Start pressure:
the pressure that is first introduced when
performing tympanometry.
Stop pressure:
the end pressure of the tympanometry
measurement (Figure 106).
NOTE:
MI 24 version, the start pressure must be a higher
value than the stop pressure. MI 34 version, the start
pressure can be higher or lower than the stop pressure.
This way,
Tympanometric
measurements can be
performed with decreasing or ascending pressure.
