How quiet is this? Is there a big hum from the motor?

We like our fan. Have it out on our patio. Have not noticed any loud noise. Very quiet! Hope this helps.

I think it is definitely quieter than other models. I have had 2 other machines and this one is decidedly quieter, not silent but more of a medium soft buzz.

It is very quiet. All I hear is a low hum when I am next to it and it is running. Remember, it is under water when it is running.

It isn't loud at all. There is a slight hum, but not one you really notice. If you ever heard a small fan, the ones you push the button and they blow in your face, it's kind of like that.

It's pretty quiet but on the flooring I have it on and at a certain fan speed there is a slight buzzing going on. If you need dead silence I'd suggest an oil-filled radiator. They essentially make no noise except perhaps a slight clicking when they cycle on or off.

It's really quiet and efficient. When the motor kicks on its really not load. I would compare it to about the same noise as turning a window ac unit.

I've found it to be quiet. It's not noisless but the sound is more of a smooth hum than anything halting or harsh. The actual volume of the sound is pretty low.

Its a high frequency PWM (15khz), so not audible in my setup. Im using it in a small motor so I cant hear any whine. Im not sure if this would be the case on a larger motor under stress.

For the most part it's quiet because other noises drown it out but when time for bed, if you're sensitive to sounds like me, you can hear a low hum. Most times I can tune it out, or maybe I'm just flat tired, so it's not a huge problem. But no, in answer to your question it's not truly quiet. My tank is about three feet parallel to where I lay my head and I can hear it.

Not very noisy, just a consistent hum, with the hum louder when on high speed.

Its not loud at all - I have it in my living room where my TV is as well and it barely makes more than a bit of a very light hum when it's running (I use the auto setting so it kicks on periodically when it needs to and usually in a low mode although once in a while higher). I can barely just hear it when there is nothing on like a tv or radio and sometimes miss it all together if I am focused on what I am doing. Can't hear it at all with the TV on.

It is not a silent focus motor. It makes a moderate degree of noise. Unless you're in an very quiet space, it probably won't stand out that much.

No really quiet or loud.... If you want power it makes noise, but less than a vacuum cleaner !!!

No this vacuum is at a decent noise level. I mean it's still a vacuum so it's not quiet. But not loud either.

very loud? well, mine is not silent, however it does hum a little (nothing louder than, lets say a refrigerator hum). besides the noise is it pumping water?

It is a quiet unit. You don't hear a humming, motor sound do you?That bubbling sound you hear is the ultrasonic process of water turning into mist.

I don't find it quiet at all but I've never had a generator before this one so I couldn't tell you if it's worse or better than others. I can tell you the noise from it is just like a lawnmower. It sounds like you've left the lawnmower running just outside the house. It's loud when I'm outside and right next to it but from inside the house with doors and windows closed it's not intrusive at all.
