Kiya:

Noise is a huge trigger for most people suffering from PTSD.

Personally, my nervous system is so overtaxed and beat up, I need total peace and quiet. I get pissed when one of my neighbors drives into our complex with his windows opened, blasting rap music. The base just drives me off the wall. I feel like going out with a baseball bat and smashing their heads.

Because of my issue with noise, I have been forced to give up many things I always liked: football games, concerts, parties, wedding receptions, large restaurants, etc.
