Effect of the degree of sensorineural hearing impairment on the results of subjective evaluations of a noise-reduction algorithm

摘要: Performed subjective evaluations using subjects with various hearing impairments.Compared the perceptual effects of three noise-reduction algorithms.No significant differences in preference and intelligibility improvement.Significant quality improvement. Subjective a specific (NR) algorithm for hearing-support devices have frequently been performed normal-hearing (NH) participants because financial, time, ethical constraints. However, same NR evaluation may differ accordance degree ability subjects. In this study, we 45 different degrees sensorineural impairment to assess whether certain aspects preference, quality, are affected by ability. We recruited 15 NH subjects, hearing-impaired (SNHI) moderate loss, SNHI moderately-severe intelligibility, tests algorithms. Experimental results demonstrated that were not significantly regards improvement speech but quality.
