Grason-Stadler AMTAS Flex™

GSI AMTAS™ is the only patient-directed evaluation tool that uses patented test methods and accuracy algorithms to perform diagnostic or screening audiometry. AMTAS was created to free up the busy clinician and boost efficiency in daily workflow by providing a reliable and accurate way to obtain a basic diagnostic hearing test. AMTAS is different than other automated tests; it provides quality indicators, classification of audiometric findings and clinician and patient reports. Numerous peer-reviewed, comprehensive studies have been conducted to bring proven validity to this reliable method of testing.

AMTAS Flex is a stand-alone test that uses a tablet with no audiometer required. Flex offers screening and diagnostic air conduction audiometry. The screening test typically takes 1-2 minutes to complete. Diagnostic testing obtains pure tone thresholds in about 10-15 minutes. The diagnostic test provides up to six quality indicators and two reporting options.
