Misophonia

Why do certain sounds bother some people?

Some people are bothered by common sounds that don’t bother others, such as noise from chewing. The technical name for this disorder is “misophonia.”

For many years, misophonia has been thought to be a psychological problem, but new research shows that the problem may be neurological in origin. People with misophonia have differences seen on brain scans from those without misophonia.

Medical science is replete with examples of diseases thought initially to be due to psychological causes, but later found to have biological bases. For example, stomach ulcers were long thought to be caused by stress, with a contribution from spicy food or alcohol, but then they were found to be caused by bacteria.

In the auditory field, hyperacusis–a sensitivity to sound, in which noises that don’t bother others are perceived as painful by those with this condition–was also long thought to be psychological. Then researchers found pain fibers in the auditory nerves, and the biological basis of this condition was better understood.

So kudos to the researchers studying misophonia. For those who suffer from this disorder, having the science world focus on identifying the biological basis for the problem may be the first step to treating it.

There are three main auditory disorders: hearing loss, tinnitus, and hyperacusis. But there’s a lesser-known fourth one, misophonia. Of these, only hearing loss is well understood, with the others understood in decreasing order as listed. And misophonia is often dismissed as a mood disorder.

This piece by NPR sheds some light on misophonia, the little-known and least understood auditory disorder that’s marked “by intense emotion like rage or fear in response to highly specific sounds, particularly ordinary sounds that other people make.” High on the list of hated sounds are mouth sounds like slurping and chewing, which makes life difficult for people with misophonia.

One hopes that other media pay attention to disorders like misophonia and approach the topic as thoughtfully as NPR has.

Living with misophonia

Natalie Reilly, NZ Herald, writes about living with misophonia, the “hatred of sound.” Eating sounds are particularly enraging for Reilly, and she confides that she hates hearing her husband eat. Which could be a real problem, except he suffers from misophonia as well and, well, he hates the sounds she makes when she eats. And so this couple have found a solution to maintain marital bliss: one eats in front of the tv, the other eats in the kitchen.
