Their reactions included an increased heartrate and sweaty palms. The individuals with misophonia also displayed signs of physical stress when exposed to the trigger sounds. Participants responded to the neutral and negative sounds in the same ways, but those with misophonia rated the eating and breathing sounds as “highly disturbing” while those in the control group did not. Each group was asked to rate the unpleasantness of a variety of different sounds, including common triggers such as eating and breathing, universally-disparaged negative sounds like the aforementioned nails on a chalkboard and neutral sounds such as footsteps or chirping birds. Their results, published in Current Biology in 2017, indicate that the brains of people with misophonia appear to respond differently to certain sounds. Researchers from the University of Iowa examined 20 adults with the disorder and 22 without. Patients were often diagnosed with mood disorders, especially when they displayed anxiety or depression – emotions that often accompany misophonia.Ī recent study, while small in scale, offers some insight into the mechanisms that trigger misophonia. Sometimes, small repetitive motions – somebody fidgets, wriggles a foot or accidentally brushes against you – are enough to provoke an exaggerated response.ĭoctors aren’t sure what causes misophonia, and up until a few years ago, it didn’t even have a name. The disorder is sometimes referred to as selective sound sensitivity syndrome and is thought to be a survival mechanism employed by the brain in response to a perceived threat.Ĭommon misophonia triggers include oral sounds such as chewing, throat clearing, coughing and nose blowing finger or keyboard tapping clicking a pen humming and even breathing. It can generate intense emotional or physiological reactions such as fear, rage or panic. Misophonia is a disorder that causes an aversion to common sounds. The name for this condition is misophonia, and it can impact many facets of your daily life – but help is available. An estimated 15 percent of adults are extremely bothered by everyday noises that most people don’t even give a second thought. Hearing disorders take many different forms. We will together guide your treatment and counsel you about the solutions available.

We will complete a full audiologic evaluation, including a hearing test, and take a record of your medical history to accurately diagnose your condition and determine your Loudness Discomfort Levels (LDL). If you suspect you may have hyperacusis, let’s start with an evaluation and consultation. This treatment may take six months to a year, and maybe even longer for certain patients. This result is most obvious immediately after removing the ear protection.Īn effective treatment option is called sound desensitization, wherein a specialist works with you by exposing you to white noise at initially a very low volume, increasing it over time to improve tolerance. While this may help in the short term, it actually decreases the already poor tolerance of noise, increasing sensitivity in the long run. Some suffering from hyperacusis might seek relief by wearing earplugs or earmuffs. Identifying the underlying cause is always the first step in treating hyperacusis.
Hyperacusis is also linked with neurologic conditions such as PTSD, epilepsy, depression, migraines, cerebral palsy and autism.įor those whose hyperacusis is the result of trauma to the head or hearing system, symptoms may go away as the injury heals. Hyperacusis can be caused by a number of diseases including Bell’s palsy, Lyme disease, Meniere’s disease, head injury, temporomandibular joint (TMJ) syndrome and noise induced hearing loss. It is extremely uncommon for someone to be born with hyperacusis. Untreated hyperacusis can cause social isolation, phonophobia (fear of sounds), depression and more. Hyperacusis can affect people of any age, and it can occur in one or both ears. This number is higher among tinnitus sufferers, however, affecting about one in 1,000. Hyperacusis is rare, affecting only one in 50,000 people. For some, the sensitivity is only to certain frequencies or pitches. A person suffering from hyperacusis may find sounds like a running dishwasher, a nearby conversation or even the shuffling of papers unpleasantly loud or even painful. Hyperacusis is a heightened sensitivity to everyday sounds that most people can tolerate easily.
