Hearing Threshold Estimation With Distortion Product Otoacoustic Emission Growth Functions in People With Intellectual Disabilities in an Outreach Setting.

ABSTRACT:

Background

People with intellectual disabilities often have undetected hearing loss.

Methods

In this prospective observational study featuring 110 adults with intellectual disabilities, hearing evaluations based on objective hearing threshold estimation using distortion-product otoacoustic emission growth functions (DPOAEgfs) were performed in a sheltered workshop. Results were compared with thresholds obtained by conventional subjective pure-tone audiometry (cPTA) and the adaptive self-test PTA Multiple-Choice-Auditory-Graphical-Interactive-Check (MAGIC).

Results

The differences between the lowest thresholds obtained by cPTA and MAGIC for the frequencies 1, 2, 4 and 6 kHz (LPTATs) and the estimated distortion-product thresholds (EDPTs) were calculated. Four hundred t
