Introduction:
Hyperacusis is a poorly understood rare auditory disorder. Until extremely recently hyperacusis was thought to be a psychosomatic condition, however, new research findings are uncovering that hyperacusis is actually an otological and neurological condition. Unfortunately, hyperacusis currently has no cure.
Currently most doctors treat hyperacusis using some combination of TRT, desensitization, cognitive-behavioral therapy, and counseling. Unfortunately, these treatments are not always affective in hyperacusis patients and in some cases have made their condition worse. Hyperacusis Research Is a nonprofit organization dedicated to ending noise induced pain. “Hyperacusis Research is committed to finding a cure for patients whose conditions have not significantly improved by current treatment options.”
Mechanisms:
Hyperacusis mechanisms are currently not well understood. Doctors and scientists do not yet a functional model of the auditory system. Currently, the suspected theoretical mechanisms for hyperacusis are as follows.
•1. Eighth auditory nerve
2. Auditory pain fiber nerve cells
3. Auditory cortex
4. Somatosensory cortex
5. Staples’ bone
6. Hair cells in cochlear
Doctors and scientists are still doing more research into the possible mechanisms of hyperacusis.
Hyperacusis setbacks:
Hyperacusis setbacks are currently a seriously overlooked aspect of hyperacusis. As mentioned in the above section the current treatment options have worsened some patient’s hyperacusis due to the exposure aspect of these therapies. Many patients also report experiencing setbacks from normal daily activities or environmental sounds.
A hyperacusis setback is when a patients pain level is elevated, and their tolerance decreased following exposure to sounds above their tolerance threshold. More research needs to be done to help doctors and patients better understand how they can prevent setbacks. Noise levels do not have to be extreme or even above average in order to produce a setback for a person with hyperacusis.
In a survey conducted “A clinically focused question asked: “If you have had a clinical evaluation for your hyperacusis, did the clinician ask you any question related to setbacks?”
Only 29 percent reported that the topic of setbacks was covered by their clinician.” In the hyperacusis, Sanford Cords study also demonstrates that setbacks are more prominent in hyperacusis patients then previously suspected, see the data below.

62% answered ‘every day’ or ‘continuously’ (see Figure 2). Of these, 75% indicated the pain was a direct result of being around a new loud noise. Most sufferers feel the pain immediately. When asked, ‘how long does the pain last?’, respondents indicated the following: 22% – five to 24 hours; 22% – several days; and 11% – several weeks or months.
When asked, ‘how often does the participant have a setback that makes their condition worse?’, 36% indicated at least weekly and only 25% responded with rarely or never. This setback makes the sufferer’s condition ‘moderately worse’ for 50% and ‘worse than it ever was’ for 23%. Figure 3 shows the results for the question, ‘how long does it take for the participant to recover from a setback?” Recovery takes days for 59% and weeks for 24%. Recovery is also proportional to the loudness and/or duration of the impacting noise.
“ These results represent critical components that need to be comprehended in clinical evaluations. A patient’s history of setbacks should be considered when determining the best treatment approach and expected outcome. Many patients will likely rank setback prevention and reduction of pain symptoms as their top priorities.”
Although many doctors are concerned that over protection will worsen patient’s hyperacusis condition, it seems that patients are more likely to suffer from setbacks due to exposure.
A New direction in Research:
Many patients with hyperacusis have to isolate themselves in quiet in environments. Many hyperacusis patients are unable to attend malls, restaurants, or other social activities. Patients with severe hyperacusis even have a hard time doing normal household activities.
Hyperacusis Research is not only researching a cure for hyperacusis, but is also looking into management options until a cure can be found. Hyperacusis Research has a section called “quiet your world.” Hyperacusis Research has several articles on: quiet products, suggested noise reduction strategies, and hearing protection.
The importance of sound avoidance and noise management is reinforced by the above section (hyperacusis setbacks). New treatments are also being invented to help hyperacusis patients. Hyperacusis Research just received a grant from the NIH to develop a hyperacusis device.
