CALIBRATION METHOD FOR HEARING PROTECTION DEVICES

Abstract:

Embodiments relate generally to hearing protection devices which incorporate a calibration mode which allows the user to perform a calibration test to determine an individualized hearing threshold. Embodiments of the device may also comprise a normal mode to prevent input signals greater than the individualized hearing threshold from being transmitted to the user's ear canal. In addition, embodiments may comprise a normal mode configured to limit input signals to less than or equal to a standard industry threshold in the case no calibration test has been completed by the user. This may increase user comfort and prevent hearing damage.
