Distribution Characteristics of Air-Bone Gaps: Evidence of ...
https://pubmed.ncbi.nlm.nih.gov/26627469/
Manual audiometry produced air-bone gaps that were not normally distributed and show evidence of biasing effects of assumptions of expected results. In one database, the form of the distributions showed evidence of inclusion of conductive hearing losses.

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).

Air-bone gaps from manual audiometry (squares) by an expert audiologist and the predicted distribution from Figure 3 (triangles) are shown. There are more air-bone gaps of 0 and 5 dB and fewer of -5, -10, and -15 in the manually-obtained audiograms compared to …

https://pubmed.ncbi.nlm.nih.gov/17727085/
The data are consistent with the hypothesis that a large vestibular aqueduct introduces a third mobile window into the inner ear, which can produce an air-bone gap by 1) shunting air-conducted sound away from the cochlea, thus elevating air conduction thresholds, and 2) increasing the difference in impedance between the scala vestibuli side and the scala tympani …

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7224429/
An air-bone gap (ABG) is defined as the difference between air-conduction and bone-conduction audiometric thresholds. ABGs are found in patients with conductive (CHL) or mixed (MHL) hearing loss generally attributed to outer- and/or middle-ear diseases such as otitis externa, tympanic membrane perforation, interruption or fixation of the ossicular chain, and chronic …

Dr. Christopher Smith answered. Family Medicine 41 years experience. Hearing problem: air/ bone gap is the difference between hearing through the air---or hearing through bone vibration the Gap is the difference between them. If there is a difference this indicates problems in your outer or middle ear. this could be wax,hole in ear drum,fluid behind the ear or damage to …
What does an air bone gap tell you? - FindAnyAnswer.com
https://findanyanswer.com/what-does-an-air-bone-gap-tell-you
The difference between the results of air conduction and bone conduction tests is known as the air-bone gap. An air-bone gap may mean a problem in the outer or middle ear. If there is no gap between air and bone conduction this may indicate a problem in the inner ear (cochlea). Beside above, how much of an air bone gap is considered significant? The air-bone …
