I'm not sure on Lyrebirds, it's been many years since I heard them in
the wild. They are loud for at least some notes.

I do carry a sound meter around with me here. And it does not come close
to 140 on natural sounds. This is well above the threashold of pain.

I do know some frogs have been measured at close to 130 dB at the frog.
Of course that dies off quite rapidly with distance. There have been
some interesting studies done on how a frog like that does not go deaf
from it's own calls as their hearing is as vulnerable as ours.

I have been out in a few frog chorus' that were above the pain threshold
for me. I was glad to put the headphones on to monitor recording. And
the Telinga did not overload.

Yep I thought about that with that discussion, may be longest day here,
but for you it's shortest.
