A unique and powerful diagnostic combo

The AA222 combines the power of a clinical middle ear analyzer with a complete diagnostic audiometer.

Testing flexibility

AA222 is the perfect combination of audiometry and tympanometry in one powerful device. AA222 offers all the diagnostic middle ear analyzer and audiometry tests needed in the clinic. This makes the AA222 the obvious choice for the new clinic, the clinic with limited desk space, and for the mobile clinic.

Child distraction

To help distract children while obtaining the tympanogram and reflex measures, the AA222 can present a train moving across the lower part of the screen.

Extended licenses

The optional AA222 h-license additionally offers high frequency probe tones (678, 800 and 1000Hz) to optimize the testing of infants, manual tympanometry, reflex latency, Eustachian tube function test for patulous tympanic membrane (continuous sensitive impedance measurement) and binaural speech testing.

The AA222 also offers an optional QuickSIN test; a speech in noise test that provides a quick estimate of the signal-to-noise ratio.

Customizable protocols

The AA222 has the option to create user-defined impedance test protocols by combining different tests from the test battery into one test flow. For instance, you can create a simple screening procedure and a more in-depth evaluation. Avoid wasting time with different client types, as each test protocol can have separate test limits tailored to the needs of a specific patient group. Setting up user defined audiometry protocols provide easy access to the preference of each clinician in a clinic with multiple users.

Dedicated probe systems

The AA222 includes either a diagnostic probe or a clinical probe system depending on your needs.
The diagnostic probe is hand-held and ideal for quick tympanograms and a screening reflex.
The clinical probe is ideal for more lengthy assessments where stability is important and any interference from extraneous noise should be avoided.
You can choose to have both probe systems included with your AA222. It is quick and easy to change between the two probe systems. The clinical probe shoulder box can be placed on the client by using the optional headband, clips or key hanger.

The probe status

Probe status is displayed on the probe shoulder box for both probe systems which enables you to keep your focus on the client. Both probe types require only a simple button press to alternate between ears remotely.
Right ear/Probe is out of the ear.
Left ear/Probe is out of the ear.
Probe in ear/Seal is maintained
Probe in ear/Blocked or leaking
Probe status is unknown

Great overview of test results

The 10” adjustable display provides a great overview of the measurements where several test results can be seen on the same screen. The image is sharp and clear. The screen can be tipped and adjusted to avoid light reflection and provide the optimum ergonomics.
The built-in HDMI output makes it possible to show the screen on a projector or TV. This may be relevant in counseling sessions to help the client get a better understanding of the test results. It is also ideal for educational purposes, as students can easily follow the test results when displayed on a larger screen.
