1.5 Description
1.5.1 General
The touchTymp is designed for Immittance testing as Tympanometry and Acoustic
Reflex (i.e. Ipsilateral and Contralateral) testing (MI 26 and MI 36 version).
MI 36 version also includes Reflex Decay and Eustachian Tube Function (ETF) tests.
MI 26 and MI 36 also include Audiometry functions:
•Air Conduction (all versions)
•BoneConduction incl.Masking(extraLicensesforMI26,includedinMI36version)
The functions are described in detail in the following sections.
1.5.2 Tympanometry
Tympanometry is the objective measurement of middle ear mobility (compliance
1
)
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).

Operation Manual touchTymp MI 26 and MI 36 Version
8511780 Rev. 4
7
30/06/2021
the air pressure is varied automatically from a positive value (i.e. +200 daPa) to a
negative value (i.e. -400 daPa max).
Figure 1
Maximum compliance of the middle ear system occurs, when the pressure in the
middle ear cavity is equal to the pressure in the external auditory canal. This is the
highest peak of the curve as it is recorded on the chart. The position of the peak on the
horizontal axis and on the vertical axis of the chart will provide diagnostic information
regarding the function of the middle ear system. Gradient calculations are reported as
the Tympanogram width at half of peak compliance expressed in daPa. A normative
box is available on both the display and printout to aid in diagnosis.
NOTE: 1 mmho ≙1 ml for 226 Hz probe tone
1.5.3 Acoustic Reflex
An Acoustic Reflex, or contraction of the stapedial muscle, occurs under normal
conditions when a sufficiently intense sound is presented to the auditory pathway. This
contraction of the muscle causes a stiffening of the ossicular chain which changes the
compliance of the middle ear system. As in Tympanometry, a probe tone is used to
measure this change in compliance.
When the stimulus presentation and measurement are made in the same ear by means
of the probe, this acoustical reflex is referred to as an Ipsilateral Acoustic Reflex.
When the stimulus presentation ismade in the opposite ear ofwhere themeasurement
is made, this acoustical reflex is referred to as a Contralateral Acoustic Reflex.
For best results, this reflex measurement is automatically conducted at the air pressure
value where the compliance peak occurred during the Tympanometric test. Stimulus
tones of varying intensities at 500 Hz, 1000 Hz, 2000 Hz or 4000 Hz are presented as
short bursts. If a change in compliance greater than the selected value is detected, a
reflex is considered present. Because this is an extremely small compliance change,
any movement of the probe during the test may produce an artifact (false response).
The test result is recorded as Pass/No Response (NR), and in graphical form.
If the Tympanometric results display any abnormal findings, the results of the
Acoustic Reflex testing may be inconclusive and should be interpreted with care.
Theoretically, a compliance peak is necessary to observe a reflex at peak pressure.

1.5.4 Acoustic Reflex Decay (MI 36 Version Only)
Acoustic reflex decay, also known as adaptation, is the measurement of the acoustic
reflex response during sustained stimulus presentation. Ipsilateral and Contralateral
Reflex Decay can be performed.
1.5.5 Eustachian Tube Dysfunction (ETF) (MI 36 Version Only)
The Eustachian tube connects the middle ear with the nasopharynx. Its function is to
equalize pressure between the middle ear and the atmosphere.
The Eustachian tube test canbe used to determine ifthe Eustachian tube is functioning
properly in patients.
•ETF Intact: performed on patients with normal tympanic membrane (TM).
•ETF Perforated: determines if the patient can open his/her Eustachian tube when
the TM is perforated or an open PE-tube is in place.
1.5.6 Air Conduction Testing
Hearing threshold levels can be determined by presenting test signals to the test
subject with the included headphones (Air Conduction –AC). The purpose of AC
audiometry is to establish the hearing sensitivity at various frequencies. The test can
specify the AC loss but cannot distinguish between a conductive versus a
sensorineural abnormality.
1.5.7BoneConduction Testing(MI26Version–ExtraLicense,MI36Version–Included)
Hearing threshold levels can be determined by presenting test signals to the test
subject with the included bone conductor (Bone Conduction –BC). The purpose of
BC audiometry is to establish the hearing sensitivity at various frequencies. The test
can specify the BC loss in combination with AC loss it can distinguish between
conductive versus a sensorineural abnormality.
1.5.8Masking(MI26Version–ExtraBoneConductionLicense,MI36Version–Included)
Masking is required if there is a notable threshold difference between the left and right
ears. It is possible for sound to be transmitted to both ears via bone conduction while
testing the poorer ear. This is called “crossover”.
Crossover occurs often while testing bone conduction, but it can also occur during air
conduction testing. Relevant to crossover is the sound level received by the opposite
ear. The difference between the original test signal in the test ear and the received
signal in the opposite ear is called “interaural attenuation”.
For Bone Conduction measurements the interaural attenuation is 0 dB to 15 dB.
Bone Conduction crossover is therefore possible even with a slight difference in
hearing loss between ears.

Figure 14
Operating the touchTymp will require the use of eartips –
either mushroom shaped (1) or umbrella (2) eartips
(Figure 14).
Eartips are intended for single-use only. These should be
discarded after use. They cannot be cleaned.
In case of re-use of the single-use equipment you
enhance the risk of cross contamination!
MAICO strongly recommends to use Sanibel eartips only. In case you want to purchase
further disposables, please contact MAICO or your local distributor.
3.5 Components/Replacement Parts
Some reusable components are subject to wear with use over time. MAICO
recommends that you keep theses replacement parts available (as appropriate for your
