Sound Sensitivity, Hyperacusis and Misophonia: When Everyday Sounds Become Overwhelming

The clatter of dishes. A running faucet. A conversation in the next room. The sound of someone chewing. For most of us, these sounds barely register. Our ears detect them, our brains decide they are not particularly important, and within seconds they fade into the background of everyday life. But for someone living with decreased sound tolerance, these same sounds can become impossible to ignore. They may seem unbearably loud, physically uncomfortable, painful, emotionally distressing, or even threatening.

As a neuroscientist and clinical audiologist, I think one of the biggest mistakes we make when talking about sound sensitivity is assuming that everyone who says, “Sounds bother me,” is describing the same problem. They are not. Hyperacusis, misophonia, noise sensitivity and phonophobia can certainly overlap, but they represent different patterns of how the auditory system and brain respond to sound. Understanding that distinction is important because treatment should never begin with a label or a device. It should begin with understanding exactly what the patient is experiencing.

What Do We Mean by “Sound Sensitivity”?

“Sound sensitivity” is really an umbrella term. In clinical practice, we often use the broader term decreased sound tolerance to describe several conditions in which a person has difficulty tolerating sounds that other people may barely notice. Importantly, the problem is not always that sounds are too loud. Sometimes the problem is a specific sound. Sometimes it is the emotional meaning attached to that sound. And sometimes it is the anticipation or fear of what exposure to sound might do.

A clinical tutorial published in the American Journal of Audiology provides a useful framework for distinguishing among these conditions. Hyperacusis generally refers to physical discomfort or pain associated with sounds at levels that most people can comfortably tolerate. Misophonia refers to an intense emotional and physiological reaction to particular trigger sounds, often regardless of their actual volume. Noise sensitivity describes a broader feeling of annoyance, discomfort or being overwhelmed by noisy environments, while phonophobia involves fear or anticipation that a sound may cause pain, discomfort or worsening of another condition. [1]

These distinctions are useful clinically, but I do not expect patients to walk into an office already knowing which category they fit into. That is our job. What I want patients to understand is that there are different reasons everyday sounds can become difficult to tolerate, and determining what is driving the reaction is an important part of determining what we should do about it.

What Is Hyperacusis?

Hyperacusis is probably the condition most people think of when they hear the term sound sensitivity. It is characterized by a reduced tolerance to the loudness of ordinary sounds. A vacuum cleaner, blender, running water, traffic, silverware hitting a plate or a group of people talking may suddenly seem much louder or more intense than it should. For some people, these sounds are simply uncomfortable. For others, they may cause pressure, headache, ear pain or a lingering worsening of symptoms even after the sound has stopped.

The American Speech-Language-Hearing Association describes hyperacusis as heightened sensitivity to ordinary environmental sounds that people without hyperacusis generally tolerate. [2] What is important to understand, however, is that hyperacusis is not simply “really good hearing,” nor is it someone being overly dramatic about noise. A person can have hyperacusis with hearing loss, with tinnitus or even with hearing thresholds that appear relatively normal on a standard audiogram.

That last point is especially important because the traditional hearing test tells us only a small part of the auditory story. An audiogram measures the quietest tones a person can detect in a highly controlled environment. It does not tell us everything about the health of the cochlea, auditory nerve or the brain’s ability to process and regulate sound. A patient can therefore have an audiogram that looks relatively good on paper while still experiencing very real auditory dysfunction in everyday life.

Hyperacusis has been associated with a number of conditions, including hearing loss, tinnitus, migraine, head injury and other medical or neurological disorders. Researchers are continuing to investigate the underlying mechanisms, and we do not yet have one explanation that accounts for every case. That uncertainty is precisely why I am hesitant whenever I hear someone make sweeping claims about “the cause” of hyperacusis. There probably is not one cause, just as there probably will never be one treatment that works for every patient.

Misophonia Is Different

Misophonia is often grouped together with hyperacusis, but the two should not be treated as interchangeable. With misophonia, the defining issue is typically not how loud a sound is. It is the particular sound itself, its pattern, its source or sometimes the meaning the brain has attached to it.

Chewing is perhaps the classic example, but other triggers can include lip smacking, sniffing, throat clearing, pen clicking, keyboard tapping and repetitive movement associated sounds. These sounds may produce an immediate and intense reaction that includes anger, disgust, anxiety, muscle tension, increased heart rate or an overwhelming urge to leave the situation. Importantly, the triggering sound can be extremely quiet. Someone with misophonia might comfortably listen to loud music and yet find the quiet sound of another person chewing almost unbearable.

