OSCAR7™ Electro-Acoustic Ear

OSCAR 7™ Electro-Acoustic Ear & Octave Monitor

Verify that sound levels in your testing environment are within accepted levels

The daily biological check for audiometers and sound room monitoring are combined in the new Tremetrics OSCAR 7 Electro-Acoustic Ear & Octave Monitor. This dual-function instrument will operate in a continuous monitoring mode, pausing the test if noise levels in the hearing test enclosure exceed accepted levels. Switch to Daily Biological mode and OSCAR 7 acts as a substitute test subject with a known hearing threshold level to provide a daily legal record of your audiometer's calibration compliance. Color-coded earphone couplers accommodate all standard earphone enclosures and help ensure accurate testing. The OSCAR 7 also features the patent-pending ID Wizard™ which automatically verifies compliance using the new Tremetrics HT Wizard audiometer.
