Background and Objective : This Investigation evaluated the level of subjective satisfaction in hearing aid
users by using Abbrieviate Profile of Hearing Aid Benefit (APHAB).
Materials and Methods : The APHAB is a subjective evaluation method for hearing aid users. The APHAB consists of 24 items with 4 subscales including Ease of Communication (EC), Reverberation (RV), Background noise (BN), and Aversiveness (AV). We applied for APHAB to evaluate the subjective satisfaction level in 45 compressive
types of hearing aids. The APHAB scores were evaluated according to the types of hearing loss,
audiologic patterns of pure tone audiograms, the degree of SRT and the types of hearing aids. In each
item, subjects respond to each question on the basis of how they believe the performance of their hearing
aid is using a 7-point scale. Subjects were tested both unaided and aided for each specified listening
situation. The hearing aid ’benefit’ is defined as the difference of percentage between the unaided and
aided performance scores.
Results : In SRT, moderate hearing loss group showed a higher satisfaction in
Ease of Communication, Aversiveness (p<0,05). The group that showed a flat audiogram revealed a higher
satisfaction in Ease of Communication, Background noise (p<0.01). There was no significant difference of
scores of benefit in types of hearing loss and types of hearing aids.
Conclusion : Hearing aids are more beneficial in patients who have moderate hearing loss and flat audiogram pattern.
