OBJECTIVE: The aim of this study was to investigate otoacoustic emissions in children with autism compared with their typically developing peers. MATERIALS and METHODS: Thirty-one children with autism (Mean age ± SD: 3,2 ± 0,8 years) and 17 typically developing control participants were examined (Mean age±SD: 3,5 ± 0,9 years). All participants had normal hearing (thresholds < 15 dB HL) and normal middle ear function. Since behavioral audiometry could not administered to many of the children with autism, auditory brainstem response (ABR) was used to detect hearing status, and Transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emissions (DPOAE) were measured in two groups. RESULTS: No significant difference in TEOAE test results was found between the children in two groups. But S/N of high frequency DPOAE's was greater in children with autism compared to the control group (p<0.05). CONCLUSION: Increased DPOAEs in high frequencies may be related to sound hypersensitivity that is reported in children with autism.

    Background: Wideband acoustic immittance measurements of the middle ear, such as wideband energy reflectance (ER), can provide information about how the middle ear functions across the traditional audiometric frequency range. These measurements are being investigated as a new means of evaluating...
