Occupational Safety and Health Administration (OSHA) requires a daily calibration check before audiometric testing of employees. You can complete this procedure with a reliable test subject or by using a machine like the Tremetrics Oscar 6.
The Oscar 6 substitutes for a reliable test subject and quickly generates an audiometer compliance check as a legal document. This procedure ensures that your audiometer is currently in calibration compliance with OSHA requirements. More importantly, it provides a "stable hearing threshold," ensuring that each hearing test you conduct yields consistent results every time.
The Oscar 6 accommodates all audiometric and standard earphones and is compatible with most audiometers in today's market.
When running your daily calibration check, you may occasionally encounter a "Daily Calibration Failure." This error is usually easy to identify and correct. When encountering this error, here are three quick troubleshooting tips to try.
- Check to make sure that the headset is placed on the box securely. The ear cups should securely fit onto the color-coded earphone couplers. You will get an error if they are not put onto the couplers securely. Adjust and rerun the daily calibration test.
- Inspect ear cushions to ensure they are not swollen, cracked, or "mushroom shaped." Ear cushions can become damaged over time, which can cause a poor fit onto the couplers. If any of these signs of damage are present, you may need new earphone cushions.
To help maintain your earphones, never wipe them with a liquid disinfectant. You can use alcohol-free wipes which are safer than other commercial disinfectants, but ideally earphone covers are the best solution for hygiene and maintenance.
An important note: a technician must re-calibrate your audiometer if you need to replace your earphone transducers.
- Check for loose cords on your headset. Lots of testing and movement will eventually cause cord connections to fail. You may have a problem with either the cord or the headset itself. Check out this 30-second video to learn more and avoid an unnecessary service call.
If your earphones break or need replacing, a technician must re-calibrate your audiometer.
