Back in the mid-2000s or so before 2FA was really a thing, I built a small perl script to have my server do audio beeps using the PC speaker based on some activity in the system. The idea was I sat in my office near enough to my servers at home that I could hear audio beeps. I also had patterns of sounds so that each type of activity was a different noise, e.g.: SSH logins would produce one pattern, local login a different set, etc. I've long since lost the script but I've seen a few similar ideas kicking around over the years. Really only applicable to homelabbers I imagine and probably easy enough to throw together again.
