A 'supersensitized' brain connection may be why you hate the sound of loud chewing, study finds

People who have an extreme reaction to certain noises, specifically loud chewing and breathing, may have a'supersensitized' brain connection, a new study reveals. Scientists at Newcastle University discovered an increased connectivity between the auditory cortex and the motor control areas related to the face, mouth and throat in those suffering with misophonia. Misophonia, which means'hatred of sound', is a condition in which people experience intense and involuntary reactions to certain sounds made by others, referred to as'trigger' sounds. The findings suggest that misophonia is not an abreaction of sounds, but'manifestation of activity in parts of the motor system involved in producing those sounds,' according to the study published in the Journal of Neuroscience. Dr Sukhbinder Kumar, Newcastle University Research Fellow in the Biosciences Institute said: 'Our findings indicate that for people with misophonia there is abnormal communication between the auditory and motor brain regions - you could describe it as a'supersensitized connection'.

Why the sound of noisy eating fills some people with rage

New Scientist

Imagine feeling angry or upset whenever you hear a certain everyday sound. It's a condition called misophonia, and we know little about its causes. Now there's evidence that misophonics show distinctive brain activity whenever they hear their trigger sounds, a finding that could help devise coping strategies and treatments. From the age of about 7 or 8, she experienced feelings of rage and discomfort whenever she heard the sound of other people eating. By adolescence, she was eating many of her meals alone.

Many of us find the sounds of our loved ones eating annoying. One sufferer of the condition, called'misophonia', said she feels like punching people in the face when she hears the'trigger sound' of family members crunching on crisps. But when she went to her doctor, she said he laughed in her face. Now scientists have shown that the condition has a real biological basis and goes way beyond simply being irritable. Brain scans show that people who find the sound of chewing, breathing, or numerous other conditions unbearable have a genuine brain abnormality.

Margot Noel has a condition called misophonia, which literally means "hatred of sound". It can be so disturbing that she has to wear headphones or ear plugs to protect herself. There's a drawn-out crunch as the teeth break through the tough skin of the fruit. "I have to leave or cover my ears. I just cannot hear it," she says.

Misophonia: Scientists crack why eating sounds can make people angry

BBC News

Why some people become enraged by sounds such as eating or breathing has been explained by brain scan studies. The condition, misophonia, is far more than simply disliking noises such as nails being scraped down a blackboard. "I feel there's a threat and get the urge to lash out - it's the fight or flight response," says patient Olana Tansley-Hancock, 29, from Kent. UK scientists have shown some people's brains become hardwired to produce an "excessive" emotional response. Olana developed the condition when she was eight years old.
