Minimum Effective Masking Levels in Threshold Audiometry. A procedure is described for masking during threshold audiometry. Illustrations are provided which show that use of an effective masking level equal to the threshold of the masked ear results in noise levels identical to those derived by the use of more complicated formulas.

Optionally, masking help can give a suggested masking level. The example here suggests 85 dB, but 75 dB is also within the safe masking range (Figure 8). Figure 8: 75 dB masking level is adequate, but 85 dB is suggested by the software. Amber indicates too much or too little masking, easier clarified by the suggested masking level (Figure 9).
Tinnitus pitch and minimum masking levels in different ...
https://pubmed.ncbi.nlm.nih.gov/24684405/
Tinnitus pitch and MML are etiology dependent. Objective: We sought to determine whether the results of audiological tests and tinnitus characteristics, particularly tinnitus pitch and minimum masking level (MML), depend on tinnitus etiology, and what other etiology-specific tinnitus characteristics there are. Design: The patients answered questions concerning tinnitus …
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
If the unmasked bone-conduction threshold is 10 dB better than the air-conduction threshold at that frequency in either ear, masking must be used. Because the threshold values on which the calibration of bone vibrators is based were measured with masking noise in the contralateral ear, the audiologist may prefer always to use masking in the testing procedure.

Step 1: Determine the starting levels. Step 2: Present the masking noise into the non-test ear, while simultaneously presenting the unmasked threshold (signal) into the test ear. Step 3: Increase the masking noise in the non-test ear by increments of 3 by 5 dB steps (+5dB, +5dB, +5dB). Step 4: If the tone is still heard after increasing the masking level three times, then that …

Rule 1: Masking is needed at any frequency where the difference between the left and right not-masked A/C thresholds is 40 dB or more when using supra- or circum-aural earphones or 55 dB or when using insert earphones Rule 2: Masking is needed at …

Determining the minimum masking level provides an approximate measure of how loud a patient perceives his/her tinnitus and can be used in subsequent tinnitus masking and sound therapies. Loudness discomfort level: The volume at which external sound becomes uncomfortable or painful for a tinnitus patient. This measurement informs the feasibility of sound therapy, …
Clinical Masking in Speech Audiometry: A Simplified ...
https://pubs.asha.org/doi/abs/10.1044/1059-0889%281999/019%29
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 ...
