I've done at-home hobbyist development for five years with the neighbors from hell revving exhaust modded beater cars 20-50x/day. I'm drooling at the words "deadly quiet". (And yes I'm leaving here at some point in the next year).
Ugh. You have my sympathy. For one who "put up" with similar circumstances for far too long, I hope you won't mind my sincere advice: Get out! Staying is a downward spiral -- I know.
