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’.

Just like masking for puretones Determine the need for masking and use plateau method to determine effectively masked threshold for speech Consider the interaural attenuation (IA): 40 dB for headphones 70 dB for inserts 0 dB for bone (you probably won’t do a bone-conducted speech test, though it is possible and very useful in children) The same rules apply …

Masking can be applied to air conduction, bone conduction, and speech audiometry. Interaural attenuation The need to mask the better hearing ear is linked to the interaural attenuation, which equals the amount of attenuation the sound is exposed to on its way through the skull.

The optimal masking level during speech audiometry is one that falls above the minimum and below the maximum masking levels. The goal is to select a masking level that falls at the middle of the masking plateau. This article presents a simplified approach to selecting an appropriate level of contralateral masking during suprathreshold speech audiometry.
MASKING IN PURE TONE AUDIOMETRY - ENT Lectures

This refers to the inability of the brain to identify a tone in the presence of masking, even when they are heard in opposite ears; hence masking is occurring centrally rather than peripherally (in the cochlea). Central masking is a phenomenon that occurs beyond the ear, during central auditory processing.

As a reminder about speech recognition testing, masking is frequently needed because the test is being presented at a level above threshold, in many cases well above the threshold. Masking will always be needed for suprathreshold testing when the presentation level in the test ear is 40 dB or greater above the best bone conduction threshold in ...
Speech Masking : audiology
https://www.reddit.com/r/audiology/comments/j7wzgv/speech_masking/
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.

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…

Contralateral masking is indicated during speech audiometry whenever the presentation level of the speech signal (in dB HL) in the test ear (Presentation Level test ear) equals or exceeds the best pure tone bone-conduction threshold in the nontest ear (Best BC Nontest Ear) by a conservative estimate of IA.
