Aim. To study the effectiveness of phoneme perception test for evaluation of different hearing aids’ types performance
Methods. Hearing aid was provided to 100 patients aged 45-59 years with bilateral chronic sensorineural moderate and moderate-to-severe hearing loss. 4 equal groups were formed depending on the type of a hearing aid - behind-the-ear with standard (BTE) and slim (BTEslim) tubes, receiver-in-the-canal (RIC), and completely-in-the-canal (CIC). All devices had comparable characteristics and were fitted monaurally. The efficacy was evaluated by phoneme perceprion test, which was performed before and 12 weeks after the correction (with and without the hearing aid).
Results. The detection test before correction revealed 38 deviations from the expected numbers, after 3-month adaptation - 28 without the device and 23 with it reflecting the significant dynamics compared to baseline parameters in CIC group (p