An international panel of experts developed a consensus definition of misophonia in 2022 after reviewing the available scientific literature. They described it as decreased tolerance to specific sounds or stimuli associated with those sounds, capable of producing emotional, physiological and behavioral responses that are not typical for most people and that may interfere significantly with social, occupational or academic life. [3]

This is an important distinction because misophonia should not be dismissed as someone being irritable, difficult or “too sensitive.” At the same time, we should not simply call every negative reaction to sound hyperacusis. The underlying pattern matters because the treatment approach may be very different.

Hyperacusis Versus Misophonia: Understanding What Is Driving the Reaction

One of the simplest ways I explain the difference is to ask what characteristic of the sound is actually driving the reaction. In hyperacusis, intensity is generally central to the problem. Many different sounds may become uncomfortable once they reach a certain level. In misophonia, the identity or meaning of the sound is generally more important than its volume.

Think about a family dinner. Someone with hyperacusis may struggle because the room contains overlapping conversations, silverware, dishes and sudden bursts of laughter. The overall sound environment becomes uncomfortable or physically difficult to tolerate. Someone with misophonia may be perfectly comfortable with that overall noise level but experience an immediate and intense reaction to one person chewing across the table. Meanwhile, someone with phonophobia may begin feeling anxious before dinner even starts because they are afraid the noise will cause pain or worsen their tinnitus.

Of course, human beings rarely fit perfectly into textbook categories. A patient may have hyperacusis and tinnitus. Another may experience both hyperacusis and misophonia. Fear and avoidance may develop after repeated episodes of discomfort. This is why a good clinician should be listening for the pattern rather than trying to force a patient into a diagnostic box.

Why Can Completely Normal Sounds Suddenly Feel Too Loud?

This is where the neuroscience becomes particularly interesting. One of the leading models used to explain hyperacusis involves something called central gain. I often describe central gain as the brain’s internal volume control.

Our auditory system is constantly adjusting itself based on the information it receives from the ear. If input from the cochlea or auditory nerve becomes reduced or altered, the central auditory system may attempt to compensate by increasing neural activity. In very simple terms, when the brain believes it is receiving less auditory information, it may effectively “turn up the volume” in an attempt to recover some of what is missing.

The problem is that turning up the gain does not necessarily restore the quality of the original auditory signal. Instead, increased central gain may make neural responses to sound excessively strong. Sounds that should be perceived as moderate can begin to feel abnormally intense. This model has been studied extensively in relation to both tinnitus and hyperacusis. [4]

I sometimes compare it to turning up the gain on a microphone when the incoming signal is weak. You may make the desired signal louder, but you also amplify everything else. The system becomes increasingly sensitive, and information that should have remained in the background can suddenly become prominent.

It is important, however, not to turn central gain into another oversimplified explanation. It is a leading scientific model, not a proven universal mechanism for every person with hyperacusis. Research supports the idea that reduced or altered cochlear input can be associated with increased sound evoked neural activity higher in the auditory system, but scientists are still trying to understand why those changes produce tinnitus in one person, hyperacusis in another, both conditions in another and seemingly neither condition in someone else. [4]

What central gain does help illustrate is the larger point: the ear and brain operate as a system. Sound does not stop when it leaves the cochlea. Auditory information travels through complex neural pathways that interact with attention, memory, emotion and the body’s autonomic and threat response systems. The brain must constantly determine not only what a sound is, but whether it matters and whether it represents a potential threat. When those networks become dysregulated, the consequences can extend well beyond simply perceiving something as “too loud.”

Does Sound Sensitivity Become More Common as We Age?

Aging changes the auditory system. That should not be controversial. The sensory cells of the cochlea can become damaged over time, the auditory nerve can lose connections, and the central auditory pathways themselves undergo age related changes. Add decades of occupational noise, concerts, machinery, military service, recreational sound exposure, medications, illness and other health factors, and the auditory system arriving at age 70 is obviously not identical to the one we had at age 20.

That does not mean hyperacusis is an inevitable consequence of aging. It is not. Hyperacusis occurs across the lifespan, and the prevalence literature is surprisingly inconsistent. A 2023 systematic review discussed estimates in the range of approximately 9% to 15%, while other reviews have reported much broader general population estimates, from less than 1% to more than 17%. [5,6] Those enormous ranges tell us something important: researchers are not always defining or measuring the same phenomenon.

