Every audiometer must be electronically calibrated to ANSI standards at least once a year by an independent firm with specialized equipment and trained staff. 

Options for Calibration

Calibration by the Manufacturer

Calibration by an independent firm- you must either ship it to them or schedule for a service technician to come to you. 

Request the list of Calibration companies registered by the State of Texas to calibrate audiometers for use in Texas via email at vhssprogram@dshs.texas.gov.

Process for performing an annual electronic calibration: 

1. When shipping, pack the audiometer carefully to protect it from damage in transit. 
2. Include a list of any problems you discover while using the audiometer. 
3. The firm will provide results on a form that should be kept with the audiometer. 
4. As soon as the audiometer is returned, the user should perform a biological check to re-establish new baseline hearing records for three people, as outlined previously.

What to confirm after calibration 

• Calibration Certificate 
• Calibration Sticker
