Abstract

The ASHA (1988) SRT procedure (SRT 1) was compared with the Martin and Dowdy (1986) procedure (SRT 2) for equivalence between the two procedures, agreement between the pure-tone average (PTA) and SRT, and the time required to establish the SRT. Subjects included 30 adult listeners divided into two groups based on hearing status: Group 1 consisted of 15 adults with normal hearing sensitivity and Group 2 consisted of 15 adults with varying degrees of hearing loss. Results indicated that for clinical purposes, SRT 1 and SRT 2 were essentially equivalent. There was better agreement between SRT 2 and the PTA for both groups of subjects, although for Group 2 there was better agreement between the two-best frequency PTA and the SRT than the three-frequency PTA and the SRT. The time taken to obtain SRT 2 was significantly lower (by approximately one minute) than the time taken to obtain SRT 1. Overall, it was determined that the Martin and Dowdy (1986) SRT procedure is valid (as defined by similarity between SRT and PTA), easy to learn, and very efficient. It is highly recommended as a clinical procedure in audiometric testing of individuals with normal hearing and with various degrees of hearing impairments.
