PURE TOME 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. You will indicate when you hear a tone by pushing a button or raising your hand.

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. This is helpful in determining if your hearing difficulty is due to a problem with the middle ear, such as an ear infection, or with the inner ear, which may be due to aging, noise exposure, or a variety of other causes.