For me, the more clinically useful question is not whether someone fits a prevalence statistic. The important question is whether their tolerance of sound has changed and whether that change is beginning to affect their ability to participate in life.

When Sound Sensitivity Begins Changing Your Life

This is the part of sound sensitivity that can become particularly concerning. A person discovers that a restaurant is uncomfortable, so they stop going. Grocery stores become difficult, so they shop only during quiet hours. Family gatherings become exhausting, so they leave early. Eventually, they may begin declining invitations altogether because avoiding sound feels safer and easier than risking another bad experience.

What began as an auditory problem can therefore have much broader consequences. Persistent sound sensitivity can affect sleep, concentration, mood, relationships, work and social participation. Some patients describe being mentally exhausted at the end of the day because they have spent hours anticipating sounds, monitoring their environment and trying to control their reactions.

This does not mean hyperacusis “causes dementia,” nor do I think we should make claims the evidence cannot support. But as someone who has spent much of my career talking about hearing, cognition and healthy aging, I take social withdrawal and reduced engagement seriously. We know that maintaining social connection, physical activity and cognitive engagement matters as we age. A condition that progressively shrinks someone’s world deserves attention.

There are also situations in which sound sensitivity requires more immediate medical evaluation. Symptoms that begin suddenly, follow a head injury or significant noise exposure, affect one ear much more than the other, or occur alongside sudden hearing loss, severe dizziness, facial weakness, drainage, significant ear pain or other neurological symptoms should not simply be assumed to be hyperacusis. Those symptoms may require medical evaluation beyond a routine hearing visit.

How Do We Evaluate Hyperacusis and Misophonia?

There is no single test that can look at a patient and announce, “You have hyperacusis.” There is no blood test, brain scan or questionnaire that can completely characterize every decreased sound tolerance condition. A proper evaluation therefore begins with something surprisingly simple: listening to the patient.

I want to know which sounds cause the problem, what those sounds feel like, how quickly the reaction occurs and what happens afterward. Is the primary response discomfort or actual pain? Is it anger, disgust, fear or panic? Does the problem occur once sounds reach a certain intensity, or is it tied to one particular trigger? How long does the reaction last? Did symptoms begin after an illness, noise exposure, medication change, head injury or noticeable hearing change? Are tinnitus, migraine, dizziness, difficulty hearing in noise, anxiety or sleep problems also present? Most importantly, how is this affecting the person’s life?

A comprehensive audiological evaluation may include examination of the ear, measurement of hearing thresholds, speech testing and additional measures selected according to the patient’s symptoms and history. Questionnaires can also be useful because they help us quantify the functional impact of the condition and establish a baseline that can later be used to measure progress. Loudness discomfort testing may sometimes be appropriate, although it must be performed thoughtfully and cautiously because protocols vary and some patients find this type of testing difficult. [2]

Depending on the clinical picture, appropriate care may also involve an otolaryngologist, neurologist, psychologist, psychiatrist, primary care clinician or occupational therapist. That is not passing the patient from provider to provider. It is recognizing that sound tolerance can involve multiple systems and that good healthcare sometimes requires multiple disciplines.

The purpose of the evaluation is not to prove that sounds bother someone. I believe the patient when they tell me that. The purpose is to understand why they are having that experience, determine whether another medical condition requires attention and develop a treatment strategy around what they actually want to be able to do again.

Can Hyperacusis Be Treated?

Yes, hyperacusis can be managed, and many patients can improve. But this is another area where I think we have to resist the temptation to promise a single miracle treatment. Hyperacusis is heterogeneous, our understanding of its mechanisms is still evolving, and treatment should be individualized to the person sitting in front of us.

Depending on the findings, treatment may involve education and counseling, treatment of coexisting hearing loss or tinnitus, carefully controlled sound enrichment, cognitive behavioral therapy and coordination with other healthcare professionals. The objective is not simply to make sounds louder until the patient “gets used to them.” The goal is to help the auditory system and brain develop a healthier relationship with everyday sound while reducing the distress, fear and avoidance that may have developed around it.

