Whats the quietest air pump

when we got in the new whisper air pumps (the blue ones with 4 legs and rubber feet) where i work (at a pet shop) the owner wanted to try them out to see how quiet they really were. so he put it on this old wooden stool we had and i said, "plug it in", he said, "it is". i couldnt even tell it was on. i even put my finger over the hole, and then you could just barely hear enough to tell it was on. the pump uses special casing and design to eliminate all noise, and it does just that. i will be buying one this week for my goldfish tank that is right next to my bed.
 
This one?

The design dose look like its pretty quiet
 
thats the one. ill be getting the one made for 100 gallon aquariums for my 55 goldfish tank this week. i was stunned at how quiet it was. if you print out the price form petsmart.com and take it to petsmart, they will give you the cheaper online price for the one sitting in the store, in case you didnt know.
 
I've used air tech pumps, aqua-culture pumps, and hagen maxima pumps. The air tech pumps are kinda noisy. I needed one quickly, and I bought a couple 10 gallon air tech pumps for about $6 at petsmart. They are great to have on hand in case of emergency circumstances.

I keep mine on rubber mats. I run a 40 gallon aqua-culture pump for my 29 gallon. I have a cabinet stand and stick it inside the cabinet and then run the airline out the back of the cabinet. I don't even hear it and its in my bedroom. Of course, if you stick a pump inside your stand you want to make sure you have a good check-valve.

My 10 gallon does not have a cabinet stand- so it just has a pump on a rubber mat next to it.

I have a couple maxima pumps that I'm not even using right now. Of course, I have an extra heater and stuff, too. I'm kinda paranoid.

Anyway, little rubber mats work great. Or you can use the rubber gripper things that you can buy for opening coke bottles.

Good Luck!
 
just a 6" air wand at one end of the tank. here is a pic of the tank. there are now 3 goldfish, one died of unknown causes. that is live lucky bamboo in the vase. no gravel because round bodied goldfish can develop swim bladder disease if fed floating food. and if the gravel is small enough for the sinking food to not fall between the gravel, its small enough for them to accidentally swallow it and that can cause an impaction. i use 3 whisper 60s. it does have the hoods now. the bottom tank on the left is a 20 high with a breeding pair of convicts and their babies. the other tank is a 10 that will be for babies once the other tanks overflow (there is a tank of breeding platies that are also producing babies right now).

i have the one in bryce and tip's comments and it's really quiet- the only time it makes noise is when something touches it. it's on the ground in my office so it's on carpet, that probably helps.
