Audiometric Symbols - American Speech-Language …
https://www.asha.org/policy/GL1990-00006/
Audiometric symbols used to record the results of conventional pure tone threshold audiometry were suggested by ASHA ( 1974), following a review by the Committee on Audiologic Evaluation. Jerger ( 1976 ) has described further …

The symbol will appear in the audiogram as masked. There are many ways of applying clinical masking. Which one to use is your decision. Regardless of the masking method, use channel 2 to occupy the better ear. Step 7 To display the …
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’. Interaural attenuation

Masking Assignment One Measure a friend’s hearing Forehead bone unmasked: 250 – 4k Hz. Use forehead symbol Better ear (if there is one) bone unoccluded: 250 – 4k Hz. Typical symbol. Same ear bone with NTE occlusion with insert earphone. Retest, mark >O Each ear air conduction unmasked Do not stop at zero, establish threshold

Please note that that book has American PTA symbols, which are different to those used in the UK (BSA procedures), which might confuse the matter somewhat. ... Underlying theory of cross-hearing and masking The rules of masking example audiograms with accompanying videos of masking procedure runthrough on a patient simulator.
MASKING IN PURE TONE AUDIOMETRY - ENT Lectures

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
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.
Rule 3 explained? Masking Training with Tracy – Tracy ...
https://tjaudiology.com/rule-3-explained-some-tips/
A training or refresher course in masking in audiometry will enable audiologists to consider and understand why we need to mask, rather than just learning the rules. TJ Audiology Services uses audiometry simulation software to practice different scenarios, alongside interpretation of working audiogram.
Audiometry - Interacoustics

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

Steps in the Plateau Masking Approach to Air-Conduction Masking. 1 Recognize the need for masking. This implies that the non-test ear (better ear) has been tested first and the test ear’s (poorer ear’s) unmasked threshold has been obtained. 2 Set the initial masking level at 10 dB above the non-test ear threshold.
