hi. i've got a very real life question and im wondering if this is the right place to ask it, but here it goes. i've rented an apartment which is next to the main street so i have trouble sleeping after 5-6am due to the traffic noise. since i cant make any serious modifications to the apartment cause i do not own it, i was wondering would it be possible to produce sounds which would help me sleep, which would actually "soften" traffic noises, or create some kind of counter waves which would reduce the street sounds? my idea was to automatize my laptop to turn on in the morning and start playing those sounds and continue doing so till i wake up and turn it off. of course, the trouble is i dont know much about physics or nature of traffic sounds, I mean, i can't experiment with them cause ive got no gear to do so. i dont know which software to use to maybe try playing sounds randomly and creating tolerable environment for sleeping in my bedroom. any kind of help, advice or guidance is much appreciated, so thanks in advance.
