Abstract
Objective To investigate the application of auditory steady state responses (ASSR) in the infants hearing screening. Methods ASSR was tested in 32 cases (64 ears) of infants with no reaction to otoacoustic emission (OAE) in our hospital between December 2007 and December 2008. Results No V wave was educed in the 32 infants (64 ears) with OAE, but the positive educing rates of ASSR were respectively 3.13%(2/64), 6.26%(4/64), 7.81%(5/64), 9.39%(6/64) to the frequencies of 0.5, 1, 2 and 4 kHz (P<0.05). The corresponding thresholds with ASSR were (80.26±6.68) , (85.68±5.45) , (84.32± 4.32) and (86.56±4.26) dB HL, as compared to (26.58±4.52) dB HL with OAE (P<0.05). Conclnsion ASSR is helpful to decrease the false positive rate in the infants hearing screening, and therefore appears to be worthwhile for widespread use.