Sound therapy is one commonly used component of treatment. This may involve environmental sounds, music, broadband noise, ear level sound generators or, when clinically appropriate, carefully programmed hearing technology. The principle is generally to introduce safe and tolerable sound in a controlled way rather than forcing someone to endure painful exposure. A 2024 scoping review of sound therapy for hyperacusis found considerable variation in the devices, protocols and outcome measures being used and concluded that stronger clinical trials and clearer guidance are still needed. [6] In other words, sound therapy may be helpful, but anyone claiming to have one standardized sound protocol that works for everybody is getting ahead of the science.

Cognitive behavioral therapy, or CBT, can also play an important role for some patients. Unfortunately, the moment you mention CBT, some people hear, “The doctor thinks this is psychological.” That is not what CBT means. CBT is used throughout healthcare to help patients change the distress, threat response and avoidance behaviors that can develop around very real symptoms. In a randomized controlled trial of 60 patients with hyperacusis, CBT produced improvement across several measures compared with a waiting list group, with many of those gains maintained at 12 months. [7] That does not make CBT a cure for every case of hyperacusis, but it makes it a legitimate treatment option worth considering.

For patients who also have hearing loss or tinnitus, appropriately fitted prescription hearing technology may be another component of care. Notice that I said component. A hearing aid is a tool, not the treatment plan. If hearing technology is used, programming needs to respect the patient’s reduced sound tolerance, output needs to be carefully controlled and verified, and the technology needs to fit within a broader rehabilitation strategy. Simply putting amplification on someone’s ears and making the world louder is obviously not a thoughtful treatment for sound intolerance.

What About Hearing Protection?

This is another area where good intentions can occasionally create problems. If a sound is genuinely hazardous, protect your hearing. I have spent enough of my career studying the auditory system to be very clear about that. Hearing protection around dangerous noise is appropriate and important.

But wearing strong hearing protection all day in ordinary, safe environments is a very different issue. Excessive protection can increase the contrast between silence and normal environmental sound, contribute to isolation and reinforce the belief that everyday sound is dangerous. ASHA therefore recommends hearing protection for excessive noise while generally discouraging routine protection from safe everyday sounds. [2]

There are important exceptions, particularly for people experiencing severe pain based hyperacusis or significant sound reactivity, which is why I would never tell every patient to simply “take the earplugs out.” Treatment needs to be individualized. The larger goal is to protect the auditory system from genuinely dangerous sound without teaching the brain that ordinary life itself requires protection.

Can Misophonia Be Treated?

The research on misophonia is younger than the research on hyperacusis, so we need to be appropriately cautious about what we promise. There is currently no single treatment that works for everyone. Management may involve education, psychological care, environmental modifications, family counseling and strategies designed to reduce the intensity of the response while helping the person participate more fully in everyday life.

CBT currently has some of the strongest controlled evidence. In the first randomized clinical trial of CBT for misophonia, 54 adults were included and 46 completed treatment. Group CBT significantly reduced symptoms compared with a waiting list condition, with 37% of the treatment group demonstrating clinical improvement compared with none of the waiting list group. Benefits were also maintained at one year follow up. [8]

That is encouraging, but it is one trial, not proof of a universal cure. The science of misophonia is developing rapidly, and our treatment recommendations should develop with it.

One thing I do feel strongly about is that the solution should not be to blame the person making the triggering sound, nor should we tell the person experiencing misophonia to simply “get over it.” Neither approach is particularly useful. The goal is to reduce suffering, increase flexibility and help people remain connected to the people and activities that matter to them.

What Can You Do Right Now?

If you are experiencing sound sensitivity, you do not need to diagnose yourself before asking for help. In fact, I would rather you did not. Start by paying attention to the pattern. Keep track of which sounds bother you, whether the reaction is related to loudness or a specific trigger, what the reaction feels like and how long it lasts. Make note of any tinnitus, changes in hearing, dizziness, migraine, medication changes, recent illness, significant noise exposure or head injury. Those details can be extremely useful during a clinical evaluation.

In the meantime, use hearing protection when sound is genuinely hazardous, but be cautious about progressively withdrawing from safe everyday sound unless a clinician has recommended that strategy for your specific condition. If comfortable background sound is tolerable, maintaining some normal sound in your environment may be preferable to seeking complete silence. Sleep, stress and overall health also matter because the auditory system does not operate independently from the rest of the nervous system.

