1.4.2 Licenses
The touchTymp comes with some optional measurements which can be activated by
entering a license key. In the settings (see section 5.6.19) this key can be added.
The following functions are available:
• Tympanometry 1000 Hz (all versions)
• Acoustic Reflexes Contra (MI 26 version only, included in MI 36 version)
• Audiometry Bone Conduction incl. Masking (MI 26 version only, included in
MI 36 version)
• RaceCar (all versions)
• PC Connection (all versions, for connection with MAICO Sessions)
It might appear that the touchTymp already contains licenses due to the version you
ordered (e.g. if ordered touchTymp MI 26 version comes with a probe tone of 1000 Hz
for Tympanometry and Acoustic Reflexes).
NOTE: Each license key is specific for the serial number of your device.
In case you want to purchase another license, please, contact MAICO or your local
distributor to determine eligibility.
1.4.3 Printing Options
Printing test results from the touchTymp are accomplished in a variety of ways:
• Use the build-in printer to directly print results.
• Transfer touchTymp test data into the PC-software and print results on your PC-printer.
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)
• Bone Conduction incl. Masking (extra Licenses for MI 26, included in MI 36 version)
The functions are described in detail in the following sections.
1.5.2 Tympanometry
Tympanometry is the objective measurement of middle ear mobility (compliance
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
Compliance is measured with respect to an equivalent volume of air, with the scientific quantity milliliter (ml).
Air pressure is measured in deca-Pascals (daPa).
