  • Title: Detection improvement for neonatal click evoked otoacoustic emissions by time-frequency filtering.
    Author: Zhang VW, Zhang ZG, McPherson B, Hu Y, Hung YS.
    Journal: Comput Biol Med; 2011 Aug; 41(8):675-86. PubMed ID: 21703604.
    Abstract:
    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.
