Modern dimmers and LED replacement bulbs are much quieter (both electrically and mechanically) than old one’s, especially compared to LED lighting with plug in power adapters.
If you have new LED bulbs with old school, turn to dim controls you probably want to upgrade those dimmers, and I even recommend skipping new LED aware dimmers and going straight to smart switches.
I’ve found that the modern, but dumb dimmers are not only hard to calibrate, but tend to be far too voltage sensitive. After swapping out dimmers in my house a little voltage change from the AC or other appliance would cause the lights to dim or brighten noticeably. Replaced them with smart switches and those problems all went away.
