Are you wondering why you're sensitive to sound? You're not alone. Around 20 to 40 percent of people are noise-sensitive, and it can be caused by various factors. One cause could be hyperacusis, a rare hearing disorder where everyday sounds are amplified and can cause pain or discomfort. This condition arises from the way the brain's central auditory processing centre perceives noise. Migraines, which are also associated with sensitivity to sound, are the leading cause of hyperacusis. Another cause of sound sensitivity could be anxiety or stress, which can heighten your nervous system's reactivity, making you more prone to being startled by loud or triggering noises. Additionally, as we age, our auditory system can over-recruit, amplifying unwanted noise. If you're struggling with sound sensitivity, treatments like sound desensitization and cognitive-behavioural therapy can help.

What You'll Learn
Hyperacusis, a rare hearing disorder
Hyperacusis is a rare hearing disorder that affects around 1 in 50,000 people. It is characterised by an increased perception of the loudness of sounds, often accompanied by pain and annoyance, which can lead to fear and anxiety. People with hyperacusis may find everyday sounds unbearably loud, such as people chatting, a car engine running, or water running in a sink. The condition can take a toll on mental health and social life, with sufferers often avoiding social situations to reduce the risk of encountering loud noises.
The exact causes of hyperacusis are not yet fully understood, but it is believed to be related to the way the brain processes and perceives sound. It is thought that damage to the auditory nerve or the facial nerve may play a role in the development of the condition. Hyperacusis is also often associated with other conditions, such as tinnitus, Bell's palsy, Ramsay Hunt syndrome, and Lyme disease.
The symptoms of hyperacusis can vary in severity and duration. Some people may experience short-term hyperacusis, lasting from weeks to less than a year, while others may have long-term hyperacusis, which can span years and even become permanent. It is important to note that hyperacusis is not the same as "recruitment," which is a disorder associated with hearing loss and abnormal perception of sound at higher volumes.
There are several treatment options available for hyperacusis, including sound desensitisation techniques, behavioural counselling, and acoustic therapy. Sound desensitisation involves gradually exposing the patient to increasing levels of sound in a controlled manner, helping them to build tolerance over time. Counselling helps patients manage the anxieties and fears associated with the condition, while acoustic therapy aims to reduce sensitivity to sounds and promote a positive perception of sound.
While there is no cure for hyperacusis at present, these therapies can significantly improve quality of life by reducing the negative impact of the condition on mental health and social functioning.

Migraines and sensitivity to sound
Sound sensitivity, or hyperacusis, is a hearing disorder that makes it difficult to tolerate everyday sounds. It is characterised by certain sounds seeming unbearably loud, even though people around may not notice them. Hyperacusis can lead to pain, discomfort, and even severe symptoms like seizures. It is often associated with tinnitus, a buzzing or ringing in the ears. The condition arises from the way the brain's central auditory processing centre perceives noise, with the brain confusing or exaggerating certain vibrations.
Now, onto the connection between migraines and sound sensitivity. Migraines are intense, throbbing headaches that usually affect one side of the head. They are the world's most common neurological disorder, affecting 8.4% of people even in countries with a relatively low prevalence. Migraines are often accompanied by hypersensitivity to lights, smells, and sounds, with 70-80% of migraine patients experiencing sound hypersensitivity. This heightened sensitivity can make everyday sounds seem unbearably loud, and some people with migraines even report sound as a trigger for their migraine attacks.
The exact reasons for this comorbidity are not yet fully understood. However, researchers believe that increased sensitivity to sound and light may be symptoms of a migraine before the head pain begins. Some studies have found that migraine patients rate certain everyday sounds, such as ambulance, police car, and railroad crossing bell noises, as significantly more unpleasant than healthy individuals. These sounds tend to have a lower amplitude and lack temporal variation in the 400-Hz band, which the human ear is highly sensitive to.
Managing migraine sound sensitivity can be challenging, but there are some strategies that may help. White noise apps can be useful in masking annoying background noises and reducing sensory stimuli. Noise-cancelling headphones can also be a discreet way to protect yourself from painful noise in public spaces. Additionally, certain vehicles, restaurants, and hotels may offer more noise reduction than others, although these options tend to be more expensive.
If you are experiencing sound sensitivity, it is important to consult a healthcare professional for a proper diagnosis and treatment plan.

