AUDIOMETRIC EQUIPMENT CALIBRATION

Your local GSI partners can provide you with everything you need in calibration services.

Why is calibration important?

Calibration is important to ensure that testing is as accurate as possible. Over time, periodical checks are required to keep audiometric equipment operating consistently. It is recommended that users calibrate their equipment at least annually, but many clinics calibrate as frequently as quarterly due to heavy use of the equipment. Your local technician will be able to answer any questions that you may have about a proper calibration schedule.

How does calibration work?

For audiometers, a technician will perform an acoustical calibration. They will attach a transducer to a coupler or artificial ear and compare the SPL to a known standard (such as ANSI S3.6 2018, ISO). This process verifies that the transducers that are used in testing are calibrated to the piece of equipment that is being used. It is not recommended to swap transducers for testing, as the transducers that are tested by the technician will be calibrated to that specific piece of equipment.

For tympanometers, the coupling method is similar. The difference with tympanometers is that the pressure systems will need to be checked for potential leaks to ensure that the output is correct. The technician will then do cavity checks to make sure the volumes are correct. Finally, a probe tip check is necessary to make sure it is free of debris.

For OAE and ABR devices, an ear simulator is used to verify that the device is outputting the correct stimuli. Similar to tympanometer calibration, a thorough cleaning of the probe is required to ensure there is not any debris that is affecting the test process. The microphone is also tested to make sure it is reading the correct level.
