Bone conduction audiometry is used for diagnostic purposes and is instrumental in identifying sensorineural hearing loss. Proper differentiation between conductive and sensorineural hearing loss is to compare hearing threshold levels from both air conduction and bone conduction audiograms. Audiologist, ENTs and other hearing specialists rely on air and bone conduction …

The audiometeris an electric instrument consisting of a pure tone generator, a bone conduction oscillator for measuring cochlear function, an attenuator for varying loudness, a microphone for speech testing, and earphones for air conduction testing.
Pure Tone Air & Bone Conduction Audiometry
https://www.wnhcares.org/getpage.php?name=pure_tone
Bone Conduction audiometry is conducted by placing a bone oscillator behind the ear instead of using headphones. The bone oscillator transmits sound through bone vibration to the cochlea or inner ear, bypassing the middle and outer ear.

Bone conduction audiometry sends vibrations via a bone oscillator directly to the inner ear, so bone conduction thresholds should be equal to or better than air conduction thresholds in the same ear. Bone conduction thresholds are often marked with an < for the right side or an > for the left side.
Audiometry: MedlinePlus Medical Encyclopedia

A device called a bone oscillator is placed against the mastoid bone to test bone conduction. Speech audiometry -- This tests your ability to detect and repeat spoken words at different volumes heard through a head set. Immittance audiometry -- This test measures the function of the ear drum and the flow of sound through the middle ear.

Bone conduction testing is important in helping to determine the type of hearing loss that a patient may have. If the test results from the pure-tone test and bone conduction are the same or very close then a sensorineural hearing loss is present, however, if the test results from both tests are far apart then a conductive hearing loss may be present and further investigation as to …
