Objective: Adolescents may be at risk of noise-induced hearing loss due to recreational sound. The aim of this study was to examine the role of distortion product otoacoustic emissions (DPOAEs) in screening for early stages of high-frequency loss such as can be observed in noise-induced hearing loss. Setting and design: This cross-sectional study was embedded within Generation R, an ongoing prospective birth cohort study in Rotterdam, The Netherlands. Data were collected from April 2016 to September 2019. Methods: A total of 3456 adolescents with a mean age of 13 years and 8 months old (standard deviation ± 5 months) were included. Pure-tone thresholds were measured in a sound-treated booth. DPOAEs were recorded using an ILO V6 analyzer with primary levels of 65/55 dB SPL and frequency ratio f2/f1 of 1.22. Subjects had normal middle ear function at the time of assessment, based on tympanometry results. Results: Measurements in 6065 ears showed that DPOAE levels tend to decrease with increasing pure-tone thresholds. However, the intersubject variability of DPOAE levels in ears with the same threshold was large. DPOAE levels could reasonably identify early stages of high-frequency hearing loss. Conclusion: The findings of present study indicate that DPOAE measurements can potentially be used for adolescents hearing screening in the high frequencies. Future research is needed to optimize test performance.
