Abstract:
Objective To investigate the speech recognition in noise in patients with unilateral conductive or mixed hearing impaired using Sophonotron Alpha 2 softband.Methods A total of 12 patients (12 ears) with unilateral conductive or mixed hearing loss participated in the survey and fitted with Sophonotron Alpha 2.The aided hearing threshold test and speech recognition test in noise were evaluated in both unaided and aided conditions.Results The average aided hearing threshold using Sophonotron Alpha 2 softband was 35.0±10.8 dB HL,showing significant improvement compared to that of unaided(P＜0.05).The average signal-to noise ratio loss was 5.9± 6.1 dB using Sophonotron Alpha 2 softband in noise,showing a more significant benefit than that of the unaided (13.6±10.9 dB).Conclusion The Sophonotron Alpha 2 softband can significantly improve speech recognition in noise for the patients with unilateral conductive or mixed hearing loss.
