I don't care
I'm aware, but not annoyed
I'm quite annoyed by the sound
I can't stand it
Eating sounds like chewing, lip smacking, crunching, slurping, swallowing
Finger/hand sounds like finger snapping, finger tapping, fingers drumming on table, knuckle cracking
A large truck or bus driving by while I'm on the sidewalk
Traffic noise from inside my home or another building
A car horn when I'm inside of a car or another vehicle
