good job on finding ways to manage this anxiety. we too share that edginess when there are too many external noises that are beyond our control. we find things like traffic or noises that are just going to happen day in and day out more easy to get used to as they're regular and anticipated.

the human noises of leafblowers, music, auto repair, etc. tend to be triggering due to not knowing when to expect the next jolt. the anticipation of when a previously annoying noise will start up again can be our undoing when anxiety is already heightened.

some great ideas in this thread.
