Great for concentrating
I actually got this machine because I get distracted by noises around me when I am trying to focus on an assignment (be it work or school).  Even with being in a separate room with the door closed, your still able to hear voices and sounds.  It wasn't an option for me to have an empty house every time I had to work on a project but if people were home and talking or of they had the TV on - it was just inevitable that I'd hear the TV for one second and then it was like my brain tuned into the TV and the muffled sound from rooms away took my attention from what was right in front of me.<br /><br />Now, when I have work to do, I plug in this sound machine and it makes a non-annoying noise that just blocks out any background noise (like people, radio, TV, etc).  Now this is an essential for me.  I pretty much plug in my laptop and my sound machine at the same time!<br /><br />I would most defiantly recommend this product!
