Loud fan white noise
It's like having a super-loud fan in the room, without the air blowing. I love it; I think it blocks out neighbors and the TV in the other room and occasionally, even my husband's snoring. But he hates it, thinks it's too loud, and usually turns it off, which defeats the purpose. There's no volume control; you can twist the side and the top to alter the sound somewhat, so I made it lower instead of higher, but that wasn't enough to get my husband to leave it on.<br />I think it's much too loud to take to work in a cubicle setting.  I was hoping to take it in to drown out annoying co-workers, but I can't imagine everyone would put up with the sound and I'd be "requested" to turn it off.
