Because the procedures for masking are not confined to pure-tone measures, these procedures are not discussed in this set of guidelines.

Generally accepted masking rule for BC, if there is an air-bone gap (ABG) within the tested ear …

WebAn air-bone gap is apparent when air-conduction and bone-conduction thresholds do not match each other, because air-conduction yields poorer results compared to bone-conduction thresholds. (Therefore, air-bone gap = AC test ear – unmasked bone-conduction.) The rule for contralateral masking can be expressed simply as: Air-bone … WebA pure tone was used to mask narrow and wide bands of noise centered on the frequency of the tone.

WebEach subject had no hearing in one ear following translabyrinthine surgery for removal of an acoustic neuroma. The opposite ear had hearing thresholds better than 40 dB HL and an air-bone gap of less than 10 dB at any audiometric frequency. Pure tone air-conduction thresholds were obtained in the range 0.25-8 kHz.
