Scientists do not fully understand misophonia but suspect it's caused by the way some people's brains process particular sounds and react to them.
Some studies found that the brains of people with misophonia showed hyperactivation of the salience network, a group of brain areas that direct our attention to important things in our surroundings. Trigger sounds send the salience network into an overdrive. Researchers found these brain areas are structurally more robust in people with misophonia.
There's a lot of similarity between people who experience misophonia, but also a lot of diversity.

The two theories that back this up are the Nice model and the Grand Tack.
The different types of asteroids are:
