View Full Version : Help! How can I get rid of wind noise in SR11.
Mike Burgess April 16th, 2008, 01:03 PM I have the SR11 and really like it except for windy days. The mic picks up wind noise (distortions) very easily, and it is loud. On a windy day, there doesn't seem to be any way to eliminate the damn wind from ruining your shot.
I have tried a wrist band wrapped around the front quarter of the cam covering the mics, but all that does is eliminate some the higher frequency sounds. It does nothing for reducing the sound of the wind disturbances in the mic; they are just as loud and frequent as without the wrist band.
Suggestions? I would like to know if anyone has tried to tackle this problem and found a real, workable solution.
Thanks.
Mike
Ken Ross April 16th, 2008, 01:56 PM Mike, typically a wind filter on cams like this do exactly what you noted. They will reduce the noise somewhat, but with it go the higher frequencies.
Dave Rosky April 16th, 2008, 03:10 PM Mike, maybe there's a do-it-yourself solution. Maybe you could get some acoustic foam from Radio Shack, like the type used to make wind noise reducers for normal microphones, cut out an appropriate sized piece, then judiciously apply a few very small pieces of velcro (the hook side) to the camera at a few points around the microphone area and apply the filter. Unlike the wristband, the acoustic mic foam should help reduce wind noise without appreciably attenuating the normal high frequency sounds.
I have no idea if this would work well, but it seems like something that would be cheap to try. You might even be able to test the idea out first using masking tape before attaching pieces of velcro to the camera.
Like Ken said, though, it's unlikely you'll be able to eliminate all the noise on windy days.
Mike Burgess April 16th, 2008, 04:36 PM Dave, how would you attach the velcro strips? Glue? It seems like I would have to apply the velcro completely around the microphone, lest wind works it way under the foam, making the whole thing unusable.
It is something to think about, thanks.
Whatever I do, I don't want to screw up, or mar up the cam and then possibly having to remove the material due to it not working very well.
Ken. Yes, the higher frequencies reduced, I can understand. I could even live with that if the wind noise were even somewhat reduced. But that was not the case. The wind seemed pretty much just as annoying as without the wrist band.
Any one else who has tried things, or who have any inexpensive ideas, please chime in.
Thanks.

Dave Blackhurst April 16th, 2008, 06:45 PM Hi Mike -
Haven't tried it, but I may have to experiment - shot some in wind and didn't notice a problem, but wasn't watching the audio enough to notice. Around here a breeze is where the birds fly backwards, wind is when the jackrabbits fly backwards...
They have sticky back velcro - most hardware stores, fabric stores, and probably any general merchandise place ending in "mart" should have something in strips or squares and perhaps varying grades of sticky stuff on the backing. MOST of the sticky stuff can be peeled later, and while it might take a bit of cleanup, it shouldn't mar the camera. The surfaces involved are pretty smooth, but there may be some risk to the printing on removal...
Looks to me like there's plenty of room to put a strip all around, but the AiShoe door is right there, so you'll need a movable section I'd suppose. Probably go with the "hook" side on the camera, then perhaps some fabric backed fur might just attach with the backing acting as the "loop" - you could try various fashionable lengths, colors and materials, foam backing or not, etc, etc.
That's my take on it, may even have to fiddle with it now the question has come up - I know the CX7 mic was notoriously noisy in certain high wind conditions, like falling out of a moving aircraft, so the noise here is no doubt a potential issue. I'm guessing the trick is to create a "dead air" space atop the mic area without blocking too much sound transmission. Sounds like a fun bit of engineering!
Dave Rosky April 16th, 2008, 07:37 PM What I was originally thinking was that since the top of the camera is curved, that you might only need velcro on the sides, and then when you attach the foam (which presumably is flat), the curvature of the camera would hold it against the mic pretty well, but it would require some experimentation. Maybe you would need it all around to prevent air from blowing in under the foam.
As was said, you can get velcro that is sticky-backed and cut small strips of the hook side to attach, but depending on the brand, etc., it might stick pretty well. That's why I was suggesting to see if it's possible to first attach the foam with painter's masking tape, which by design is easy to remove without leaving any stickiness behind. Of course you would have to get the masking tape on in such a way that it blocks air from getting in under the foam.
It's kind of a shame the camera manufacturers don't provide something like this, they could sell it as an option that clips on nicely. I guess they just assume everyone will want to carry around an external mic (that they'd be happy to sell you ;-) )
Brian W. Smith April 17th, 2008, 07:09 AM Mike, typically a wind filter on cams like this do exactly what you noted. They will reduce the noise somewhat, but with it go the higher frequencies.
The windscreen option on my HG10 doesn't suffice.
The only options are Auto or Off.
It is really bad on 10+ mph days.
Guess I'll have to try some foam and velcro it as suggested here.
Mike Burgess April 19th, 2008, 09:30 AM Thanks to all who responded. Later this week I will try the velcro and foam solution, and report back as to how it performs.
