Understanding Your Audiometer Calibration Certificate

1 December 2025

What is an Audiometer Calibration Certificate?

An Audiometer Calibration Certificate serves as official proof that your audiometer has been thoroughly tested and calibrated in line with recognized industry standards. It includes essential details such as the device’s model, serial number, and the date the calibration took place. Receiving this certificate assures you that your equipment is functioning accurately and complies with necessary regulations.

Why Does Annual Calibration Matter?

Annual calibration is necessary to keep your audiometer performing reliably and ensures it aligns with the requirements established by the American National Standards Institute (ANSI) for precise hearing level assessments. Routine calibration not only upholds the quality of care you provide but also guarantees the accuracy of your results for every test subject.
