GSI AudioStar Pro

Grason-Stadler AudioStar Pro™

The GSI AudioStar Pro is a versatile, two-channel clinical audiometer that can be used for complete audiometric test evaluations on patients of all ages.

With configurable tests and preferences, including built-in word list wave files and special tests like Quick SIN and TEN Test, the AudioStar Pro is fully customizable for efficient and consistent testing.

The GSI AudioStar Pro now comes with new hardware, firmware, and a new OS. The device provides features such as a higher resolution screen, centering option for VRA, independent store buttons, the ability to save more than six speech scores per session, masking level indicators, and a power on time less than a minute.


Testing Enhancements:

  • Single Pure Tone - There is no longer a designated high frequency button, standard and high frequency testing may be performed in the same test type.
  • Channel Specific Store Buttons - Now you may record on the left or right audiogram with the push of a designated button.
  • Centering VRA - The AudioStar Pro now has a dedicated button for a centering toy.
  • Simultaneous Processes - You may now use different transducers in separate channels at the same time, plus talk forward and change test types simultaneously.


Data Enhancements:

  • Reload Cached Sessions - New updates give you the ability to load previous testing sessions for review and editing.
  • Export to USB - Export all testing data to a USB drive to save testing results in your preferred format.
  • New Configuration on Loaded Sessions - New settings are implemented when you clear a session, eliminating the need to restart the system.
