well, yes and no. any practical pzm has rubber pads to protect them from
floor vibration. the mousepad i used had a rather hard surface, and soft
rubber underneath. actually just used the pad so that i could move the
microphone around and protect it from scratches and other damage. i'd
expect the lf absorption of that pad to be pretty minimal, particularly
since its area is so small compared to the relevant wavelengths. so the
relevant boundary here is the floor, not the pad.
of course, high frequencies are messy, but as i said, with a bit of eq,
for this particular application it worked.

Except that for a PZM you need a hard surface. i got this idea when i had to capture an african
drum and was constantly
missing the fundamental. with no omnis at hand, i improvised one. what's
worse, i even shoehorned this bastard omni into a pressure boundary
microphone by taping it onto a mousepad and putting it on the floor.
sure, there was coloration, but for that particular drum, it worked.
So that is what mousepads are for!
