Can resonance frequency of the outer ear be measured in neonates using wideband tympanometry?

What is it about?

This study investigated the feasibility of measuring the resonance frequency (RF) in healthy neonates’ ears using wideband tympanometry (WBT). WBT measures admittance and absorbance as a function of frequency and ear canal pressure. Clinically, RF is the frequency at which the susceptance, the vertical component of admittance, equals zero. In this study, RF was successfully measured in 154 ears (114 newborns) out of 297 ears (182 newborns), which passed a battery of tests including automated auditory brainstem response,
