ME67 etc: Principle: Sound from the front of the mic hit the frontside of
the membrane. The side-sound also go through the slots and hit the membrane=

from the back, out of phase.

Simple video mics etc: It is often a 10 mm (or smaller) electret with a
tuned resonance tube in front of it, causing some gain of the sound which
comes from the front.
