Abstract: Objective To investigate the auditory condition in adults with hearing-impairment and evaluate the outcome of the hearing aid. Methods The threshold of air-bone-conduction audiometry and binaural hearing aid in 91 adults were determined with pure tone audiometry,and their satisfaction to hearing aids were investigated with free interview. Results The threshold of hearing and hearing aid were positively correlated. The satisfaction did not significantly correlate with the threshold of hearing aid, but with the time of deprivation of hearing. The hearing threshold classification was better in the patients with the audiogram of flat, raising, slow down type than with audiogram of Shu type, which defined as hearing reacted only in 1 or 2 frequency. Conclusion It is important to improve the primary otology protection, as well as the rehabilitation from the hearing aids.
