The University of Sussex is running what it says is the first ever randomised control trial into a neurological condition which affects millions of people.
Misophonia is a reduced tolerance to certain sounds, particularly those made by other people.
Often sounds associated with mouth, throat or facial movements that cause distress, as well as things like chewing, breathing, and repetitive finger tapping.
Alex Ayling, from Sompting in West Sussex, who has had the condition since childhood, says: “Some noises make me so angry.”
