Pure Tone Testing
Pure-tone testing (also known as pure tone audiometry) uses air conduction to measure your ability to hear sounds of various pitches and volumes. You will be asked to identify a series of tones by raising a hand, pressing a button, or responding verbally.
Bone Conduction Testing
Bone conduction testing is another type of pure-tone test that measures the inner ear’s response to sound. If there is damage or a blockage in the outer or middle ear, bone conduction audiometry testing may be used.
Instead of sending the tones through the ear, this type of testing is able to bypass the outer and middle ear and send the tone directly to the inner ear. A small vibrator is placed behind the ear. The device sends out a vibration that passes through the skull bone to reach the inner ear.
Speech testing is used to measure your speech reception threshold (SRT), or the faintest speech you can understand. Your ability to recognize words at a comfortable listening level is then measured.
Tympanometry is a test of the middle ear used to detect fluid, wax buildup, eardrum perforations. It measures movement of the eardrum in response to air pressure; the results are recorded on a chart called a tympanogram.
Acoustic Reflex Testing
The acoustic reflex test measures involuntary muscle contractions of the middle ear and is used to determine the location of your hearing problem (the ossicles, cochlea, auditory nerve, etc.) as well as the type of hearing loss.
Otoacoustic Emissions (OAEs)
Otoacoustic emissions (OAEs) are sounds generated by vibrations of the hair cells in the cochlea of the inner ear. This test helps determine whether there is a blockage in the ear canal, excess fluid in the middle ear or damage to the hair cells of the cochlea. OAE testing is often included in newborn hearing screening programs.
