How to Perform Masking in Audiology - eMoyo
https://blog.emoyo.tech/content/masking-in-audiology
In audiology, masking means playing white noise in the non-test ear, to prevent it from hearing the tones that cross over from the test ear. It helps to obtain the true threshold of the test ear and ensures that the non-test ear is not ‘assisting’.

Figure 4: Masking noise should be louder. Purple indicates that masking is needed but non-feasible (Figure 5). Figure 5: Masking non-feasible. Caveats (1) Be aware that patients need proper instructions before audiometry with masking is undertaken. (2) The switching-on-and-off of the masking noise may be uncomfortable to some patients and cause ...

establish the threshold was recommended. The masking level should be increased in 10 dB steps until the measured threshold “remains constant with further additional incremental steps of 10 dB” (Hood, 1960, p. 1227). Yacullo (1996) recommended the masking level be “increased over a range of at least 15 to 20 dB” (p.

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
Naunton's Masking Dilemma Revisited
https://pubmed.ncbi.nlm.nih.gov/30531635/
Paradoxically, over masking occurs when the intensity of the required masking noise to the contralateral ear is such that it exceeds interaural cranial attenuation by an amount sufficient to mask the test ear. Ralph F Naunton was the first to describe this phenomenon, which has since been known as "Naunton's masking dilemma."

Answer: There related to the amount of masking it takes to isolate the NTE and TE from responding for each other during air, bone and speech testing. Analogy- Think of goldilocks and the three bears, one is too little, one is too big, and one is just right! Under Masking- …

When to Mask - Bone Conduction When there is a 15dB or more difference between the air conduction threshold of the test ear and the bone conduction threshold of the same ear aka: Mask for BC when there is an air-bone gap. 10. Types of Masking Noise Puretone Testing The masker is a narrow-band noise (NBN) that is centered around the test ...
Masking on hearing testing - Dizziness-and-Balance.com

Masking Dilemma. This situation occurs when there is a conductive type hearing loss in both ears, which is moderate to severe. The dilemma is that an adequate intensity to mask the non-test ear crosses over to the testing ear and invalidates the thresholds. Enough masking is too much masking. There are several "work arounds" to this.
Formula Masking #1 - AudSim

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…
Clinical Masking | Ento Key
https://entokey.com/clinical-masking/
Clinical masking is an application of the masking phenomenon used to alleviate cross-hearing. In clinical masking we put noise into the nontest ear because we want to assess the hearing of the test ear. In other words, the masking noise goes into the NTE, and the test signal goes into the TE.
