Tympanometry
is the objective measurement of middle ear mobility (compliance

)
and pressure
2
within the middle ear system (Figure 1). During the test, a low-pitched
probe tone (226 Hz) is presented to the ear canal by means of the hand-held probe.
This tone is used to measure the change in compliance in the middle ear system while
1
Compliance is measured with respect to an equivalent volume of air, with the scientific quantity milliliter (ml).
2
Air pressure is measured in deca-Pascals (daPa).
