Rule 1: Masking is needed at any frequency where the difference between the left and right not-masked A/C thresholds is 40 dB or more when using supra- or circum-aural earphones or 55 dB or when using insert earphones

Channel 1 should be set to the left ear (test ear) using the preferred stimulus (usually tone). The masking frequency will automatically change along with the tone frequency when masking is turned on. You can set the masking and tone frequencies by …

The formula for deciding whether you should mask or not: Mask if the air-bone gap in the test ear ≥ 10 dB. How much masking is needed? To mask the non-test ear for for bone-conduction testing, add 10 dB HL to the air-conduction threshold in the non-test ear and add the occlusion effect (air conduction non-test ear + 10 dB HL + occlusion effect).

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.
Masking Rules for Hearing Care Professionals

New Masking Rules for COVID 19. The hierarchy of controls presented by the Center for Disease Control (CDC) to rid the virus and is included in at least three of these levels involves the use of masks to reduce the spread of the disease. Until recently, most hearing healthcare clinics and personnel simply considered masks as a method of ...

There was no need to do air conduction masking in this scenario (Rule 1 not required). Bone conduction was carried out on the worse ear: As the there was an air bone gap of >10dB between the air and bone conduction thresholds (Rule 2), bone conduction masking needed to be carried out at 0.5, 1, 2 and 4 kH Z. The left ear was the test ear using bone conduction, and the right ear …

If that value is greater than the IA, you need to mask. Example, if your SRT using traditional headphones is 50 dB in theTE and the best BC threshold in the NTE is 5 dB (50dB-5dB=45 dB), you need to mask since 45 dB is greater than 40 dB. ***Note: usually you have not yet performed BC when you are performing SRT, so assume air=bone.

Reveal Answer. You should find that the right hearing loss is conductive (BC thresholds in normal range). Rule three. Rule three of masking aims to find the true AC thresholds when a conductive hearing loss exists in the opposite ear.
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
Masking for diagnostic audiometry. Appropriate masking should be applied to the nontest ear when the air-conduction threshold obtained in the test ear exceeds the interaural attenuation to the nontest ear. Because the procedures for masking are not confined to pure-tone measures, these procedures are not discussed in this set of guidelines.

Defining Effective Masking EM definition – if masking noise of that level is in the ear, and the tone is put into the same ear at equal in intensity, you have masked. E.g. 50 dB EM masks 50 dB PT in SAME ear. So, if crossed over… if the tone crosses over at 10 dB HL, theoretically, putting in 10 dB E…
