| 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 twenty‐seven of 880 (48.5%) pairs of measurements did not differ by any more than 5 dB. With LPTATs as reference criterion, for a favourable four‐frequency average over 1.0, 2.0, 4.0 and 6.0 kHz with a cutoff of 20 dB HL, the sensitivity of the EDPTs was 92% and the specificity 62%; a cutoff of 30 dB HL increased the respective values to 98% and 77%. Conclusions: DPOAEgfs are acceptable for estimating hearing thresholds in individuals with intellectual disability who may have limitations in performing conventional audiometry.
