Otoacoustic emissions in newborns evoked by 0.5Â kHz tone bursts

Use of 0.5 kHz TBOAEs may be a useful addition to standard CEOAE tests in newborns. They provide information about lower frequencies, a region where CEOAEs are usually prone to noise. The presence of SOAEs affects the magnitudes of both CEOAEs and TBOAEs.
