Diaphragm air pump. Bought two and never looked back. Very quiet and dependable, I've had one running continuously outside for a year with no noticeable reduction in air flow.
Here's the pump we bought for multiple buckets http://www.amazon.com/gp/product/B008UF9XLY?psc=1&redirect=true&ref_=od_aui_detailpages00
You can even tee them off to do 8 buckets.
Unless its a commercial air pump, which you dont need for 10 gallons it should be whisper quiet. Look into the Eco whisper series, they come in various sizes, all of which are quiet until you get to the commercial level. IF you feel you need heavier air output from a commercial size BUT you also need it quiet id go with https://www.amazon.com/General-Hydroponics-Dual-Diaphragm-Pump/dp/B008UF9XLY
Its what I use indoors for DWC 60 gallons across 4 reservoirs and it does fine.
TLDR; Your pump can be small enough that you shouldnt even hardly hear it running if at all
Yeah my two air stones are bubbling away now with [this] (https://www.amazon.ca/Marina-11116-200-Air-Pump/dp/B0048AOQK8). Its a pretty basic air pump but it seems to be going alright. It's only aerating about 7-8 gallons of water. Its replacing my old pump that broke.

^ best quietest pump i've owned, so I bought a second to replace a Fluval, because it was quieter. Only downside is no 3/8s outlet. Also pumps and temperature of the air being pumped stays fairly low.
I own an EcoAir 950 gph single piston thats not allowed in the house because its so noisy, its solely for compost tea in the garage. Ive used mostly Fluval pumps as they were quiet, but they didnt quite have the airflow I wanted, also ran a few Pawflys.

Like This?. Have you used this pump? How many do you think I need for my system? Looks like regen blowers pull way too much current.
One stone per container is fine. I would buy a better pump like this one https://www.amazon.com/General-Hydroponics-Dual-Diaphragm-Pump/dp/B008UF9XLY and use that to power all the pumps. I have about 5 of these and they work great.
