  Hyperacusis is a heightened sensitivity to everyday sounds, often causing discomfort or pain. While the exact cause isn’t always known, hyperacusis can be linked to exposure to loud noises, head injuries, or certain neurological conditions. Some individuals develop hyperacusis after exposure to a sudden loud sound or over time from prolonged exposure to high noise levels. In other cases, conditions like migraine, autism, or anxiety disorders may contribute to sound sensitivity. […] Increased sound sensitivity can also be associated with changes in the inner ear or auditory pathways in the brain, where sound is processed. For individuals with hyperacusis, normal sounds may feel overwhelmingly loud or uncomfortable.

  Hyperacusis (hyper-ack-YOU-sis) an abnormal sensitivity to sounds. It is not a disorder or disease – it is a symptom of an underlying condition. People with hyperacusis perceive certain everyday sounds as annoying, uncomfortable, painful, distressing, and even terrifying. Hyperacusis can have a significant negative impact on activities of daily living. It can start gradually, or the onset can be sudden. Hyperacusis is also called decreased sound tolerance or sound sensitivity. […] The mechanisms that provoke sound sensitivity are unclear. One theory is abnormally increased sensitivity within the brain’s hearing system (increased auditory gain). If the brain were imagined as having a volume control dial, with hyperacusis the dial would be turned all the way up. Sounds that normally would be tolerated are perceived as too loud.

  Hyperacusis can be caused by different things, but doctors aren’t always sure of the exact cause. For example, experts are still figuring out why certain noises are uncomfortably loud for some kids. It may be due to how the brain handles sounds. Normally, your brain helps you know how loud or soft a noise is. With hyperacusis, the brain seems to confuse sounds and make them seem louder than they really are. […] Other causes are due to infections of the ear like a certain type of middle ear infection or of the nerves in the face, as with Bells palsy. Other possible causes include damage to the ear from a sudden loud noise (like a gunshot or fireworks), being around loud sounds for a long time, or taking certain medicines or poisons.

Some patients say they developed hypersensitivity to sound over a period. Others may come down with hyperacusis suddenly by attending a rock concert, firing a gun, air bag deployment in their car, fireworks, or any extremely loud sound. […] Other causes may include job related noise exposure, drugs, Lymes disease, Menieres, Temporomandibular Joint Syndrome (TMJ), head injury, Superior Canal Dehiscence Syndrome (SCDS), postoperative surgery, autism, or Down Syndrome. […] The appearance of hyperacusis in some of these disorders may provide clues as to the cause of hyperacusis. […] The protective mechanisms a normal ear employs to minimize the harmful effects of loud noise are malfunctioning, so noise may seem too loud even with hearing protection. There is some speculation that the efferent portion of the auditory nerve has been affected efferent meaning fibers that originate in the brain, which serve to regulate incoming sounds. This theory about hyperacusis suggests that the efferent fibers of the auditory nerve are selectively damaged while the hair cells that allow us to hear pure tones in an audiometric evaluation remain intact.

  Hyperacusis is a hearing condition that causes a heightened sensitivity to sound, making everyday noises, like running water, seem extremely loud. […] About 8 to 15 percent of adults have hyperacusis. This condition often affects people who have tinnitus, or ringing in the ears. […] Hyperacusis primarily affects people who have tinnitus, are assigned male at birth, and are older. […] Possible causes of hyperacusis include: High noise exposure. Loud noise is a major cause of hyperacusis. Exposure can happen over time (like playing loud music for many years) or a single occurrence (like hearing a gunshot). […] Head injury. An injury involving the head, jaw, or ear can lead to hyperacusis. One example is getting hit with an airbag in a car. […] Viral infections.

  Currently, there is no medical consensus on what exactly causes hyperacusis. […] In fact, around 50 percent of people living with tinnitus also go on to develop sensitivity to noise. […] Others have linked cases of the condition to autism and birth defects, which may be the cause in a small number of individuals. […] However, auditory experts generally caution against ascribing a single cause. […] For instance, it could also be due to the side effects of an auto-immune disorder, ear infections, and traumatic acoustic events like the sound of a gun blast. […] However, medical data suggests that the most common primary cause is physical trauma. […] Any shock to the nervous system could lead to the condition, such as whiplash in an automobile accident or even a sports injury. […] Hyperacusis is a serious auditory problem and, though a cure may not be available, there are therapeutic options that can alleviate its symptoms.

  About 40% of people with tinnitus also experience hyperacusis, or sound sensitivity. […] Each year researchers add to a growing body of knowledge about the mechanisms and causes of hyperacusis. […] Acoustic trauma (exposure to very loud sound) can lead to the development of hyperacusis. […] Certain disorders are associated with sound sensitivities such as Lyme disease, Williams syndrome and Addisons disease to name a few. […] Hyperacusis can also develop in the absence of a definite cause and is not always associated with hearing loss or ear damage. […] Central auditory system hyperactivity is thought to contribute in most cases of tinnitus, loudness hyperacusis and even ear pain symptoms. […] Many researchers agree pain sensations are triggered as a result of dysfunction in the central auditory system. […] This is also known as neural pain, meaning it is being generated in the brain, rather than due to actual structural damage to the ear itself.

  Some have said that it involves a direct malfunction of the facial nerve; as a result, the stapedius muscle is unable to dampen sound. […] Since an estimated 10% of all tinnitus patients have no measurable hearing impairment; it comes as no surprise that other ear pathologies including hyperacusis can occur in the absence of hearing loss. Others feel hyperacusis is purely a central processing problem limited to how the brain perceives sound. Hyperacusis is not uncommon. It has been said that 5 million patients have tinnitus and 40% of those patients have hearing sensitivity or hyperacusis. […] Some dominant voices in the world of tinnitus have said that tinnitus and hyperacusis are two sides of the same coin. If a cure is found for one, it is likely that a cure will be found for the other. In the meantime, hyperacusis is a mystery but clues are beginning to surface which are very encouraging and hopeful.
