Anything over 60 decibels.
Squeaks like chalk on a blackboard.
Any sound lulls and then pounces with aggression - designed to cause fear.
Mechanical pings, beeps, etc.
Voices with unclear diction.

Omg the Mario racing melody. Stress. Automatic and intense stress I can’t live with in my life

Trains. I've heard them for most of my life rumble on by.

The sounds of when life got depressing

Traffic commute or dog barks.

The sound of raggidy breathing

The voices of street vendors who keep wanting me to buy their crap
