The frequency at which air is best matched is about 40kHz, several things
with this:
- low resolution because of the low frequency
- going to take more power to get a given range of detection than using a
commercial grade unit (works at 40kHz) due to the impedance mismatch
- Every dog (and a lot of musicians) in the area is going to go crazy when
that thing is turned on
It'd be interesting to find out where they got their transducers and what
they were intended for before they got dumped here...
