Hearing Air Bone Gap

Image
An air bone gap may mean a problem in the outer or middle ear. For example if your audiogram showed an air conduction hearing loss of 70 db while your bone conduction test results only showed a 40 db hearing loss for a given test frequency then the difference between them in this case would be an air bone gap of 30 db 70 40 30.

A moderate air bone gap eg 30 db pta indicates some degree of conductive hearing loss.


Hearing air bone gap.

This audiogram shows a gap between the air conduction and the bone conduction thresholds however the bone conduction thresholds still indicate a hearing loss as they are not within normal limits.
The difference between the results of air conduction and bone conduction tests is known as the air bone gap.
In sensorineural hearing loss the thresholds for both air c…
