Usefulness of 1000-Hz probe tone in tympanometry according to age in Korean infants

摘要

Objective: Numerous studies have shown the superiority of a 1000-Hz frequency probe tone for evaluating the middle ear status of infants. However, most of these studies examined Caucasian populations. This study validated the 1000-Hz probe tone and evaluated the age at which it should be used in Korean infants.
