This effect arises across the frequency range and is related to the resonance properties of the ossicular chain. The result is a “notch” in the bone conduction audiogram which is more pronounced at 2 kHz as described by Carhart in 1950. References Carhart, R. (1950) Clinical application of bone conduction audiometry.

Audiogram in airconduction shows a decrease in air conduction at all frequencies. Carharts notch 2 is actually a decrease in bone conduction of 10-15 dB seen around 2 kHz frequency. Bone conduction actually means sensorineural reserve. After successful stapes surgery the carharts notch disappears when the conductive hearing improves.
Why does Carhart's Notch occur?

The Carhart notch is a depression in the bone-conduction audiogram of patients with clinical otosclerosis. The middle frequencies from 0.5 to 2 kHz, which correspond to the resonance frequency of the middle ear, can be substantially improved following successful stapes surgery. Similarly, is otosclerosis serious?
