John,
Indeed that is the "notorious" Coqui (an onomatopaeic name), see
http://www.hear.org/AlienSpeciesInHawaii/species/frogs/index.html#frog
calls
They got to Big Island in nursery plants some years ago, and are
appearing on all the islands now, arriving here on Kauai ~5 years
ago. Most of the attention this frog gets stems from its very loud
call (90-100 dB at .5 m) which tends to disturb everybody's sleep.
People love it in its native Puerto Rico, I read, but here we fear it
will invade upper elevation ecosystems and devour endemic insects,
encourage rats, etc.
Aloha,
David

High sensitivity, means good low-noise results with commonplace mic preamps=
.

Very high sensitivity.

The noise specs are hard to compare because not all state what
filtering they're using.
