Best White Noise Machine
This white noise machine is superior to any of the electronic models.  It masks noise much better and there is no annoying repeating pattern.  I am purchasing a second one for when we travel and have the kids in another room.<br /><br />Even though there is only one speed setting, you can adjust the sound pitch and volume to some extent by adjusting the air vents.  In my opinion, there is really not much reason for having the second speed since you can also just put it further away to reduce the noise level.
