Perform air conduction audiometry unmasked for both ears. Step 2 Perform bone conduction audiometry unmasked for both ears. Step 3 Apply masking if needed: (1) In case of an air-bone gap of 15 dB or more, you must reassess the bone conduction threshold while applying masking to the non-test ear.

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 any frequency where the not-masked b …

1. Select initial amount of masking for the non-test ear (i.e., air-conducted threshold of the non-test ear (AC Nontest + 10 dB HL), plus correction factor for occlusion effect, if applicable ; 2. Re-establish threshold in the test ear with this initial amount of masking (e.g., AC Nontest Ear+10); 3.
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
Masking for diagnostic audiometry. Appropriate masking should be applied to the nontest ear when the air-conduction threshold obtained in the test ear exceeds the interaural attenuation to the nontest ear. Because the procedures for masking are not confined to pure-tone measures, these procedures are not discussed in this set of guidelines.

Masking. While entirely optional, effective masking levels could be recorded on the audiogram for both air conduction and bone conduction thresholds, depending upon individual preference. When this policy is followed, the maximum effective masking level used to obtain threshold at each frequency should be recorded.

Masking noise is sometimes used in the nontest ear to prevent its participation in the test. The audiogram is a graph depicting hearing thresholds in decibels on the ordinate and frequency in hertz on the abscissa. The symbols in Figure 133.1are used to plot thresholds for pure-tone air and bone conduction testing.