Most importantly, pay attention to what the condition is taking away from you. Are you skipping dinners with friends? Avoiding your grandchildren? No longer going to restaurants? Turning down invitations because you do not know how loud the environment will be? Those changes matter. The goal of treatment is not merely to improve a number on a questionnaire. It is to help you participate in your life again.

A Better Way Forward

Hyperacusis, misophonia and other forms of decreased sound tolerance are perfect examples of why modern hearing healthcare has to move beyond thinking about the ear as an isolated organ. Hearing is an ear to brain process, and our response to sound reflects an extraordinarily complex interaction among the cochlea, auditory nerve, central auditory pathways, attention, memory, emotion and autonomic nervous system. When that system changes, everyday sounds can become uncomfortable, distressing or even painful.

The encouraging news is that there are ways to help. The first step is not buying a device, living in earplugs or searching the internet for a miracle cure. It is understanding what type of sound intolerance you are experiencing, identifying potential auditory and medical contributors and developing an individualized treatment plan that helps you gradually regain comfort, confidence and participation.

At Hearing & Brain Centers of America, that is how we approach these conditions. If everyday sounds have become painfully loud, specific sounds trigger an intense reaction, or fear of sound is beginning to change how you live your life, schedule a comprehensive evaluation. Our goal is not simply to give you another diagnosis. Our goal is to understand what has changed within your auditory system, determine how those changes are affecting your brain and your daily life, and build a treatment plan designed to help you reconnect with the world around you.

Frequently Asked Questions

Why am I suddenly sensitive to sound?

There are many potential reasons that sound tolerance can change. Symptoms may appear following significant noise exposure, changes in hearing, head injury, migraine, illness or other changes affecting the auditory or nervous system. In some patients, however, there is no single obvious event that explains the onset. Sudden sound sensitivity accompanied by sudden hearing loss, severe dizziness, facial weakness or other neurological changes deserves prompt medical evaluation rather than simply assuming the problem is hyperacusis.

Is hyperacusis the same thing as having sensitive hearing?

Not exactly. Hyperacusis is not simply the ability to hear very quiet sounds. It involves reduced tolerance to sounds that most people can comfortably tolerate. Someone can actually have measurable hearing loss and hyperacusis at the same time because hearing sensitivity and sound tolerance are not the same thing.

Is misophonia a type of hyperacusis?

They are generally considered distinct conditions, although a person can experience both. Hyperacusis is typically related to the intensity of sound, whereas misophonia is associated with particular sound patterns or triggers and may occur even when those sounds are very quiet. Understanding which pattern is present is one reason a detailed clinical history is so important.

Can I have hyperacusis even if my hearing test is normal?

Yes. A standard audiogram measures the quietest tones you can detect across a limited range of frequencies. It does not measure every aspect of cochlear health, auditory nerve function, central auditory processing or sound tolerance. This is one reason I have long argued that we should stop treating the audiogram as if it tells us everything there is to know about someone’s hearing. It does not.

Should I wear earplugs all day if I have hyperacusis?

Generally, no. Hearing protection absolutely has a place when sound levels are hazardous. But routinely wearing strong hearing protection in safe environments may reinforce sound avoidance and potentially contribute to greater sensitivity in some individuals. Patients experiencing severe pain or significant reactivity need individualized recommendations, so this is something that should be discussed with a clinician familiar with decreased sound tolerance.

What kind of doctor treats sound sensitivity?

I would begin with an audiologist who has experience evaluating tinnitus, hyperacusis and other forms of decreased sound tolerance. Depending on your history and symptoms, treatment may also involve an otolaryngologist, neurologist, psychologist, psychiatrist, primary care clinician or occupational therapist. Good care is not about one profession owning the problem. It is about assembling the right expertise for the individual patient.

Can hearing aids help hyperacusis?

They can be helpful for selected patients, particularly when hyperacusis occurs alongside hearing loss or tinnitus, but hearing aids are not a universal treatment for sound sensitivity. When amplification is appropriate, output and programming must be individualized, carefully controlled and verified. The hearing aid should be viewed as one tool within a comprehensive treatment plan rather than the treatment itself.

Does using CBT mean my symptoms are psychological?

No. CBT is used for many medical conditions involving very real physical symptoms. In hyperacusis and misophonia, it may help reduce the fear, distress, avoidance and threat responses that can develop around sound. That does not mean the auditory symptoms are imaginary. It means we are treating the entire person rather than pretending the auditory system exists separately from the rest of the brain.
