Sounds of people eating or chewing. There's a phobia for that I believe, but I know people that like to chew on lollies and it really gets me into rage mode. I usually turn up the volume to prevent it from reaching my ears

Living with a brother who chews in an excessively loud way....

I don't think its a phobia for me, I feel it more like sensory overload, especially if Im trying to focus on something and theres these repeating sounds like chewing, or pen clicking, foot tapping, cars... Whatever... Drives me insane, the only cure is putting on music on high volume with headphones. From what I know this is also a symptom on the autism spectrum or ADHD possibly.
