This study employed a time-frequency filtering technique to improve click evoked otoacoustic emission (CEOAE) detection at lower frequency bands, and hence to reduce the number of referral cases in neonatal OAE screening. Using this approach the detectability of CEOAEs, in terms of lower frequency SNRs and whole wave reproducibility, was significantly improved. Evaluations of screening outcomes demonstrated this method significantly reduced the overall referral rate, by 2.5 percentage points in initial CEOAE hearing screening. This approach may have potential application in OAE technology and in neonatal hearing screening programmes.
本研究采用时频滤波技术来改善低频段的 click 诱发耳声发射（CEOAE）检测，从而减少新生儿 OAE 筛查中的转诊病例。使用这种方法，CEOAE 的可检测性在低频 SNR 和全波可重复性方面得到了显著提高。对筛查结果的评估表明，这种方法显著降低了总体转诊率，在初始 CEOAE 听力筛查中降低了 2.5 个百分点。这种方法可能在耳声发射技术和新生儿听力筛查计划中具有潜在的应用。
