Abstract

Glenis Long and colleagues (Talmadge et al., JASA, 105, p. 275) were among the first to model and describe the characteristics of distortion-product otoacoustic emissions (DPOAEs) using two sub-components from different, cochlear sources. It is now accepted that there is a generator component that results from inter-modulation distortion created by nonlinearity in the outer hair cell near the f2 place. The reflection component predominantly arises from coherent reflection near the characteristic place corresponding to the frequency of the distortion product. Because the two components are generated through different mechanisms, it has been hypothesized that they may be differentially affected by human development. The goal of this presentation is to discuss ongoing research of DPOAE components in newborns, infants and adults. Analysis of the components indicates that the relationship between growth rates for generator and reflection components are significantly different between infants and adults. Furthermore, the phase functions for both components are different among groups. Possible sources for these differences will be discussed.
