Picking up a rat colony tomorrow. Have a question.

So my feeder supplier is getting out so he can travel and do stuff with his wife. Happy for him, but sad for me lol. He's selling me what he has left of his breeding setup (An ARS 70, 6 high rack, with watering system, 50 rats, gas chamber etc.) I initially was planning to put them in my garage as it doesn't get too cold in winter, and I can use a swamp cooler on the really hot days... Well I thought of a potential problem. Will loud noises be a detriment to the colony? I keep my riding mower in the garage, and I also do wood working, welding and other fabrication in the garage as well. I was wanting to hear from people with more experience with rodent colonies (I've never kept more than 4-5 females at any point).

The benefit of using the garage instead of the basement was the obvious benefit of not smelling rats, and also the upkeep will be far easier in the garage, cleaning tubs and disposing of dirty bedding.
