Bob,
Let's say that the reflector is 10 square feet, so all sound impinging on
that area is concentrated down to his ear due to the nature of the
parabolic shape. The gain of this operation could easily be 100:1 if the
ear catches only 0.1 square foot.
Yes, but my point is that the source / person is not 10 square feet!
