Decrease the sound level of biochambers

[470lm]

My enviornmental sounds is at 40%, at which I can hear every machine nicely, such as steam turbines, accumulators, assembling machines, etc. but the biochamber is way too loud compared to other machines. I had to set environmental sounds to 10% so those bubbly noises are on the same level as an assembling machine's, but now I can barely hear all the other machines, and accumulators are practically muted now

I've turned it down a few dbs.
