Quick Answer
Hyperacusis, also called decreased sound tolerance, is a condition in which everyday noises such as running water, turning pages, appliances, car engines or conversation feel unbearably loud or painful. It is associated with tinnitus, Williams syndrome, autism, migraines and Lyme disease. Main treatments include sound therapy, cognitive behavioral therapy (CBT) and tinnitus retraining therapy (TRT). [1]
What the research says
There is still no agreed definition or objective test for hyperacusis. A scoping review identified 3,343 papers on electrophysiological measures of hyperacusis and analyzed 35 of them, concluding that definitions and study populations must be clarified before specific biomarkers can be identified. (Bigras et al., International Journal of Audiology, 2023)
Hyperacusis is far more common in autism, and CBT-based approaches show early promise. Lifetime prevalence is estimated at up to 60% in autistic people versus 17.1% in those without autism; in a single case report, an 11-year-old autistic boy given modified CBT with exposure therapy had improved loudness discomfort levels on audiology testing. (Carson et al., Frontiers in Psychiatry, 2024)
A minimally invasive ear surgery has helped some people with severe hyperacusis. In a single-center prospective trial of 40 patients, 80% of those who had the newer window-reinforcement technique improved, compared with 60% with the original technique, and results held at a mean follow-up of 2 years. (Silverstein et al., American Journal of Otolaryngology, 2020)
What is hyperacusis?
Hyperacusis is a hearing disorder characterized by an increased sensitivity to sounds that most people perceive as normal. Individuals with this condition, also known as decreased sound tolerance (DST), often feel as though the volume of the world has been turned up to an intolerable level. [1] Common environmental sounds, such as the hum of a refrigerator, the rustle of a newspaper, or the sound of running water, can become overwhelming, painful, or even frightening.
This condition differs from typical hearing loss, though the two often coexist. While hearing loss involves a reduced ability to detect sounds, hyperacusis involves a failure in the brain's ability to regulate and process sound intensity. This sensory overload can lead to significant psychological distress, including irritability, anxiety, and a tendency to avoid social situations to escape potential noise triggers. [1]
What are the symptoms of hyperacusis?
The hallmark symptom of hyperacusis is the perception of regular sounds as uncomfortably loud or physically painful. The intensity of this discomfort can range from a mild annoyance to a severe reaction that may impact balance or, in rare cases, trigger seizures. Beyond the perceived loudness, individuals may experience physical sensations in the ears, such as a feeling of fullness or pressure, similar to the sensation felt during an airplane's ascent. [1]
The four types of sound sensitivity
Healthcare providers often categorize hyperacusis into four distinct types based on the predominant symptom experienced by the patient. These categories help clinicians tailor treatment strategies to the specific needs of the individual.
Type | Description |
Loudness | Normal volume sounds are perceived as uncomfortably loud. |
Annoyance (misophonia) | Specific noises trigger intense negative emotional reactions. |
Fear (phonophobia) | An intense fear of sounds and their potential impact. |
Pain | Extreme sensitivity that results in physical ear or head pain. |
What causes hyperacusis?
There is no single identified cause for hyperacusis, but several medical theories suggest it stems from neurological or structural issues. One leading theory involves damage to the auditory nerve, which transmits sound signals from the inner ear to the brain. Another possibility is dysfunction of the facial nerve, which controls the small muscle in the ear responsible for regulating sound intensity. [1]
Common risk factors and links
Hyperacusis is frequently associated with other medical conditions and environmental factors. It is particularly common among individuals who also suffer from tinnitus (ringing in the ears) or Williams syndrome. Additionally, nearly half of all people with hyperacusis also struggle with behavioral health conditions such as anxiety or depression. [1]
Noise exposure: Long-term exposure to loud environments (e.g., construction or music industry) or a single sudden loud event like a gunshot.
Medical conditions: Links have been found with autism, Bell's palsy, Lyme disease, Ménière's disease, and migraines.
Medications: Certain "ototoxic" drugs can damage hearing structures as a side effect, leading to increased sensitivity.
Trauma: Head injuries or complications from ear surgery can increase the risk of developing the disorder.
How is hyperacusis diagnosed?
