Perfect for work, sleep and even a puppy!
We have one of these outside each main office at work.  It really works to keep what's going on in each office private and &#34;separate&#34; despite our thin walls.  And it just creates a nice calmness.  You don't notice it's on.  But you DO notice when it's not on.  It's the perfect background noise.  Just got a DS for at home to sleep with.  I've now had the two best nights of sleep ever and it even keeps the puppy calm when she's in her crate.  Love these things!
