Abstract
The presence of hearing impairment deteriorates patients' quality of life by affecting their daily-life communication. Several self-report assessments are available to evaluate the subjective outcome of hearing aids, however, the procedures to evaluate the impairment of communication induced by hearing impairment has not been well established. A PC-recorded audio file prepared to evaluate the communication ability of hearing aid users, by extracting fifteen spoken language items from the Communication ADL Test: sp-CADL. A before and after study was performed among the hearing aid users who were attending Okayama University Hospital to evaluate the improvement in each of the 15 sp-CADL scores. Twenty-one adults were included in this study whose age ranged from 22 to 83 years old (mean: 56.7 years old). The total and individual scores of the sp-CADL improved significantly after the use of the hearing aids (p < 0.05). The total sp-CADL score of the patients with hearing aids showed a good correlation with the best scores of the speech discrimination test measured before wearing hearing aids.
