Thanks Josiah and Mayflowers,
For noise, I bought a subliminal ausio (InnerTalk) with ocean and other natural sounds. I use that and seems to be working well.. except that after a while I start to get buzz (I much prefer silence to any type of noise)... but this might work. Plus, hopefully I will get some benefits of subliminal as well.
I will try to get a poster of a water fall (like Niagara falls or something) and put that in North for running water.
