Auditory Brainstem Response (ABR) testing is frequently used to screen newborns for hearing problems. It measures the response of a baby’s hearing nerve using electrodes. This can also be used in children who are unable to complete hearing testing in ordinary circumstances, either they are just too young, or don’t respond accurately in the audiology booth. Infants can be done in the office. Older kids sometimes require sedation.
An auditory brainstem response (ABR) provides the audiologist with information on a child’s inner ear and the neuronal pathway that connects the ear to the brain. Electrodes are placed on the child’s head to record brain activity in response to sounds.
Otoacoustic Emissions (OAE) testing uses a microphone and earphone to calculate an infant’s hearing abilities by measuring the reflection of a sound’s echo as it passes through the ear canal. Otoacoustic emissions are the sounds given off by the inner ear when stimulated by sound.
This test is used to determine if there is damage to the hair cells that line the cochlea. Since the emissions are nearly inaudible, a small plug is placed into the ear in order to detect the ear’s reaction to a series of clicks.
This test is objective, making it is a useful addition to newborn hearing screenings. OAE’s are quick, painless, and can almost always be done without sedation.
Tympanometry is a test of the middle ear used to detect fluid, wax buildup, eardrum perforations and tumors. It measures movement of the eardrum in response to air pressure; the results are recorded on a chart called a tympanogram.
Audiometry – This is hearing testing conducted in a sound booth with pure auditory tones. At a young age (3 or younger), sometimes we can only identify the hearing the best side. Often we can accurately measure the hearing across the sound spectrum for each specific ear. W can often differentiate between conductive and sensorineural hearing loss using this method.
Speech Threshold testing – Speech recognition threshold (SRT) and speech awareness threshold (SAT) testing can help with verifying an audio gram and also help determine how well a hearing loss impacts function.