The hyperacusis device was developed by Dr. Craig Formby and Dr. David Eddins in collaboration with Bryan Pollard the President of Hyperacusis Research. The new hyperacusis device allows the patients complete control over the sound level that they hear. “For example, the sound level to dampen loud sounds will be customized to a patient’s Loudness Discomfort Levels.” A clinical trial is currently underway to evaluate the effectiveness of this device.
Dr. Herbert Silverstein has also recently invented a surgery for hyperacusis called Round and Oval Window Reinforcement Surgery. The surgery is designed to reinforce the round and oval window with skin tissue, this in turn reduces the sound vibrations in the ear, making sounds less painfully loud for patients.
A study was conducted on adult patients with severe hyperacusis to evaluate the effectiveness of this surgery. The surgery had a positive impact on many of the subject’s hyperacusis severity. “The results suggest that reinforcement of the round and oval window with temporalis fascia or tragal perichondrium may offer a significant benefit for individuals with severe hyperacusis that has not responded to traditional therapy.
ULL scores and self-report measures postoperatively demonstrate improved noise tolerance, high patient satisfaction, and enhanced quality of life.” Not everyone agrees with the direction of this new research. Not everyone in the medical community favors the procedure.
Dan Malcore, the publisher of the Hyperacusis Network, called the procedure “a Band-aid approach” and said that it did not address “the path to recovering decreased sound tolerance by re-establishing one’s tolerance to sound.”
Instead, Malcore pointed to tinnitus retraining therapy as proper protocol and treatment for hyperacusis. Almost half of the patients with hyperacusis also have tinnitus, the perception of ringing in your ears. Silverstein disagrees.
“Most new developments are met with a negative response at first,” said Silverstein. “Change is difficult, and it isn’t until there are years of proven reliance that the medical community turns around.”
The same statement can be made about the new approach in setback prevention, pain reduction, and the new hyperacusis device.
Hyperacusis and the ADA:
Due to its previous categorization as a psychosomatic condition until recently, hyperacusis was not recognized under the ADA. Bryan Pollard the president of Hyperacusis Research in collaboration with other people has worked very hard to change this. There is now a small section in the ADA called “ Disability rights aspects of ambient noise for people
with auditory disorders under the Americans withDisabilities Act,” this section mentions hyperacusis by name.
“ HYPERACUSIS AFFECTS 19 MILLION (5.9%) AMERICAN ADULTS.
Hyperacusis, discomfort from sounds that would ordinarily be acceptable to most normally hearing people, is not well understood.” The ADA also acknowledges that current treatment options are not very affective in treatment in hyperacusis. Hyperacusis treatment includes sound therapy and counseling, such as cognitive-behavioral therapy. “These treatments rarely work. Even mild hyperacusis can cause major life disruption.”
According to the ADA the definition of a disability is “defined in the Americans with Disabilities Act (ADA); a disability is a physical or mental impairment that substantially limits one or more major life activities.”
Hyperacusis Research also partnered with quiet collaboration an organization dedicated to reducing environmental noise levels. The new recognition of Hyperacusis under the ADA is a major step forward for Hyperacusis patients in receiving necessary accommodations.
“Furthermore, the ADA standard is that “no individual shall be discriminated against based on disability in the full and equal enjoyment [emphasis added] of the goods, services, facilities, privileges, advantages, or accommodations of any place of public accommodation.”
Some doctors have written letters for their hyperacusis patients that entitled them to receive accommodations in the workplace or in other aspects of life. Some patients with hyperacusis have also been able to win their case in court for disability and or other accommodations. Although there are noise laws and guidelines, they generally only apply to dangerous levels of noise.
Hyperacusis patients, however, experience pain from sound at levels much lower than are capable of causing hearing loss. Although hyperacusis has now been recognized under the ADA, there are currently no specific accommodations.
The hyperacusis accommodations implemented usually depends upon the person. There are also general disability accommodations that many people with hyperacusis use these include but are not limited to: grocery delivery, disability, an adapted work environment such as working from home, help doing noisy tasks, smaller adapted classes in college, etc.
