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 …

Pure tones (single frequencies) are used to test air and bone conduction. These and speech testing are done with an audiometer. The audiometer is 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.

Audiometry. An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone). Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain. Sound waves can travel to the inner ear through the ear canal, eardrum, …

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.

Pure Tone Air & Bone Conduction Audiometry A basic pure tone hearing test checks your ability to hear tones of different pitches in each ear. Soft foam earphones will be inserted into your ear canals, and will deliver a series of tones into the ears. The tones will vary in pitch and loudness. Each ear is tested individually.

The presence of an air-bone gap signifies conductive hearing loss. The dynamic range between the threshold of hearing and loudness discomfort level is around 100 dB in normal hearing listeners. Listeners with sensory hearing loss have raised hearing thresholds, but their loudness discomfort levels are essentially similar to those of normal hearing listeners.

When symmetrical air conduction thresholds are obtained, and there are no differences between these thresholds and the unmasked bone conduction threshold (i.e., symmetrical sensorineural hearing loss), then it is sufficient to record only the air conduction thresholds and the unmasked bone conduction thresholds. An example is shown in Figure 3.
