Feasibility of 1000 Hz tympanometry in infants: Tympanometric trace classification and choice of probe tone in relation to age

Abstract Objectives Universal newborn hearing screening (UNHS) has significantly reduced the age of children undergoing audiological examinations. Middle ear function is usually evaluated with tympanometry using a probe tone of 226 Hz, although higher frequencies are recommended in infants. The aim...

Zusammenfassung:Abstract Objectives Universal newborn hearing screening (UNHS) has significantly reduced the age of children undergoing audiological examinations. Middle ear function is usually evaluated with tympanometry using a probe tone of 226 Hz, although higher frequencies are recommended in infants. The aim of this study was to compare the feasibility of 226 and 1000 Hz tympanometry for different trace classification systems in relation to age, risk factors for hearing loss and ear canal volume. Methods Data from 577 infants (915 ears)
