 title = {Acoustic input impedance of infants with normal and pathological middle ear},
 abstract = {Newborns and infants often suffer from pathological conditions of the middle ear. In many cases, those conditions comprise liquid in the middle ear, e.g. middle ear effusion, or amniotic fluid during the very first days of life. In order to check the middle ear status in a fast and simple manner, the measurement of the infant’s ear acoustic input impedance could be a useful method. In an ongoing study, the acoustic input impedance of infants’ ears (aged from 2 weeks up to 5 months) was measured in the frequency range from 100 Hz to 10 kHz at ambient pressure. In addition, the middle ear status was assessed by ENT-specialists, yielding an expert classification of “normal” and “pathological” middle ears. The results, on the one hand, show a great variability at low and very high frequencies, reflecting the susceptibility of the measurements to movements and noise of the subjects. On the other hand, there is a frequency range in which a clear discrimination between normal and pathological middle ears seems to be possible. This discrimination appears to profit from the consideration of both the magnitude and phase information of the measured acoustic impedance, indicating that power-based methods may miss important information.},
