Mine makes a very quiet high pitch sound, but you have to lean close to hear it.

No sound is produced from this item, totally relaxing to watch and very quiet.

I think that it is very quiet. I only use it to backup my system and it is not on all of the time. I have not noticed any noise.

No, it doesn't make much noise. The unit is heavy enough to minimize vibration to the floor. My wife easily watches TV in the same room when I'm using it.

no noise at all -- I never notice that it's on. I currently have mine in the family room just under the TV.

It does make a noise. It is steady. I sleep with it on. It is an awesome machine. I highly recommend it.

It's silent if you turn it on without movement. If you let it oscillate, you might hear it move, but it's still nearly silent even then. I'm not sure I hear it even when oscillating.

It is kinda noisy. I have it in my dining room and not bedroom so have not tried to sleep with it on. Noise depends on the level of diffusion that it is set to.

I do not hear a lot of noise. I have noted as it is on longer. It does not beep.

Mine is quiet but it depends on which setting you use. If it's on the lowest and is still very loud then there is an issue.

It's quiet I've left it on overnight and had no issues. I couldn't even hear it in my own house

No, it dose not make any sound at all. I love it. There is a timer and there are multiple choices that you could choose. It is very compact so you could close it up and put it away.

Very quiet.I have it on right now and can't hear a thing. Just 2 feet away.

Admittedly, I have the smallest unit, but it is absolutely whisper-quiet. I can hear it a tiny bit if nothing else is on in the room. If anything, it's a tiny bit of white noise (which is a good thing at night, as it masks other noises).

It is pretty quiet, and it is under the foot of the bed, so I only hear it if I turn it really high.

Actually, no. It's quiet silent. I was surprised to hear it. I thought it would be way more noisy.

It's more like a very small fan. I'd say it is relatively quiet. It's not a rattling sound or anything. I usually use mine at night so it's ready by morning.

It is very quiet. I don't like any noise when I sleep and sometimes I put this unit on my nightstand and it doesn't bother me. When it is in our family room I don't even notice that it is on.
