How far in to the infrasound do you need to go? Many good omnidirectional=
microphones have a frequency response which extends well below 20 Hz. My o=
wn
tests of microphone frequency response usually stop at 10 Hz, but there's n=
o
reason why I can't go lower.
Don't try to make an infrasound recording using either cardioid or Fig8
microphones; despite what some mfgr. web sites show, pretty much all of the=
m
roll off below about 150 Hz or so when used at a distance.

I am in need of a good infrasound microphone. I do own the SD722 so
assume I have the correct field recorder to record infrasound.
Thanks,
