Classification of trace patterns of 226- and 1000-Hz tympanometry in healthy neonates

In healthy neonates without risk factors for hearing loss, 1000 Hz tympanograms can be recorded and interpreted. A single-peaked tympanograms was most common in ears with normal TEOAE. In ears with abnormal TEOAE, tympanograms were classified as abnormal more frequently using 1000 Hz than 226 Hz. Implementation of tympanometry using 1000 Hz probe tone in newborn hearing screening programs may provide valuable information regarding middle ear dysfunction that may cause transient conductive hearing loss.
