How Often do Audiometers Need to Be Calibrated?

Audiometers should be calibrated annually, along with all other diagnostic devices. This yearly calibration ensures that the equipment remains accurate and reliable and meets the standards set by the American National Standards Institute (ANSI) for precise hearing level measurements.

Regular instrument calibration is crucial for maintaining the standard of care your patients deserve and ensuring accurate results.


Factors like equipment age, wear and tear, usage frequency, exposure to extreme conditions, and handling can cause diagnostic instruments to become uncalibrated. Worn or aging components such as cables, jacks, and transducers can also affect test accuracy.

During calibration, our e3 Diagnostics technicians meticulously assess your diagnostic instruments and all related components, including transducers, cables, and wire connections. Upon completion, you'll receive a detailed condition report, ensuring your equipment is in optimal working order.
