Just found a cool site with great background noises! (in case you work with those, for me it really helps) mynoise.net/
There are so many choices and even have the option to edit it to your liking. Sorry, I'm just very mind-blown by this because normally I use www.noisli.com/
which is also a great and very simple one, but it doesn't have that much variety. It's super cool, I just had to share it with you guys!!
