I remember I was screen sharing while troubleshooting something at a new job. I hadn't really set up my mac, and most everything was still defaults until I got a working build/deploy. One of the founding engineers said "You should turn bells off on your terminal. If [the CTO] sees that, he will give you so much shit." I should have taken that weird but ultimately innocent interaction as a sign that I was walking into an absolutely insane environment.

It's a tangent, but the bell character is a left over from how people used to do what you are asking for. Your question just reminded me of that strange conversation and harsh reaction.
