Audiometer Calibration Equipment for Audiology Testing

Release time：2026.05.11 Views：14

Accurate audiometer calibration is essential for ensuring reliable hearing test results and maintaining compliance with international acoustic standards. Aihua Instruments provides professional audiometer calibration equipment, including sound calibrators, ear simulators, and acoustic couplers, designed for audiology laboratories, hearing aid manufacturers, hospitals, and acoustic testing institutions.

Why Audiometer Calibration Matters

Audiometers must be calibrated regularly to ensure accurate sound pressure levels and frequency response during hearing tests. Improper calibration can affect diagnostic accuracy and lead to unreliable hearing assessment results. Professional calibration equipment helps laboratories and medical institutions maintain compliance with IEC and ISO standards.

Frequently Asked Questions

What is audiometer calibration?

Audiometer calibration is the process of verifying and adjusting the output levels and frequency response of audiometers to ensure accurate hearing test results.

Why are ear simulators used in audiometer calibration?

Ear simulators replicate the acoustic impedance of the human ear and are used to accurately measure the sound pressure produced by audiometric earphones.

Which standards apply to audiometer calibration equipment?

Common standards include IEC 60942 for sound calibrators and IEC 60318 series standards for ear simulators and acoustic couplers.

How often should audiometers be calibrated?

Audiometers are typically calibrated annually, although daily listening checks and routine verification are also recommended.
