Features
High-precision simulation: Accurately simulates the acoustic characteristics of the human ear, ensuring reliable air conduction/bone conduction test results.
Simultaneously calibrates key parameters — hearing level zero, frequency response, harmonic distortion, masking noise level, and acoustic impedance — in full compliance with IEC 60645 (Audiometric equipment) and ISO 389 (Reference zero for calibration of audiometric equipment) series requirements.
Automated process: Computer-controlled signal generation, channel switching, parameter measurement, and data recording improve efficiency.
Guaranteed metrological accuracy: Standard microphone and force sensor meet mandatory verification requirements for medical equipment.

Mandatory Verification of Audiometric Equipment
A hearing threshold is only meaningful if the audiometer that measured it is telling the truth. Verify the earphones against a reference ear, not just the electronics against a meter.
