WebSteps for Finding Bone-Conduction Maximum Masking Level (MMax) 1 Calculate MMax: lowest anticipated bone conduction threshold + 45 dB. 2 Check that you are not undermasking. Undermasking is a problem when the measured BC threshold is higher than estimated. Calculate MMin once you know the bone-conduction threshold. WebProcedures are described for manual pure-tone audiometry, using both air-conduction (a-c) and bone-conduction (b-c) testing, with and without masking. The document does not cover high-frequency audiometry (>8000 Hz), screening audiometry, use of short-duration tone bursts, self-recording audiometry or sound-field audiometry. 4. canine health record template
