Hi Guys! My google skills are failing me at this.

I’m looking for an indie horror film, probably American from somewhere 2010 on. It’s a friends-go-camping horror film where mysterious sounds cause the friends to go deaf, have vertigo, and I think go crazy and kill each other. I seem to remember a super disappointing ending where it was aliens or something? However, the creepy sound aspect of the film was super rad, hence me wanting to find it again!

Thanks so much for your help!
