Phonophobia

Lol I'm just watched a Flamingo video of him playing this Roblox game and I thought it looked really cool and would make for a good story.

Basically, a group of people are forced into some sort of sick game and they're being chased by something- some kind of pale, fleshy creature. Thankfully the creature is blind, but when it roars it can see you. It can most definitely hear you always. You have to stay quiet or the thing will come...

Phonophobia is a fear of aversion to loud sounds.
