Growing up, I thought it was just me that the sounds of people eating loudly or sipping, slurping on beverages only annoyed me. It literally drove me crazy. As I got older I realized that those noises bugged other people I was around as well. It was like nails on a chalkboard. It caused me to ask people to eat with their mouth closed and to stop sipping so loudly. I felt bad but better than exploding on them I suppose.

 

According to a survey on Reddit they surveyed people ans asked people to name common sounds that make them cringe.

Here are the top 5:

1.  Other people's mouth noises.  Like loud chewing, sucking, or snapping gum.

2.  Hearing your dog or cat puking.

3.  Utensils scraping on a plate, or across your teeth.

4.  A balloon being rubbed.

5.  A dog licking itself.

Then I learned sounds that are unbearable to listen to there is a term for it. Misophonia which means "hatred of sound", was proposed in 2000 as a condition in which negative emotions, thoughts, and physical reactions are triggered by specific sounds.

Misophonia is not classified as an auditory or psychiatric condition, and so is different from phonophobia (fear of sound); there are no standard diagnostic criteria, and there is little research on how common it is or the treatment. Proponents suggest misophonia can adversely affect the ability to achieve life goals and to enjoy social situations. As of 2019 there were no evidence-based methods to manage the condition.
