My watch has a “Noise” app: it shows dB, for decibels.My amp has a volume knob, which also shows decibels, although.. negative ones, this time. And finally, my video editing software has a ton of meters — which are all in decibel or decibel-adjacent units.

Are the decibels from my watch and the decibels from my amp related? And if so, how? I’ve decided to spend twenty minutes of your time answering that question.

I’ve also spent about a month of my time making FAM: the fasterthanlime audio meter, in Rust of course, with egui.
