Objective: Survery and comparison between the physical characteristics of Distortion-Product Otoacoustic Emissions of 1-59 day-old normal-hearing newborns refered to TUMS, Rehabilitation School , Audiology department , 2002 Method & Material : This analytical-descriptive study was conducted on the ears of 102 easy method selected newborns. The tests included: otoscopy , BOA, Immittance audiometry , DPOAEs, and ABR if necessary. The amplitude and frequency of 2f1-f2 emissions of DPOAEs evoked by two pure tones (L1=65 dBSPL , L2=50 dBSPL and f2/f1=1.2) were also calculated. Results: 1-All normal hearing newborns have normal DPOAEs. No significant difference was observed in test-retest. 2- The amplitude of the DPOAEs to the right ear is significantly greater than the amplitude of the left ear (P<00.05). 3- No significant difference was observed between newborn&aposs DPOAEs in terms of their gender. Conclusion: DPOAEs could be measured quickly and noninvasively and are excellent tools for the screening of newborn hearing loss. The results are valid only within the Context of this research. |