Respectfully,
Mike
Tom Cadwalader October 22nd, 2008, 11:59 AM Did anyone try the velcro and foam trick for the wind noise?
thanks
Tom
Mike Burgess October 22nd, 2008, 12:57 PM Yes, I put a velcro base around the microphone area and attachted a cover of velcro attachtment type material plus a layer of fabric above it. Works fairly well; eliminates I would guess about 60-75% of the wind noise.
Mike
Tom Cadwalader October 22nd, 2008, 01:54 PM Thanks Mike, I'll have to give that a try on my SR11.
Larry Horwitz October 22nd, 2008, 06:43 PM Does anybody have any experience with other external microphones which could be used in windy situations to eliminate or greatly reduce the wind noise? I have the same issue with my two Canon HD camcorders, both of which allow external mic connections.
Thanks in advance for any suggestions.

Bruce Foreman April 18th, 2009, 12:43 AM I've had the Rode SVM for about 2 years now, it came with a "Deadcat" wind muff which helps tremendously. In most cases it completely eliminated wind noise and even in high gusty winds (one night doing a short film while a "blue norther" rolled in, only the strongest gusts caused much of a wind acraping across the mic noise while the rest just registered as the kind of wind you might add in foley.
The best solution of course is a blimp and several issues back Videomaker magazine had a DIY blimp article that looked workable.
Some have made their own "fur" windmuffs with fake fur from fabric shops. What works best is long hair "fur" and it usually needs to be combed and fluffed up before each use.
I recently got in a Rode VideoMic (the monaural shotgun type) and ordered a "Deadcat" with that one also. The Deadcat for the Rode SVM fits right over the metal screen of the mic where the Deadcat for the monaural shotgun Rode fits over the foam screen. The foam screen you see in pictures does no good outdoors. Seems good only for air conditioning "breeze" indoors.
Martyn Hull April 18th, 2009, 02:32 AM Bruce i have a rode stereo mic and find the stereo sound lovely, i use it on all my cams including my SR-12 and FX-7,how do you find the rode videomic in comparison, i know the videomic is mono but it reputedly is better for directional sound from farther away.
Bruce Foreman April 18th, 2009, 12:51 PM Martyn, I haven't had a chance to "wring" it out yet. Initial impressions are it isn't as "bright" and clear as the Rode SVM. Like you, I love the rich clean sound of the SVM and have had a client or two request I use my "good" mike on their projects.
I ordered the Videomic to have something with a bit of directional quality for working dialog in short films where I would need to have the dialog come in stronger than environmental sounds while still keeping some of the environmental "atmosphere". I understand that the Videomic works best close in and plan on stand and boom mounting it.
I've had good luck with the Rode SVM and a 16' extension cable and initial tests with the Videomic seem to indicate I'll be able to use it the same way. I think this Rode Videomic is way too huge to use on the size of camcorder I use (Canon HF100) and I plan to never use it mounted on the cam. For that kind of situation where I need to keep it light and simple, I have the Canon DM-100 and am very pleased with the way that worked on the first two projects using it.
Sorry I don't have a better answer to your question.
Martyn Hull April 19th, 2009, 01:29 AM Bruce i never realised the Videomic is as large as you say, the SVM is pretty big but i think you are saying you dont actualy use the SVM fitted on your cam, i just manage it fitted to my consumer cam but the muff neaded a trim.
Thanks for the reply.
Bruce Foreman April 19th, 2009, 04:45 PM Correct, Martyn. I tried the SVM mounted on a Panasonic PV GS500 ONCE. Even with a lens hood on the cam I got hairs hanging down in the field of view and had to reshoot footage using a Jones bracket to mount the SVM about 8" above the cam.
I shot one more project with the mic on the Jones bracket and from then on either stand mounted the mic close in to the talent, or stand and boom mounted it suspended above and about 2 feet in front of the talent. The effort has always been worth it as I get good audio this way.
The only mic I use mounted on the cam is the Canon DM-100 on Canon HF100's. This is a 2 pattern stereo and monaural shotgun mic with a well fitted Deadcat windmuff and I generally use it with the 90 degree stereo setting where it favors pickup from straight ahead with slight side rejection. One outdoor project I used it on was a military remembrance ceremony at Lackland AFB and the windmuff took care of killing breeze noise very well.
Where I want a lot of "ambient" audio along with dialog I will tend to use the Rode SVM in fairly close, I've had real good luck with that. The Rode Videomic is for where I need a little ambient audio but dominant dialog, again the tests I've seen indicate this mic is best used in as close as you can get it without it showing in the frame.
The DM-100 is for "lazy", when I don't want to have to keep up with stands and cords.
Hans Ledel May 4th, 2009, 01:57 PM Hi
I just bought the ”Stick-On fur windscreen” and tested it yesterday with my Sony SR11 and all I can say is.
