Abstract

The aim of this study was to determine the basic properties of the 2f2-f1 distortion product otoacoustic emissions (DPOEs) in 36 normally hearing subjects and to compare their characteristics with those of the2f1-f2 DPOEs. The influence of stimulation parameters on 2f2-f1 DPOE behaviour was examined: i) stimulation levels varied from 40 to 70 dB sound pressure level in 10 dB steps; and ii) two values of the f2/f1 ratio were used (1.12 and 1.22). The prevalence and the level of the 2f2-f1 DPOEs depended on three parameters: f2 frequency, stimulation level and f2/f1 ratio. The results showed many differences between the characteristics of 2f1-f2 and 2f2-f1 DPOEs, probably due to their being generated by different mechanisms. Thus, the 2f2-f1 DPOEs may provide different information about the cochlear status and could be of clinical interest.
