As Dan points out the ‘hogs hair’ filter material is very effective at removing 
the loud plop of a raindrop.  It is however, not waterproof – so it needs a 
backing of something to stop the water filtering  through to the windshield or 
microphone.  I find novelty ‘Umbrella Hats’ very useful for this purpose. They 
are cheap, pack-up small and are very light.  They fit perfectly on binaural 
dummy heads and can be easily modified to fit a Rycote or Rode blimp.

 

See for example 
http://www.ebay.co.uk/itm/FOLDABLE-NOVELTY-UMBRELLA-SUN-HAT-GOLF-FISHING-CAMPING-FANCY-DRESS-MULTICOLOUR-/181748953909?pt=LH_DefaultDomain_3

 &hash=item2a5114f335

 

In the UK ‘hogs hair’ filters can be most easily obtained as filter material 
for fish tank pumps.  Larger sections can be obtained from The Foam Shop who 
call it Reticulated Foam - 
http://www.thefoamshop.co.uk/category/193/RETICULATED--FOAM

I find the 10ppi reticulated foam which is about an inch thick to be very 
effective at dampening the noise of raindrops.

I've found that faux fur will keep one night of rain away from my WL183 
electrets. The problem for me has been the thudding that drops on the fur make.

 

Exactly my experience. A good solution is a rainshield made of “hogs hair” air 
conditioning filter material. That stops the plops.

2a. quick question

Hello everyone,

finally have some money to invest in some high-end mics for "special 
moments" :)
Since low-noise and high reliability are my biggest concern, I came to 
comparing Audiotechnica AT-4022 vs. Sennheiser MKH 8020.
Based on experience of other field recordists AT-4022 seems to be 
slightly less noisy and MKH 8020 has nicer sound.
Also, I heard about some issues with 8020 breaking, so that is a bit 
scary - to have a mics worth 2.4k euros, which cannot be trusted.
Anyone has any input on the matter?

Thank you,

Jonas

Jonas, 

Choosing mics is never a quick question. :-) 

My own choice still is one or two MKH 416's. I've got several used ones and 
for stereo you can afford to buy three and have one spare rather than pay 
full price for one new one. 

Why are you looking at omnis? You can of course add a fig-8 for stereo but 
you will have full sensitivity for noise from every angle, including up and 
down (ground reflections). This also applies if you add a fig-8 for stereo - 
and stereo is a much more attractive option with wildlife. 

The next best is a cardioid which can be used in pairs for a wide but good 
clean stereo image with reduced sensitivity from the sky and the rear which 
is important for nature recording. Unless of course if you record far from 
aircraft routes and wind in trees above you. 

For mono recording, a cardioid will give better discrimination and a quieter 
natural background, but nowhere as good as a 416 or a similar gunmic. 

With any quality mic, it takes a reasonably quiet natural background level 
to hear the mic noise. I'm not saying noise isn't important, just 
questioning whether it is worth an extra zero on the cost for the odd dB or 
so. 

If you use a parabola, this give a substantial lift in level so mic noise is 
much less of a problem. In this case a cardioid facing inwards gives the 
cleanest spectrum, but the overall frequency response is not flat, so a half 
decent mic should be fine rather than spending three zeroes.

These are both excellent mics, but only one is “high end.” I’d say the 4022s 
are best buys for economy, and the 8020s a serious investment that you won’t 
regret.

I think the 8020s will hold up better after long-term exposure to humidity; my 
3032s (same capsule) started having episodes of pops after a couple of years 
being left out overnight on expeditions. I’m keeping them with dessicant now 
but since I use them for backup I don’t know if that has solved it.

Since you’ve mentioned omni mics I’m assuming you want to record soundscapes 
rather than catch individual species.

Regarding omnis v. directional mics, there are many “right” ways to do it. It’s 
a matter of style. Spaced omnis, Jecklin disk, SASS, ORTF, MS, Soundfield…all 
make beautiful nature recordings.

In motion picture and television production, you’ve go to get it whatever the 
conditions. Directionality is essential for that craft. I’m in the omni camp 
myself; it doesn’t matter to me whether the jet is lower thanks to a 
directional mic, it’s still there. I document the anthropophony, and edit out 
the clean parts for aesthetic productions.

There were issues with manufacturing defects in MKH 8020s. I bought four, and 
one developed low level noises. In early 2014 Sennheiser hadn’t trained the US 
service shop in how to do the fix, so they all had to go back to Germany for 
factory rework. Since their return March 2014 they have been perfect.

A bonus of the 8020s is they go up to 50K; with higher sample rates you can 
catch wildlife that’s making sounds up there.

You’re welcome, Dan

Thank you for sharing. I am actually the guy who runs the campaign. I really 
like how it turned out :) Jonas

4a. Cable and Windscreen for AT822?
    Posted by: "Jim Mooney"  jmooney776
    Date: Mon Aug 3, 2015 5:51 pm ((PDT))

Hello All,

Been lurking for a bit and enjoying all the discussions.  I recently acquired a 
AT822 at a great price but it does not come with a cable or windscreen.  I 
would really appreciate any recommendations for a cable to interface it to my 
Olympus LS-10 and a decent windscreen for it as well.  

I’m new to field recording and just getting the hang of things and want to 
record mostly ambient sounds (ocean, woodlands, etc) to capture a sense of the 
place I’m in.   

Thank you all in advance for your help!

Best,

Jim

Hi Jim,

I have the later version AT8022 which I bought secondhand, also without cable. 
I can't remember the reason why; it might have been cost or unavailability, but 
I ended up making my own cable. I can only say that if I was in the same 
situation today I'd find a professional cable maker and pay him to do it! I 
don't know if you're in the UK or States, if you're in the States you might 
find it easier to buy an already made up cable, but here in the UK I seem to 
recall it was a problem.

I was fortunate that my unit came complete with original wind hairy in new 
condition and it works very well.

I've just realised I didn't say that I also bought mine to use with my LS-10.

I'm sorry I couldn't be of more help, but I wish you good luck with your 
recording

Cheers

Max
