Jokes aside, I'm trying to wrap my head around this one:
"By comparing sound levels with and without the metamaterial fastened in
place, the team found that they could silence nearly all -- 94 percent
to be exact -- of the noise, making the sounds emanating from the
loudspeaker imperceptible to the human ear."
Let's assume that percentage refers to sound pressure level, not
spectral width. Is it reasonable to expect something like 24dB damping
in a narrow band? That would be really nice, but not amazing.
Yet, if it's a high pitched noise they're battling, that probably
translates to "still very annoying".
Those evil log scales, here's why the press likes percentages better.
Unfortunately, our senses don't care.
