The air-bone gaps are zero at all four frequencies in both the right ear and left ear, which is a total of eight frequencies. In reality, the probability that the air-bone gaps are zero at four frequencies is about two in a thousand, and the probability that all eight air-bone gaps are zero is four in a million.

This could be something such as wax (or “junk”) in your ear canal blocking incoming sounds, a hole or other problem in your eardrum, fluid in your middle ear, damage to your middle ear bones (for example—otosclerosis), etc. That is why if there is an air-bone gap you typically want to see an ear specialist to find out why.

Results: Automated audiometry produced air-bone gaps that were normally distributed suggesting that air- and bone-conduction thresholds are normally distributed. Manual audiometry produced air-bone gaps that were not normally distributed and show evidence of biasing effects of assumptions of expected results.

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 …

INTRODUCTION. 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 …

Audiometry relies on techniques similar to the Weber and Rinne tests to compare air and bone conduction. Bone conduction audiometry measures pure-tone thresholds using a mechanical device that...

The air-bone gap (ABG) should be at least 10 db. This audiogram is due to tympanosclerosis (see below). The Carhart notch, an audiological finding mainly of historical importance, is a dip at 2000 hz in bone conduction without a corresponding dip in air conduction. Similarly, you may ask, what causes air bone gap?
