Abstract:
Objective To investigate the relationship between pure -tone audiometry (PTA ) ,speech dis‐crimination abilities in quiet or in noise and the international outcome inventory for hearing aids (IOI-HA) in pres‐bycusis patients .Methods Twenty presbycusis subjects were tested in this study .Pure-tone audiometry (PTA) and speech discrimination threshold were obtained before being fitted with hearing aids .They weared hearig aids more than six months ,and pure-tone audiometry ,speech discrimination scores in quite(the level = 65 dB SPL) and in noise(signal to noise ratio = 10 dB) were carried out in sound field .A stepwise forward multiple-regression analysis was performed to investigate the impact of PTA and speech discrimination scores to IOI-HA .Results The PTAs before or after hearing aid fittings showed a negative association with IOI-HA ,while speech discrimination scores in quiet or in noise before or after hearing aid fittings showed a positive association with IOI-HA .Speech discrimination threshold in noise was identified as a single predictor of IOI-HA(P<0 .001) .Conclusion The relation between speech discrimination scores in noise and IOI-HA suggests that a poor score might limit the hearing aids outcome .The speech discrimination scores in noise help the clinicians predict the outcomes of hearing aid in real‐ities .
