    ¡¾Abstract¡¿ AIM: To study the characteristics of newborn hearing screening by transient evoked otoacoustic emission (TEOAE) echoª²screen model of Capella otoacoustic emission apparatus. METHODS: The 147 babies included in this study were all 1-3 d old, born with full months, with a weight of no less than 2.5 kg, with physiological reflects, without any abnormalities and their mother with no history of diseases or drug use during pregnancy. The babies first underwent distortion product otoacoustic emission (DPOAE) examination, then they were examined by Capella otoacoustic emission with the surrounding noise less than 40 dB SPL. RESULTS: Of the 147 cases, both ears were found "refer" in 5 babies, and they passed the examination of auditory brainstem response (ABR) and the measurement of acoustic immittance at 42 days. Left ears were found "refer" in 6 babies in the first screening and they passed one month later. The mean time used for the examination was (23.5¡À20.9) s and the rate of "pass" and "refer" between both ears or both genders was similar (P>0.05). CONCLUSION: TEOAE echoª²screen model of Capella otoacoustic emission apparatus is a simple, objective, timeª²saving examination, which can be performed with the surrounding noise under 40 dB SPL, and we it for newborn hearing screening. ......
