We aren’t sure what causes misophonia, yet.

Misophonia is not considered to be a phobia. Phobias are irrational fears of specific things or situations, while misophonia is a sensory disorder that causes strong dislike or negative emotional reaction to specific sounds, such as someone eating or breathing loudly. Misophonia is often described as a disorder that is a multi-sensory sensitivity and can be difficult to cope with in some cases.
