Objective To analyze the factors affecting the effects of hearing aids in presbycusis patients . Methods One hundred and twenty cases with presbycusis were investigated by using general data and the Satisfac-tion with Amplification in Daily Life questionnaire(SADL) .The individual scores and total scores of all the subjects were collected together with the personal information ,including age ,gender ,degree of education ,pure-tone aver-age ,hearing aid type ,monaural/binaural status ,total hearing aid experience ,daily use time ,the time of perceived hearing difficulty .A single factor analysis and multiple stepwise regression analysis were used to filter out main fac-tors influencing the effect of hearing aids .Results The degree of education ,hearing aid type ,monaural/binaural status ,daily use time ,the time of perceived hearing difficulty were factors influencing the effect of hearing aids . The patients with higher level of education ,the longer daily use ,binaural status obtained more scores than those of the low degree of education ,the shorter daily use ,and monaural status( P< 0 .01) .The older people felt better than the youngers(P<0 .01) .The patients with long -time perceived hearing difficulty got more scores than those with short -time perceived hearing difficulty (P<0 .01) .In general ,the degree of education ,and the daily use time were the main factors influencing the effects of hearing aids .Conclusion There are many factors that influence the effects of hearing aids ,in which the degree of education ,daily use time are the main factors ,and the combination of the two factors obtain the effects of hearing aid maximization ,and the binaural status ,the short time of perceived hearing difficulty and the older obtain better satisfaction .The gender doesn't significantly influence the effects of the hearing aids .
