Do You Need a New Audiometer?

How is the old audiometer working these days?  Is it time for an upgrade? Speaking of upgrades, take a look at the Tremetrics RA 660 Audiometer-

This device is a combination:


Bio-Acoustic Simulator

HearCon Software

Optional – External Type 2 Microphone, (no booth, no problem)

This audiometer sells for $4,495.00. Add a second audiometer to the same location for $2,495.00.  Don’t have a booth, add the external Type 2 microphone for background noise monitoring for $1,195.00. The audiometer has the option to pause the test if the background noise levels exceed the allowable levels per the OSHA Standard.

With HearCon software (and if you already have Workplace Applications or HT Pro software), this audiometer works by showing the baseline and the live test results on the screen as the person is taking the test.

Tired of giving the same test instructions? Set the instructions to be presented to the individual prior to the start of testing under the headset, oh and you can set the instructions to be given in the language of your choice.

Are you testing in a mobile environment?  This audiometer can be used in a mobile environment with separate booths, or a single testing room with multiple audiometer stations.
