That's a broken mike. Probably due to moisture that got absorbed due to
contamination. I'd probably call that "rumble" if it's what I'm thinking
it is. It's usually a sign the assembly facility isn't so clean.

There's no testing procedure to provoke it?

Plug in a preamp and listen on headphones. If you hear it rumble, don't
buy it.