This little thing really works.
I went to the top of one of the bridges here in Stockholm on a windy day and pointed the camera towards the wind and then went home to look and listen to the sound and guess what?
There was NO windnoise at all.
I could here my own voice clearly and the traffic as well and NO noise.
If I had done the same without the ”Stick-On fur windscreen” the sound would have been useless.
Now I can actually use my Sony SR11 on a windy day without bringing the Röde SVM every time.
This little piece of fur is just superb.
Cheers
Hans
Giles Moriarty May 5th, 2009, 12:17 PM Hello,
I have also just purchased a stick o 'windcutter'. It works very well and means I can actually use the original soundtrack to my movies (to date i had been removing the original track with the howling wind).
Pavel Houda May 5th, 2009, 02:58 PM Where did you guys purchased it from?
Dale McClelland May 5th, 2009, 03:25 PM A couple questions about this stick on fur windscreen:
1. When you ordered, did you specify the exact dimensions as they request, or did you just order it for the SR-11 and they knew what size? For my SR-11, I measure approx 15/16" by 15/16", although it is hard to be precise because my measuring tape only measures in 1/8" intervals.
2. Can the thing be removed and reattached multiple times, so you can use it only when needed. Or is it more or less permanently attached?
Thanks.
Hans Ledel May 5th, 2009, 11:35 PM Hi
1. I did measure as good as i could and I came to " 24mm X 24mm " and that worked really well
2.It "should" be permanenly attached and there is no reason to not have there all the time, it is just a small pieace of fur just "sitting" there over the mic.
You have to be very careful when you put it on so that it really covers the "mic area", so even if you could/can take it on and off , I would not do that
I hope this helps
Cheers
Hans
Dale McClelland May 6th, 2009, 08:53 AM That does help. I think I will order one and use your 24mm x24 mm measurement when I specify the size since that worked well for your SR11. Thanks.
J. Stephen McDonald May 9th, 2009, 02:31 AM The new Sony HX1 camera with HD video is known to have bad wind noise and of course, there's no input for an external mike. This might be a good solution.
John Gerard September 21st, 2009, 02:26 PM Hi,
I did a simular thing on my old Panasonic Palmsite camera. I just used 2 sided Scotch tape. It worked pretty well or me. I got the windscreen at a local camera store for $25us. A little pricey but then I knew it was the correct type of material. Then I cut it to size. I did not have a chance to test the camera in leavy wind before upgrading to a new Sony FX-7 so I can't comment on that part. This is a good way to test different configurations before perminantly attaching it with velcro.

J. Stephen McDonald September 21st, 2009, 05:06 PM This may be the mini windscreen that has been mentioned previously:
http://www.thewindcutter.com/shop/index.php?main_page=index&cPath=1_80
It comes with its own adhesive and is custom-cut by the manufacturer to match the dimensions you furnish about the size of the external mike opening. It costs $15. (U.S.). Most small camcorders or cameras would need just one, if the two openings are close together or might require two, if they are separated by too much space. I'd be inclined to give just one dimension, to span across the whole mike area. I haven't used one of these, so I can't comment about its effectiveness.
Randy Painter September 21st, 2009, 09:00 PM I tried the windcutter and it did not work for me. Shot a wedding with wind gusts of 25 mph and ruined the audio. Thank god the paster recorded it and I got to use that. Will be looking for an external mic for my SR11.
Ray Barber January 31st, 2010, 06:17 AM I've just received a big sheet of fur and backing from Rycote for under £15. I got it to make a muff for my HF S100 which is terrible in the wind. I'm still working on how it will fit becaue there's not a lot of space what with the manual control knob and ext. mic. socket. I think I might start by making a band out of knicker elastic and putting two pads of fur to cover the mics.
I reckon there's enough material to do this and make a couple of dead cats for my Rode Videomic. My wife is pretty handy with needle and thread, so I'm hoping I can sell one on Ebay and get my money back. :)
Erik Phairas February 7th, 2010, 09:09 PM Ha I got this. I use the SR11 as a helmet cam and to cut the wind I do this.
Put two pieces of masking tape on the mic in the shape of a V. With the open end of the V facing forward. Be sure to cover the sides of the mic. I find almost all the wind noises is coming from the sides. Try that.
Ray Barber February 8th, 2010, 04:11 AM My wife made up the windjammers. It took her age and made one hell of a mess. Seems the material is a pig to work with. Anyway, the one she made for the Rode Videomic looks great. The HF S100 was not so straightforward. We ended up with a thick ribbon that goes around the barrel and cut out holes where the mics are located. Then sewed a couple of rectangular pieces of furry stuff over the holes. It makes the camera look like an ageing guinea pig and it covers the manual control knob and the pop-up light.
I tested it with a hairdryer and it does cut down the noise through earphones. When I tried to record the results, all you could hear on playback was the hairdryer. I'll give it a try on a windy day and post the results.
