This was a prospective study using double-blind, within-subjects, repeated-measures, controlled trials evaluating the effectiveness of an automated customized enhanced technology based on the hearing profile captured on the mobile device. One hundred adults (60 with age-adjusted normal hearing and 40 with hearing loss) participated in this study. The performance of the subjects with customized and standard settings was compared using both subjective and objective measures. Speech recognition was measured in quiet and in noise using Cantonese disyllabic words. Subjective ratings on the quality, clarity and comfortableness of the mobile signals were measured with an 11-point visual analogue scale.
