pressure build-up ring

The pdf for the MKH20 states that:
=A0"o High-frequency response can be accentuated by means of a pressure bui=
ld-up ring=A0"
http://www.sennheiserusa.com/newsite/pdfs/mkh20.pdf

Can someone say what this is, how=A0 it is applied, and how much hf respons=
e enhancement can be expected? I'm going out hunting=A0for the Hawaiian Bat=
 (a sub-species of Hoary Bat, whose echolocation call is said to be 15-30 K=
hz). The MKH 20's freq response only goes to 20Khz.

Thanks,
David
