HT Wizard Easy-Touch Audiometer

Touch the future of hearing testing

Download Spec Sheet

Take your hearing testing program into the new millennium in one easy step. A touch-screen user interface and built-in OSHA compliance features are combined in the most effective automated hearing testing system ever developed -- the Tremetrics HT Wizard.

The Wizard audiometer features a large, easy-touch color display that conveniently adapts to any testing height and allows full-screen monitoring of real-time test data. To streamline data entry, customized subject questions and answers can be entered right on the screen. Operators enter data just once and the choices are then stored in convenient drop-down lists that activate with a touch. When it's time to test, the user simply touches the screen to start and spoken auto-test instructions are given in a choice of one of seven languages. This allows each subject to more confidently respond to the test tones, and assures a more reliable measure of their hearing acuity.

A host of time-saving features also help ensure OSHA compliance. The new patent-pending ID Wizard™ verifies and documents that all the earphone, handswitch, and OSCAR™ cables are correctly connected. Additionally, a daily Biological Log is automatically updated and can be printed out on demand. Comprehensive information on a particular audiometer and its calibration records are available at a touch of the display.

Up to 2,000 audiometric records can be stored, making the Wizard infinitely mobile and allowing comprehensive testing at any location. In addition, the audiometer will automatically calculate threshold shifts and PBI and provide instant archive-quality audiogram records via the quiet, built-in printer. For data transfer, an RS232C interface provides remote batch capability or serves as a direct link to mainframe computers or PC-based data management software such as Tremetrics FOSHM™.
