AMTAS™, or Automated Method for Testing Auditory Sensitivity, was created by audiologists, for audiologists. This tool is used to boost efficiency through a reliable and accurate method to obtain a diagnostic hearing test. While patients are working through AMTAS, the clinician can complete other tasks, such as counseling or additional testing. Once the patient has completed AMTAS, the clinician can then go over the results with the patient.


AMTAS Pro™ offers diagnostic air conduction, bone conduction, and speech (SRT and WRS) testing with masking. This self directed test typically takes about 15 minutes to complete and the report provides nine quality indicators to assist the clinician in interpretation of the accuracy of the test. AMTAS Pro is operated through a computer that is connected to a compatible GSI audiometer (i.e. AudioStar Pro or Pello).


Patients can use AMTAS Flex™ to obtain a validated hearing test before their appointment begins. AMTAS Flex is easy to use. The test is selfpaced so patients may proceed at a rate that is comfortable for them. This version of AMTAS allows patients to complete a pure tone screening or air conduction threshold test as soon as they walk in the door. Patented quality indicators ensure the validity and accuracy of the basic testing so you can move to the next step with confidence. AMTAS Flex is operated through a tablet computer with no audiometer required, making it the preferred option for portability.
