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.

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 initial masking level formula for bone-conduction testing accounts for the OE, and may be written as. IML + HL N + MEMC + SF + OE. Determining the Occlusion Effect. We need to know the size of the OE to determine the IML.

For now, throw away those masking formulas and the Hood Plateau Method as in 2020 to mask or not to mask and effective masking have a very different meaning. COVID-19 has added a strange dimension to masking rules. It has changed what effective masking actually means to hearing healthcare providers. New Masking Rules for COVID 19

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.

17. How much noise? If you’ve determined the need for masking, add 10 dB to the SRT of the non-test ear + an extra 15 dB for your plateau. So… Noise in NTE = SRT of NTE + 25 dB Ex:The SRT of the NTE is 30 dB, so you add 25 dB to arrive at …

Masking: Pure and Simple. by Hilary on January 4, 2022. Thorough, detailed explanations of masking principles (such as why and when to mask), as well as the different factors affecting true threshold (i.e., under-masking, over-masking, etc.). Appreciated the insight as to what type of noise is most effective.
