we got the bat detector out, and it does indeed produce an ultrasonic
noise, but pet rats at least arent bothered by the noise it produces.
The other thing to be aware of with these devices is that just because
they are out of your hearing range does not mean the sound pressure
isn't capable of damaging your hearing.
