How quiet is quiet?

hi, Roger,

This may come across as being an odd question. The Tunze 230/3 skimmer is currently in the frontrunning for my choice of skimmer on the 120 gallon tank I am putting together. It'll be primarily an SPS/LPS tank, with a very light stocking of three small fish.

Aside from skimming power, my biggest concern is noise. I understand that the Tunze skimmers are extremely quiet and energy efficient. Has anyone ever sat down with a sound pressure level meter and measured the intensity of the sound given off by the skimmer from say, three feet away? There's very little chance that I'd get to see a Tunze skimmer in person unless I order one.

Ideally, I'd want to be able to put the skimmer in my cabinet, on the side of my sump, close the door, and not hear anything. I don't mind sound proofing the cabinet or what not, but it'd be great to know how they compare.

Regards,

Jason
 
They border on absolutely silent. I don't know that I can put a decible rating on it, right at the skimmer you here a soft sound similar to a jet engine or turbo in pitch and type but maybe 35 decibels, quieter than a good airpump, from outside the stand you will hear nothing. The key is a series of baffles and silencers on the air intake for the venturi.
 
I have had this skimmer......it is absolutely just about silent!!! Best of all........it is easy to clean.
