Re: Bat detector

I've used the Anabat detector from Titley Electronics.
It's part of a system that includes software to analyze
the recordings, and to transpose them to a range audible
to homo sapiens.

Their web site is

Incidentally, it's good that bat vocalizations are beyond
our normal hearing.  The sound pressure level can be as
much as 120 dB, depending on the species and how close
you are.
