Grason-Stadler AMTAS Pro™

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 Pro operates with a GSI AudioStar Pro™ or GSI Pello™ that is connected to a touch screen computer. This version offers diagnostic and screening testing for air and bone conduction with masking and speech SRT, WRS with masking. This test is self-paced and typically takes 15-20 minutes to complete and requires limited supervision. AMTAS Pro provides nine quality indicators and two reporting options.
