8 How to test children
When practicing impedance measurement with small children, be aware of problems
caused by the child being restless or afraid of the examination or reacting sensitively
to the change of pressure and the loud test sound. There are also different
conditions of the eardrum and the middle ear which do not appear in ears of adults.
It may be difficult to create a probe seal with restless children. If the child yawns or
cries, the instrument will not have stable pressure in the outer auditory canal. In
addition, speaking causes Stapedius muscle reflexes which lead to a change in the
compliance of the eardrum.
The child should be made familiar with the surroundings and the ear being touched
by the probe in order to carry out a successful impedance measurement. This could
be done by getting in touch with the child and by playfully touching the ear with the
probe. If you can touch the ear without problems, the child will normally accept the
probe being inserted.
