Now SlackOps encourages us to make the same mistake.
I never want an IM saying something worked. That’s just noise.
a) space
b) Sonos speakers
and c) a slack channel
All with the same person. And if I did, I'd probably just turn the speakers down and tell them it's too loud, then set the volume limit in Sonos.
In that spirit, it seems better to have a speaker that can't be set higher than the "approved" maximum. If this thing is measuring actual sound level rather than set volume, a slow release limiter, either in software or hardware would just make it automatically correct without the whole notification cycle thing.
