Just a quick notion -- while building blimping for various
purposes, I've found that you can get a fairly good idea of the
overall effect on passed signals by just holding a section of
material over your ears. In fact, I built a binaural windscreen
out of a pair of earmuffs many years ago, by carefully removing
bits of the fakefur muff's backing material. Just wearing the
muffs provided an effective way of getting an initial read on
how much attenuation they created. (The "listening" test doesn't
give much insight into the LF buffeting, however, since our ears
already deal with that amazingly well.)

Subject: [Nature Recordists] Wind Protection
All,
I am building a mount for a pair of Shure 183's and seek advice
on
the wind protection. My main concern is including to much
protection and restricting the effectiveness of the mic caps. I
will post photos of the parts and finished design but I am
describing the suspension as compact holders that suspend the
caps
in open cell foam, leaving the front of the cap open to the air.
The holder is then mounted on my headphones and worn while
recording. Nothing new, just a different design of the holder.
The experience that I have so far is that I can protect the mics
from a direct blast of air with two layers of protection and
prevent
clipping but I wonder if I should go lighter with the wind
protection to make the mic more sensitive. I know that I can
experiment and decide on my own but I am hoping someone can help
with their experience.
My most effective cover at this point is using the one inch long
foam cage supplied as a pop filter and then covering the whole
unit
with short artificial fur sewn into a small bag shape and
slipped
over the entire holder. I lack experience or means to decide if
this is too much protection.
Considerations for wind screen at this point are;
At what point will ambient wind noise in the grass and trees
spoil
the recording if the caps are protected from the wind?
At what point is the sound attenuated when adding layers of
insulation?
Are the foam pop covers effective for wind? The larger one is
designed like a mini blimp.
