4 How to create a tympanogram
In the following paragraph we will briefly explain the principle and the background of
the impedance measurement to create a better understanding. If you want to begin
the measurements immediately, just skip this paragraph and continue reading section
4.3 “Preparing the Measurements.”
4.1 The basics of the impedance measurement
The impedance measurement assists
in diagnosing of the condition of the
middle ear and can therefore not be
compared directly with other
audiometric tests such as sound or
speech audiometry which assists in
the measurement of hearing.
Furthermore the impedance
measurement is an objective
measuring method which does not
depend on the cooperation of the
test person and can therefore not be
falsified by the patient.
The two most important impedance
measuring methods possible with
your MI 24 are tympanometry and
the measurement of the Stapedius
reflex which is discussed in chapter 5:
“How to measure the Stapedius
reflex.”
