I'm pretty tolerant of sound normally, so just it isn't enough to return it, but I had a really odd occurrence last night that might make me change my mind if it happens again.This is well above Apple’s specs. In my opinion, your Studio is faulty and should be returned.
I got a message that the "data" volume had been taken offline without ejecting it. Well, the only "data" volume I have is the internal SSD, and there's no way it should have been taken offline, ever, and I know I didn't do anything as I was asleep. However, it was running just fine so it must have come back online. Very weird, I've never had any Macs that did that before. Running first aid on the data volume took a long time but didn't find anything to fix.
