Audiometry/Hearing Conservation

Tremetrics RA800 Interactive Touch Audiometer

Easy-Touch Audiometer

The RA800 is Tremetrics’ new interactive touch-screen interface that makes your testing faster and more convenient than ever before. Touch-entry is easy and natural.

The users simply touch their finger to the screen to select the desired operation or function display. The touch-screen capability offers the ability to customize the program and the subject questions and answers right on the screen. Once data has been entered, the data is stored on a drop down menu on the screen and can be activated with a touch. Touch to select an answer, touch to start a test, touch to print out an archival-quality audiogram. It really is that easy!

Accurate results every time

The goal of any good hearing conservation program is the timely identification of those employees who may be experiencing a hearing loss due to work-related noise exposure. The RA800 provides one of the key elements for building a highly successful program.

The versatile RA800 tests from -10 to 100 dB and from 250 Hz through 8000 Hz. The accuracy and repeatability of the testing methodology is based on experience gained from providing thousands of audiometers for industry and government testing programs. The audiometer uses the accepted modified HughsonWestlake test paradigm, with a fully automated test routine or the choice to test manually or semiautomatically for just one selected ear/frequency or several.

The RA800 incorporates sophisticated retest and validation checking to ensure that proper hearing threshold levels are determined and includes built-in safeguards to alert the operator if individuals are attempting to manipulate test results.
