What is the 1000 Hz tympanometry test and when should it be used?
When the baby is less than 6 months old, it is necessary to use a higher (1000 Hz) probe tone frequency to get an accurate tympanometry reading. This is because the walls of the baby’s ear canals are very soft and flexible at this young age and standard tympanometry test parameters using a lower (226 Hz) probe tone do not yield accurate results.
