How to Perform Masking in Audiology - eMoyo

A common issue with masking in audiometric testing is locating the masking plateau. This is called the masking dilemma and it occurs when there is moderate to severe bilateral conductive hearing loss. In this case, masking noise intensity presented in the non-test ear crosses over to the test ear and elevates the thresholds.

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.

The plateau method has been used for more than four decades. Nevertheless, in 2004 a different masking protocol was suggested, called the optimized method, to replace the plateau method in specific cases. Aim: To evaluate the feasibility of two clinical masking methods, plateau and optimized, in the testing of hearing thresholds.

For now, throw away those masking formulas and the Hood Plateau Method as in 2020 to mask or not to mask and effective masking have a very different meaning. COVID-19 has added a strange dimension to masking rules. It has changed what effective masking actually means to hearing healthcare providers. New Masking Rules for COVID 19

5. Continue this procedure until a plateau is observed – that is, when three consecutive 5-dB increases in masking are given without an observed shift in the response (threshold) of the Test Ear; 6. Record the masked threshold and the final level of masking used on the audiogram.

Modified Hood's Plateau Method Initial masking level = ACNTE (Air conduction of nontested ear) + correction factor (usually is the 10 dB "safety factor"). You start at a tone, then you raise the mask 5dB, if the patient can't hear the tone any more, than you raise the tone 5dB, they hear the tone again, so you raise the mask 5dB, if patient can ...

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 ...
