Pure-tone sensitivity and speech recognition measurements in quiet are vital components in audiologic evaluation. Pure-tone hearing threshold level increases in proportion to ages and affects speech recognition threshold (SRT). The purpose of this study was to find out the relationship between changes in pure-tone threshold averages (PTAs) and SRTs as a function of ages. Sixty adults (120 ears) with normal hearing, aged 20 to 69 years, were participated. SRTs were performed by IEC 60645-2, and used with Korean Standard bisyllabic word list for adults (KS-BWL-A). As a results, there were significantly correlated PTAs and SRTs. SRT, 0.49 dB/year, increased more fast compare to PTA, 0.34 dB/year. These finding suggested to be used as reference data for determining reliability of pure-tone audiometry for the elderly. KCI Citation Count: 4
