what is the noise level for various levels of operation in db?
70464
about average--if mounted or set on rubber/or foam pad it would be pretty low
70465
Which dB scale are the measurements you are seeking in? Since most sound measurements are unfortunately taken in the dB A weighted scale (even for automobiles) with 'eliminates' or 'removes' all sound frequencies below 500hz, as compare to dB C weighted scale which is essentially the same range as human hearing, from approx. 20 Hz to 20,000Hz. Since the "A" weighted scale removes so much of the possible audible spectrum, it's somewhat difficult to ascertain what the actual unit sounds like.

The owner's manual states that the noise rating is 58.5 db at the highest speed (turbo). It's much lower in "normal" mode.

I measured 86 dB right below my fan on high. Belt drive is supposed to be quieter. Higher quality is quieter too, but much more expensive.

On a noise level from 1-10 this would be between 4-5. ~Thank you for shopping with Vert Delivery!

This pump is very quiet, one of the reasons I picked it. I don't have any idea of the decibel level.

The noise level is moderate and what would be expected for what the machine does. The noise has not been an issue for me.

I have no idea what the DB rating is for this unit. However, I was surprised at how quite it seemed in comparison to the ones my neighbors have.

I cannot say for 100% certain. It seems reasonably quiet (certainly NOT silent), but I'm running it in a server room with a couple of servers that kick out major decibels, so I don't have an accurate sense of this machine's noise level. Sorry.

I wish I could answer your question accurately. I am using this unit out in process line to help dry some product that I am running and because of the back ground noise cannot really tell if it is loud or not. I can tell you that the quality seems to be of high standards.

Without a digital decibel meter with which to measure the various levels-I had to resort to the Analog measure test, which resulted in: Most Quiet-More Quiet, and Quiet..I hope that is helpful---:)

I heard a lot of noise as well, that is before i bought a dedicated audio interface, like an m-audio m-track, preSonus, focusrite, etc.. If you're not using one, then i'd say get that first. I have no noise now at all settings. From -30db, and i usually have my speakers set at the +6db and nothing. i'm also using the 1/4" to 1/4" plug into the balanced inputs. If you're using an audio interface, then i'd say call customer support and get it fixed.

I do not have any information on DB rating of the heater or any way to measure it. However, I can say that the level of sound from the heater is dependent upon the mode it is operating in. When operating at full output, the fan is operating at high speed and thus generates a level of sound consistent with any fan operated room heater which I would classify as moderately noisy. When operating at "idle" speed it is very quiet all of which is dependent upon the thermostat setting relative to room temperature. If you desire a very quiet heater, then I would suggest a radiant type heater that does not have a fan. I do not have any information on DB rating of the heater or any way to measure it.

the noise level is quiet. we have ordered several since employees like the unit so well. hope this helps. fits great under the desks

Thank You for the reply. yes I did mean DB the settings are 0 DB and -3Db I set it at -3db for now. I am till waiting for my sub to arrive. I got a Alpine SWR-T10 10" 1800W 4-Ohm Type-R Shallow-Mount Car Audio Subwoofer. I will take your advice thank You

do you mean db?if so you may want to use the 0 db setting because the 3+db setting may be too over tinty(but if you use a good sub you may want the 3+db setting for a little more highs) remember this every 3db doubles your power(it could be too much highs for your system).but test and see what your thoughts are(try both).

I would rate the noise level as medium. Not exactly noisy, but not whisper quiet. It's a great machine. Very efficient and worth the money. Great suction power.

I didn't notice any unusual Buzz when I first powered up the unit in my shop. My opinion is is the noise level is normal....

The ambient noise level in my house runs about 49-50 db. If I start talking, the level rises to 60-62 db. I think the unit is pretty reliable and accurate.
