  • Page 5: About The Aa222

    The AA222 is a device combining audiometry and tympanometry. The target population for the AA222 covers all ages. The AA222 is designed to be used only by skilled personnel such as audiologists, ENT surgeons, doctors, hearing healthcare professionals or personnel with a similar type and level of education.
