Masking is not possible when the needed masking level results in ‘over masking’ at the same time: Air conduction Dial + (AC c – BC c ) – IaA ≥ Dial – (AC – BC) + IaA c

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.

Bone conduction pure tone audiometry In bone conduction pure tone audiometry masking for bone conduction assessment is required when there is a gap at any frequency of 15dB or more between the unmasked bone conduction result and the air conduction threshold. This is known as the air-bone gap. Masking in bone conduction testing

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.

For the mathematically oriented, the initial masking level (in dB HL) directed into the NTE may be reduced to the formula IML = HL N + MEMC + SF where HL N is the air-conduction threshold hearing level of the NTE, MEMC is the minimum effective masking correction, and SF is the safety factor.

When masking for speech and you are tying to work out if speech masking is required, the formula is PL - IA > Average BC(NTE). How will you calculate this if bone conduction is only tested on one ear? as in some cases there is no masking required for bone conduction as there is no air bone gap, which means you would normally only test bone conduction on one side.
