Correlation between the handicap and the benefit of hearing aid use in adults and elderly. Rev. soc. bras. fonoaudiol. [online]. 2011, vol.16, n.2, pp. 160-166.

PURPOSE: To study the benefit obtained by the use of hearing aids in environments acoustically favorable to communication, reverberant, noisy and with aversive sounds, and to correlate the benefit with the handicap of adults and elderly with hearing loss. METHODS: Participants were 42 individuals attended at the institution where the study was carried. They answered the questionnaires Hearing Handicap Inventory for Elderly or for Adults, and Abbreviated Profile of Hearing Aid Benefit both when they received the hearing aids and after three months of its effective use. The participation constraints, hearing difficulties and the benefit brought by the use of hearing aids were studied. The results were statistically analyzed. RESULTS: There were differences between the scores from the questionnaires Hearing Handicap Inventory for Elderly and Hearing Handicap Inventory for Adults and the subscales Ease of Communication, Reverberation and Background Noise from the Abbreviated Profile of Hearing Aid Benefit, comparing the conditions with and without hearing aids. There was a positive correlation between the benefit measured by the subscale Ease of Communication, for the elderly subjects, and Background Noise, for the adult subjects, with decrease of the participation constraint. CONCLUSION: Adult and elderly subjects showed a reduction of handicap in daily activities with the use of hearing aids. The bigger the benefit obtained in the subscale Ease of Communication for the elderly and in the subscale Background Noise for the adults, the greater the handicap reduction.
