Additional features:* viewing tests results,* adding notes to tests results,* printing of the tests results,* adjustment of calibration (calibration coefficients may be adjusted on the basis of your audiogram produced using an audiometer).* verification of calibration coefficients,* suppressing of the masking noise for the purpose of free field audiometry.
