Charger and USB
Plug in the charger. Hear it.
A tune when you plug the charger in or unplug it, and a sound when a USB device connects or leaves. Tappy grabs a snack when the charger goes in.

TapNoise hears when macOS reports a change to the power or a USB port, and plays a sound for it. Both are on by default. They work on any Mac that runs macOS 14 or later, and they don’t need a motion sensor.
Plugging in the charger also sends Tappy off to eat a snack. Unplugging the charger while Guard Mode is armed sounds its alarm, even with the charger sound turned off.
Both sounds follow your sound theme and your volume. Like every other sound, they stay quiet during calls when Quiet during calls is on.

Not while Quiet during calls is on, which it is by default.
Can I keep the charger tune but turn off the USB sound?
Yes. They are separate switches under Settings › Events.
