I've been in places where getting out of the car my first act was to put
on the headphones, the sound was definitely painful!

However, the same sonic effects do also occur at lower volumes. Except
for the one where you ears are being destroyed. Then you do get things
that won't record.

The interesting thing to think about is that frogs have fundamentally
the same problems of hearing destruction from loud sounds. How they can
still hear is a interesting research subject.

Insects tend not to get beat frequencies as much as frogs, or I don't
hear them as much because of the higher frequencies. I think primarily
because their frequencies are a bit more consistent, hard wired in their
genes more or something. But, where you have long callers you can hear
this. And, of course phasing due to multipath from the environment does
exist for them.
