Auditory brainstem response (ABR) is a hearing test that checks how well the hearing nerve and brainstem respond to sound. It does not require you to say anything – you simply relax or sleep while earphones play sounds and sensors on your head measure the brain’s response.
Key facts
ABR testing is a standard part of newborn hearing screening in many countries. It is also used for adults when a regular hearing test is not possible.
Anyone may have an ABR test, especially newborns, young children, and adults who cannot reliably respond in a hearing booth. It is also used for people with suspected brainstem problems.
An ABR test is performed by an audiologist or a doctor. You lie down or sit comfortably, small sensors (electrodes) are placed on your head and behind your ears, and you wear earphones that play clicks or tones. The test measures the electrical signals from your hearing nerve and brainstem.
The test is painless. You will need to keep still and may even fall asleep. For babies, the test is often done while they sleep naturally or after mild sedation. It usually takes one to two hours.
If the ABR test detects hearing loss, treatment depends on the cause. Options range from hearing aids and cochlear implants to medical or surgical treatment for underlying conditions. Early intervention gives the best results.
For some types of hearing loss, doctors may recommend hearing aids, cochlear implants, or medication to treat infections or inflammation. Always follow your healthcare provider’s advice – never take medication without a prescription.
Surgery may be considered for conditions like otosclerosis (abnormal bone growth in the middle ear) or if a cochlear implant is needed. Your doctor will discuss the risks and benefits with you.
If you have hearing loss, using hearing aids or other devices can help you communicate. Learning lip reading or sign language may also be helpful. Many people find it useful to let friends and family know about their hearing needs.
A balanced diet and regular exercise support overall health, but they do not directly improve hearing. Staying active can help reduce the risk of conditions linked to hearing loss, like diabetes and heart disease.
Hearing loss can sometimes lead to feelings of isolation, frustration, or sadness. It is important to talk to a counsellor or a trusted friend if you feel this way. Support groups and mental health services can help.
Not all hearing loss can be prevented, but you can lower your risk by avoiding loud noise, treating ear infections promptly, and managing chronic conditions like diabetes.
Vaccines against illnesses such as meningitis, rubella, and mumps can prevent some causes of hearing loss.
Newborn hearing screening using ABR is common and helps detect hearing loss early, allowing for prompt treatment.
With early detection and proper treatment, most people with hearing loss can lead full, active lives. Many treatments are very effective, and support services are available to help you thrive.
