I have a great sensitivity to noise and use earplugs etc for sleep and have fans going, but unfortunately due to various limitations including finances, I need to stay where I am at present, which is next to both a police and fire station. It really is unbearable. I don't much mind the police sirens, like yelping ones, especially during the day, but do hate the "wail" ones used by firetrucks and ambulances at night, so those are the primary ones.
One of the things I try sometimes is try to listen to real loud music but that also causes me stress and does not exactly cancel out the siren noise which I can still hear.
Should I look for a particular frequency or decibel level or pitch or something? I really don't know much about sound I have downloaded white noise, brown and pink and a few others to try to figure out if any of them can mostly cancel it out so I don't wake up at night, but I have realized there is much to sound I don't know and decided to post here, hope it's the right forum, I guess I could also post in engineering or health related section, but either way, appreciate considerate and constructive help for my situation. Thank you.
