How to Mask For Air and Bone Conduction Testing 1. Select the initial amount of masking for the non test ear - threshold of the non-test ear by air conduction plus 10dB HL. 2. Re-establish threshold in the test ear with this initial amount of masking in the non- test ear. 3.

WHEN TO MASK? “MASKING RULES” First rule: (BC masking rule) In masking, the order is reversed to the PTA testing, we start by looking for whether BC masking is needed or not. This should be done because determining when masking is needed for AC depends on knowing the true BC thresholds

Also, when required, appropriate masking is used. For special purposes, extended high-frequency audiometry may be used for frequencies of 9000 to 16000 Hz. Pure-tone threshold audiometry is used for both diagnostic and monitoring purposes. Return to Top Scope
