Re: Edmund Parabolic Reflectors

What does "thunk" mean?

I guess it is the parabola resonance itself? "Plonk" when insects hit it, 
for example??
It can easily be dampened to nothing with a piece of cloth covering the 
opening. There is a
special Telinga windshield to get for the lazy ones, without a needle and 
thread.

Or do I misunderstand?

Klas.
