Hyperacusis: symptoms, treatment, and when to worry
Last updated September 3, 2026.
Hyperacusis is a reduced tolerance to everyday sounds: noises that others find normal, like dishes clattering or traffic, feel uncomfortably or even painfully loud. It can affect one or both ears and often travels with tinnitus. It is a real, recognized condition of how the brain and ear process sound, not oversensitivity in the personality sense.
Where does it come from?
It often follows a loud noise injury, arrives alongside tinnitus, or comes with conditions like migraine, certain ear disorders, or after head injury. Sometimes no clear cause is found. Sound tolerance lives in the brain's volume control as much as the ear itself, which is why hyperacusis can appear even when a hearing test looks normal, and why anxiety about sound can wind the problem up further.
What actually helps?
- Get an audiology assessment: hearing tests plus a sound tolerance workup confirm the diagnosis and rule out related problems.
- Resist the earplug habit: constantly blocking sound feels protective but turns the brain's volume up further. Ear protection is for genuinely loud environments only.
- Sound therapy: gradual, gentle re-exposure to low-level sound, often via wearable sound generators or a desk device, recalibrates tolerance over months. This is the core treatment.
- Counseling or CBT: addressing the fear and avoidance around sound directly improves outcomes, and it pairs naturally with sound therapy.
- Treat what travels with it: managing tinnitus, migraine, or jaw problems often improves sound tolerance as a side benefit.
When is it an emergency?
Hyperacusis itself is not an emergency, but one companion symptom is: sudden hearing loss in one ear over hours to days needs same-day or next-day assessment, because early treatment gives the best chance of recovery. Also get urgent review for sound sensitivity that arrives with facial weakness or numbness, severe spinning vertigo, or a bad one-sided headache.

Common questions
Why do normal sounds hurt my ears?
In hyperacusis the ear itself usually works fine; the problem is in how the brain's sound-processing circuits set the volume. Everyday sounds get amplified into uncomfortable or painful territory. It often follows noise injury, tinnitus, migraine, or head injury, and anxiety about sound can reinforce the gain. A hearing test can be completely normal, which confuses people until the tolerance tests are done.
Will hyperacusis go away?
For many people it improves substantially, especially with treatment. Sound therapy retrains tolerance over months, and cases triggered by a single noise event often settle as the system recovers. It tends not to vanish by sheer avoidance, though, and overprotection with earplugs actually keeps the sensitivity wound up, which is why guided re-exposure beats hiding from sound.
Should I wear earplugs all the time?
No, and this is the trap to avoid. Constant earplug use starves the auditory system of normal sound, and it responds by turning sensitivity up further. Reserve ear protection for genuinely loud settings like concerts, power tools, and motorbikes. The treatment direction is gentle, graded exposure to ordinary sound, not silence.
What is sound therapy for hyperacusis?
It means listening to low-level, comfortable sound for set periods each day, delivered by wearable generators, a bedside device, or an app, so the brain gradually recalibrates what counts as loud. The level is kept easy at first and increased slowly over months. It is typically run by an audiologist alongside counseling, and consistency matters more than intensity.
Is hyperacusis linked to tinnitus?
Closely. Many people with hyperacusis also have tinnitus, and the two share triggers like noise exposure. They are managed together, since sound therapy and counseling help both. If you have ringing plus painful sound sensitivity, mention both at the assessment, because the treatment plan covers them as a pair.
Can children have hyperacusis?
Yes, and it can look like bad behavior: covering ears at hand dryers, melting down in cafeterias, refusing noisy events. It also overlaps with conditions like autism where sensory sensitivity is common. A child who consistently finds ordinary sounds painful deserves an audiology assessment rather than discipline, and treatment is similar to adults, paced for the child.
