Why you should always calibrate an audiometer?

Regulations and standards that cover the use of audiometers exist globally. While some differ, most, if not all, require that the equipment is calibrated and maintained regularly and records are kept for auditing.

The Occupational Safety and Health (OSHA), The American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) insist on having equipment calibrated and checked on a routine basis.

Therefore, everyone must calibrate audiometers to ensure that they comply with their country/state’s regulations and ensure testing accuracy.
