I'm thinking about setting up a Sonos system in my master bedroom to drown out traffic noise. The idea would be to connect a streaming device via Bluetooth and play loud but peacefull sounds, like rainstorms, waterfalls, etc. I do this already with a small sound machine and it works ok but would really like to totally surround the bed and have flexibity in what I play.
I am assuming that I don't really need any bass for this and wondering what type of Sonos system would work and how many speakers/ what equipment I would need. Note there is no TV in the room.
