Yes they/them is on ignore.
Too much noise. Pun intended!!
Already answered it's question in the cymatics thread, but from AI:
Noise canceling earbuds work by using tiny microphones to detect external sounds, then generating a sound wave with the opposite phase (inverted) to effectively cancel out the unwanted noise through a phenomenon called destructive interference; essentially, the earbuds "listen" to the ambient noise and play a sound that directly opposes it, neutralizing the sound waves reaching your ears.
