reduction.<br>2) In relation to the frequency response, the output sound pressure level at low frequency ranges below 2000Hz was higher in the hearing aids with noise reduction than in those without noise reduction.<br>3) The compression ratio of hearing aids at high frequency ranges above 1000Hz were higher in the hearing aids with noise reduction than in those without noise reduction.<br>These results may be useful for hearing-aid-fitting of digital hearing aids with noise reduction.
