Efficacies of the hearing aids with different frequency responses were studied in 16 cases of moderate or moderately-severe sensorineural hearing loss.
Cases with similar audiograms were divided into two groups based on their severity of speech intelligibility. Speech discrimination tests using hearing aids of various frequency responses revealed that low frequency amplification of the aids improved the discrimination scores in a group with good speech intelligibility. In the group with poor intelligibility, low frequency amplification did not affect their discrimination scores.
For better selection of a hearing aid, the type of audiogram as well as speech intelligibility should be taken into account.
