When there are differences between air conduction and bone conduction thresholds at the same frequencies in the same ear, we say that_________ exist.

A.) air bone gaps
B.) signal to noise ratio
C.) masking dilemmas
D.) shearing actions


A.) air bone gaps 

If air conduction thresholds and bone conduction thresholds are different? In this case, we could speak of the air-bone gap. Just like it sounds, this is the difference between air conduction thresholds and bone conduction thresholds. [Air conduction threshold (dB)] – [Bone conduction threshold (dB)] = Air-bone gap (dB).
