I have an acoustic device that operates in the 17-19Khz range. I want
to know what would be a good surface, that can be found easily
(nothing fancy) or is in everyday use, which will be a good reflector
of the sound energy (I need it for a wierd reflection test that I have
to do, but that is beside the point over here). I was using walls in
our lab, but that seem to absorb a lot of energy, My next idea is to
probably use something like a metallic dish, but wanted to ask the
question in the meantime.


Will appreciate any advice

Thank you.

Sounds like glass would be ideal. Grab a mirror from the mens room.

or pry one of the tiles off the bathroom wall
If you need a concave surface, the urinal would be ideal.

What about the wife's granite bench top? Or a marble
headstone from the cemetery ;-)
