One solution
Combining all of the diagnostic middle ear analyzer tests found on the AT235 and most of the features available on the popular AD229 diagnostic audiometer – makes the AA222 one of the most comprehensive combination of middle ear analyzer and diagnostic audiometer available today. Making it ideal for the new clinic, travelling to alternate locations and for clinical situations where space is at a premium.

The AA222 has testing capabilities for air and bone conduction as well as speech. Dual inputs for a tape or CD player allows the examiner to conduct binaural recorded speech tests and other tests for central auditory processing or hearing aid evaluations.

Other tests include pure tone and Stenger speech, ABLB, Auto Threshold (Hughson-Westlake method) and SISI. Outputs are available to connect external speakers and with an appropriate amplifier AA222 will produce 90dB or more of speech in a typical sound room environment. Separate software calibration for all transducers allows the exchange of insert phones or traditional TDH39 phones by the push of a button.

AA222h - High frequency and manual tympanometry
The AA222h provides additional high-frequency probe tones for Y-component testing in addition to the traditional 226Hz tone. With the push of a single button, the AA222h will switch to a 678, 800 or 1000 Hz probe tone. A tympanogram that is recorded using a high frequency probe tone (e.g. 1000 Hz) is considered more suitable for screening neonates.

Timeless design
The AA222 features a timeless design that fits the standards of a modern clinic today and tomorrow. It is designed with ergonomics and user-friendliness in mind. With the built-in power amplifier and test cavities it is easy and fast to set up and get started testing.
