Hello,

I'm using an Innovative Specialists twin gooseneck microphone with AT853 cardioid capsules in an ORTF configuration with an HV20 and I need some wind protection. The capsules and bodies are only like 12mm in diameter. I found an old article online (http://scienceservice.si.edu/pages/090002.htm) about a material called Acoustifoam developed at the behest of Electrovoice for use as windscreen material. The stuff is "open-pore" polyurethane foam, developed by the Scott Paper Company, Foam Division, and the circa 1964 paper linked makes it sound pretty good. Anyway, B&H sells a couple (http://www.bhphotovideo.com/c/product/76707-REG/Electro_Voice_3141273_314E_Windscreen_Pop_Filter.html)
Electrovoice windscreens made from the stuff and I wondered if it'd be worth $20 apiece to get a couple, even though they'd be a bit big for my bare mics. Anyone have any experience with this stuff?

Thanks!

$20 for wind protection is a cheap investment. Go for it and let us know how it works.

Or go to the local radio shack and try their stuff.
