The Audio Traveller

The AA222 is the most comprehensive combi of middle ear analyzer and diagnostic audiometer available.
 
Combined from the best

AA222 combines all of the diagnostic middle ear analyzer tests found on the AT235 and most of the features available on our popular AD629 diagnostic audiometer. This makes the AA222 ideal for the new clinic, for travelling to alternate locations, and for clinical situations where space is at a premium.

  • Audiometry

    The AA222 has testing capabilities for air and bone conduction as well as speech. Dual inputs for a tape or CD player allow the examiner to conduct binaural recorded speech tests and other competing message 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 with the push of a button.
     
  • Tympanometry

    Perfect method for obtaining a tympanogram on crying children or difficult to test patients when physical sealing is difficult. An automatic adaptive pump speed produces tympanograms with high peak resolution without sacrificing test time.

    With the push of one button you can extend the pressure range from +300 daPa to �600 daPa. Switch between left or right ears for labeling tests with the push button. Another button labeled "child" automatically produces a moving "choo-choo train" as a visual distracter for the child. 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 which is considered more suitable for screening neonates.
