1. Select initial amount of masking for the non-test ear (i.e., air-conducted threshold of the non-test ear (AC Nontest + 10 dB HL), plus correction factor for occlusion effect, if applicable ; 2. Re-establish threshold in the test ear with this initial amount of masking (e.g., AC Nontest Ear+10); 3.

The formula for determining whether masking is needed: Mask if: AC (test ear) – IA (40 dB or 60 dB) ≥ BC (non-test ear). Generally speaking, audiologists determine when to mask by comparing the air-conduction thresholds of the test ear and the non-test ear.
