Audiometer calibration. Accuracy is essential when it comes to audiometer calibration. If a hearing loss is discovered the specific hearing loss data is e.g. used to set up a possible hearing aid. Many decisions – both legal and human – are based on this data and it is therefore very important that the audiometers are calibrated regularly. The GRAS audiometer Calibration …
Acoustic method for calibration of audiometric bone ...
https://pubmed.ncbi.nlm.nih.gov/22352496/
The standard method for the calibration of audiometric bone vibrators requires the use of an artificial mastoid, a device that converts vibratory energy to an electrical analog. The mechanical input impedance of the device is designed to represent the average mechanical impedance of the human head. For calibration purposes, it is not necessary that the coupling device represent …
Reference zero for the calibration of audiometric ...
https://pubmed.ncbi.nlm.nih.gov/16149243/
Intended as an input to international standardisation, this study investigated reference hearing thresholds for the calibration of audiometric equipment, which have been determined using 'clicks' as test signals, several kinds of earphones, and two types of transducers (a loudspeaker and a bone vibrator).

Schedule Calibration To ensure your patients are receiving the quality care they deserve, having your audiology equipment calibrated on a yearly basis is necessary. Regular audiometer calibration ensures the hearing level complies with strict values set by the American National Standards Institute (ANSI) or the manufacturer’s specific references for hearing thresholds.

An audiometer calibration kit can easily run five times the cost of the audiometer. Practically, only manufacturers and service providers doing many calibrations annually find it affordable to spend this much money on audiometer calibration equipment and to pay the cost associated with having that equipment calibrated annually.
