Featured Products
GSI AudioStar Pro
GSI AMTAS
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 is available in two versions, AMTAS Pro and AMTAS Flex.
Interacoustics vHIT - EyeSeeCam
Features: ~~The EyeSeeCam vHIT provides quick and objective measurements of the vestibular-ocular reflex (VOR). A simple tool to assess the performance of all 6 semicircular canals. The results allow the healthcare professional to efficiently diagnose the “dizzy” patient and evaluate if the dizziness is related to a vestibular disorder.
