摘要
目的探讨瞬态诱发耳声发射(TEOAE)的性别差异在新生儿与成人之间的变化。方法以短声刺激分别对120名(女62,男58)通过听力筛查的新生儿及53名(男26,女27)纯音听阈正常的青年成人行TEOAE检测,对两组TEOAE强度及频带信噪比(SNR)的性别差异进行分析。结果①成人组TEOAE强度性别差异(2.41dB)明显高于新生儿(0.99dB)。②新生儿SNR除1kHz男婴高于女婴外,其余频带均为女婴高于男婴,且SNR的性别差异随频率增加而增大,在3、4kHz差异有统计学意义(P<0.05)。成人不同频带SNR均为女性高于男性,除3kHz外也呈现随频率增加而增大的特征,在2、4kHz差异有统计学意义(P<0.05)。结论 TEOAE总强度的性别差异随年龄增加而增大,且新生儿及成人频带SNR的性别差异均随频率增加而增大,成人低频区SNR的性别差异较新生儿更明显。