Diagnosing hyperacusis typically requires a consultation with an ear, nose, and throat (ENT) specialist or an audiologist. The process begins with a thorough review of the patient's medical history and a physical examination of the ear structures. Specialists use specific tools to measure the degree of sensitivity and rule out other underlying conditions. [1]
Diagnostic tools
Test type | Purpose |
Loudness discomfort level (LDL) | Measures the exact decibel level at which sounds become uncomfortable. |
Questionnaires | Evaluates how noise sensitivity impacts daily life and mental health. |
Tympanometry | Checks the function and movement of the eardrum. |
Imaging and lab tests | MRI or blood work to check for facial nerve damage or infections like Lyme disease. |
How is hyperacusis managed and treated?
While there is currently no universal cure for hyperacusis, several therapeutic approaches can significantly reduce symptoms and improve quality of life. The goal of treatment is generally to retrain the brain's auditory processing system to tolerate sound more effectively.
Therapeutic approaches
Sound therapy: This involves gradual, safe exposure to increasing levels of sound to build tolerance over time. Most patients see improvement within six to twelve months of consistent therapy. [1]
Cognitive behavioral therapy (CBT): CBT helps patients manage the negative emotions and anxiety associated with loud noises, teaching effective coping mechanisms.
Tinnitus retraining therapy (TRT): Using "pink noise"—steady, calming sounds like rain or wind—to create a soothing auditory environment that makes jarring noises less impactful.
Surgery: In cases where the condition is caused by structural issues or facial nerve paralysis, surgical intervention may be used to support the inner ear bones.
Conclusion
Hyperacusis is a challenging condition that can turn the modern world into a painful environment. However, with professional guidance and the right combination of therapies, many people are able to retrain their auditory systems and regain their quality of life. It is crucial to seek medical help rather than relying on earplugs, which can inadvertently increase sensitivity over time.

Frequently Asked Questions
Can hyperacusis go away on its own?
In some cases, such as when it is a side effect of medication or post-surgery healing, it may resolve. However, for many, it is a long-term condition that requires active management.
Is hyperacusis the same as tinnitus?
No, but they often happen together. Tinnitus is hearing a sound that isn't there (like ringing), while hyperacusis is an over-sensitivity to sounds that are there.
Should I wear earplugs all the time to protect my ears?
No. Constant use of earplugs can make your brain even more sensitive to sound once you take them out. It is better to use them only in truly dangerously loud environments.
Can stress make hyperacusis worse?
Yes. Symptoms often flare up or feel more intense when you are stressed, tired, or anxious about noise exposure.
Is hyperacusis related to autism?
Hyperacusis can be. Sensory processing issues, including extreme sound sensitivity, are common in individuals on the autism spectrum.
What is "pink noise"?
Pink noise is a steady sound that contains all audible frequencies, but with more power at lower frequencies, making it sound like natural rain or wind.
How rare is hyperacusis?
Hyperacusis is not rare, though estimates vary widely because it is often underreported or misdiagnosed; one review cites lifetime rates of about 17% in people without autism and up to 60% in autistic people.
Can children have hyperacusis?
Yes, children can develop hyperacusis, particularly those with conditions like Williams syndrome or autism.
Does hyperacusis cause hearing loss?
Hyperacusis itself does not cause hearing loss, but the two conditions are often linked to the same underlying ear damage.
Can migraines trigger sound sensitivity?
Yes, phonophobia (fear or pain from sound) is a common symptom of migraine attacks.
What is an ototoxic medication?
Ototoxic medications are drugs that have the potential to damage the ear, leading to hearing loss, tinnitus, or balance issues.
How long does sound therapy take?
Most patients begin to notice a significant increase in their sound tolerance within 6 to 12 months of starting therapy.
Is there a specific diet for hyperacusis?
There is no evidence that a specific diet cures hyperacusis, though managing overall health and stress levels can help.
Can a head injury cause this?
Yes, trauma to the head or ear can damage the auditory system and lead to decreased sound tolerance.
Who treats hyperacusis?
You should see an otolaryngologist (ENT) or an audiologist who specializes in sound sensitivity disorders.
