Descriptive Characterization of High-Frequency Distortion Product Otoacoustic Emission Source Components in Children.

ABSTRACT:

Purpose

Distortion product otoacoustic emissions (DPOAEs) provide an objective assessment of cochlear function and are used for serial ototoxicity monitoring in pediatric cancer patients. DPOAEs are modeled as having distortion (near f₂) and reflection (near 2f₁-f₂) component sources, and developmental changes are observed in these components' relative strengths in infants compared with adults. However, little is known about source component strengths in childhood or at extended high frequencies (EHFs; > 8 kHz). Thus, the purpose of this study was to describe the effects of age and stimulus frequency on DPOAE components in children.

Method

DPOAEs were collected with varied frequency ratios (f₂/f
