Thanks, Michele. That's an interesting idea. Definitely something I will co=
nsider for student research projects. The fact that the mic cones are verti=
cally oriented would seem to make the waterproofing easier to accomplish th=
an with horizontally oriented mics. But I'm surprised it lasts 4 months in =
the field!

Hi John,
your projects sounds very interesting! I don't have any first-hand advice t=
o give you, but recently read=A0something that could be interesting for you=
:
http://www.oldbird.org/mike_home.htm
this is the design of a boundary microphone to record night migrating bird =
calls. As the device is typically placed in open and exposed places, the tr=
ick seems simple but functional as recording sessions are migration long, 3=
or 4 months. Anyway others could have better ideas.
If you come to a solution for your autonomous recorder I would be pleased t=
o read the results and design as I'm interested in the matter too!all the b=

Subject: [Nature Recordists] Weatherproofing Mics?
=A0 I would like to build an autonomous, weatherproof recorder using a Pe=
lican case, an Olympus LS-7 (because of its timer function) and EM172 capsu=
les. I'm imagining somehow mounting the capsules on either side of the case=
, perhaps flush with the sides to get a little bit of a boundary effect. Do=
es anyone here have experience trying this and having success creating a we=
atherproof and wind-protected mounting for the capsules? Are you willing to=
share your experience?
I have been using a Wildlife Acoustics SM3 recorder, and while it is very r=
obust, completely weatherproof, and has a very flexible timer system, it is=
also very noisy, much noisier than I am used to with my homemade EM172-bas=
ed boundary array. It is also fairly expensive, and if I can create somethi=
ng at a lower cost I can deploy several of them simultaneously. But the sel=
f-noise is the main thing.
Thus I am hoping to recreate the EM172 boundary array - or something simila=
r - in a waterproof package using off-the-shelf components. I can figure ou=
t most of it, but I have never figured out how to waterproof an electret ca=
psule. Is it even possible?
Any ideas or leads to online resources would be greatly appreciated.
=A0Many thanks.
