Peter,

See my other email about using acoustically transparent covers. A film
cover, however light, is in effect another microphone diaphragm which
re-radiates the sound. I've tried it and couldn't make it satisfactory.

Try holding clingfilm above your head and you will probably hear the
problem. Rain will also be very noisy and wind will make it very rustly.

If a fine fabric gets wet, rain can close the pores, but treating it with a=

waterproofer helps a lot.

PS. I invented the "rainsock" in the 1960's for filming a BBC Police Series=

in rain (low budget) which has since evolved into the ubiquitous "hairy
Harry" or "dead cat".
