Overmasking may be occurring If BC threshold + 45 < MMax For example, if you guessed a 20 dB HL bone-conduction threshold, which gives you the Mmax calculation of 65 dB EM, and the real threshold is 10 dB HL, you may have overmasked. 10 dB BC threshold + 45 = 55 which is lower than your MMax level of 65 dB EM.

The Masking Dilemma In bilateral, conductive hearing losses, the amount of masking noise required is often sufficient to result in overmasking and a shifting of the true threshold. In these cases, it is best to record the unmasked thresholds and note below the audiogram, “could not mask-masking dilemma” 17.
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." Methods:

Overmasking is commonly encountered in patients with bilateral conductive hearing loss. In such patients, in order to provide 40-dB masking above the BC threshold in the nontest ear, the masking level may exceed interaural attenuation and produce an inadvertent threshold elevation by masking the test ear, as well.

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.

Over Masking- too much masking-the threshold of the patient is raised 10+ dB shift over the plateau Central Masking: 5 dB shift (worse threshold now) due to the person’s CNS central nervous system. This has to do with the functioning of the brain receiving extra stimulus in both ears at once and must process what is happening.

How do you mask? : audiology - reddit

Overmasking is the situation where your masking noise is so loud that it crosses over and interferes with the test ear. This is an extremely rare occurrence. To figure out if you are overmasking, add the intra-aural attenuation of your transducer to the masked threshold (or suspected masked threshold) of the test ear.