Anxiety and sound sensitivity
Sound sensitivity, or hyperacusis, is a hearing disorder that makes it difficult to tolerate everyday sounds. It is characterised by certain sounds seeming unbearably loud, even though people around may not notice them. Hyperacusis is rare, affecting 1 in 50,000 people, and can cause pain and discomfort. It is often accompanied by tinnitus, which is a buzzing or ringing in the ears.
Anxiety can cause sound sensitivity, and hypersensitivity or "oversensitivity" is a common symptom of anxiety. When anxious, the body is on high alert, and the greater the anxiety, the higher the natural baseline for stress. This can lead to an increased sensitivity to sound, with loud or triggering noises causing a rush of negative emotions. This is known as auditory hypersensitivity and can cause distress. Sounds that trigger hypersensitivity are often related to past traumas or recurring causes of anxiety.
Exposure to triggering sounds can lead to adverse physical symptoms such as tension headaches or nausea. These symptoms may be exacerbated by certain sounds or increase the feeling of unease associated with anxiety attacks. In some cases, anxiety can cause people to perceive noises as louder than they are.
Cognitive behavioural therapy, particularly exposure therapy, can be effective in treating sound sensitivity related to anxiety. Exposure therapy involves gradually exposing oneself to triggering sounds in a safe and controlled setting, helping to reduce the anxious reaction over time. Relaxation techniques, such as meditation or deep breathing, can also help manage anxiety and sound sensitivity.
It is important to note that sound sensitivity can also be a symptom of misophonia, a condition where specific trigger noises cause strong emotions, body changes, or reactive behaviours. Misophonia is distinct from anxiety, but the two can co-occur.

Sound desensitisation treatments
There are several reasons why someone might be sensitive to sound. Hyperacusis is a rare hearing disorder that makes it hard to deal with everyday sounds. People with hyperacusis might experience certain sounds as unbearably loud, even though people around them might not notice these sounds at all. Hyperacusis can sometimes be painful and affect one's balance. It can be caused by another condition, such as migraines or Lyme disease, and in such cases treating the condition may stop hyperacusis. Misophonia is another condition that involves a decreased tolerance for specific sounds and things associated with them. Certain sounds can trigger strong emotions, body changes, or reactive behaviours. While it is not yet recognized as a distinct disorder, experts do recognize it and treatments are available. Some people with anxiety or PTSD might also experience hypersensitivity to sound.
Sound Desensitization
Sound desensitization involves working with a specialist to learn to deal with sound. One starts by listening to very quiet noises for a certain period every day and gradually builds up exposure to louder sounds. This therapy can take 6 months to a year or more to yield full benefits.
Cognitive Behavioural Therapy (CBT)
CBT has proven to be extremely helpful for individuals with anxiety symptoms. Exposure techniques, in particular, may be useful for reducing hypersensitivity.
Exposure Therapy
This involves gradually exposing oneself to a trigger in a safe and controlled setting. Over time, one's anxious reaction should decline and eventually be eliminated.
Relaxation Techniques
Relaxation techniques such as meditation or deep breathing can be used in conjunction with exposure therapy to calm anxiety symptoms and make them easier to tolerate.
Noise-Cancelling Devices
Noise-cancelling devices such as earplugs or headphones can be used to manage sound sensitivity by focusing the brain's hearing processes on something other than a trigger sound.

Sound sensitivity and autism
Sound sensitivity, or hyperacusis, is a common trait observed in individuals with autism. Hyperacusis is a hearing disorder that makes it difficult to tolerate everyday sounds. Individuals with autism often experience an exaggerated reaction to auditory stimuli, with sounds that may be considered normal by neurotypical individuals perceived as overwhelming by those with sound sensitivity.
According to a study published in the Journal of Autism and Developmental Disorders, up to 70% of individuals with autism experience sound sensitivity, compared to 8% of the general population. The prevalence of sound sensitivity within the autism spectrum disorder (ASD) population varies across studies, with rates of 37%, 18%, and 69% reported in different age groups and diagnostic categories. This variation may be due to differences in study samples, methodologies, and diagnostic criteria.
The exact cause of sound sensitivity in autism is not yet fully understood, but research suggests it may be related to neurological differences in the brain, specifically in the way the auditory system processes sounds. The processing of sensory information in individuals with autism differs from neurotypical individuals, leading to difficulties in filtering out irrelevant stimuli and heightened sensitivity to certain sounds. Studies have shown that certain brain regions, such as the amygdala and sensory processing cortices, exhibit increased activity in children with autism when exposed to sounds.
Signs and symptoms of sound sensitivity in individuals with autism can include a reluctance to visit noisy places, keen attention to detail and noises, agitation around low, droning sounds, and being easily startled. It is important to recognize and accommodate the specific needs of individuals with sound sensitivity to create environments that promote comfort and well-being. Strategies such as sound desensitization and auditory integration therapy (AIT) can be used to help manage sound sensitivity in individuals with autism.
Understanding the causes and mechanisms behind sound sensitivity in autism is crucial for developing effective support strategies. By recognizing the unique sensory challenges faced by individuals with autism, we can work towards creating inclusive environments that cater to their specific needs.
