Helmet cams: How to avoid wind noise?

<em>Steve Outing</em>'s picture
By Steve Outing on 6/7/2006

Since we just added video to YourMTB.com -- and Walker's been posting some of his video clips on his blog for a while -- I have a question about helmet cams:

Does anyone know of effective ways to limit or eliminate wind noise? On most of the helmet-cam video I've seen where sound is included, you not only heard the rider's heavy breathing, but also on downhills the rather loud sound of wind on the camera's microphone.

Any tips for avoiding this?

Edit, edit, edit! I think that's the answer to your question. I guess a lot of cameras come with editing software. The one I use comes with Ulead. Mac's come with Imovie. I'm sure there are more advanced programs that could work as well.

The other option: turn off the microphone?

Ever see what they use in filming movies and such outside? The microphone has a great big sponge/fur over it. See, you're not hearing the wind per se, you're actually hearing the whistling of the air across the microphone holes. You need to cover those holes with something to dissipate the wind. Either hook up an external mic and put it somewhere that wind doesn't reach it, or cover the internal mic with sponge or thick, porous cloth. You may have to duct-tape it in place. Make sure it's sturdy, or you'll hear it flopping.

Do you think Duct Tape would work?

Yup, a winscreen...

I would say your best bet is to cover the mic with 1/4" foam from a craft or home improvement store. I am having the same problem, and I have some foam laying around so Ill try it out.

yup.. foam is what is used.... the faster the speed the more you need! most of the time in bike videos you really don't want to have sound anyway. so unplug/shut it off.

hey where do you get a helmet cam by the way? how much? I do some small time 3D animations and videos for a recording studio... might be fun to add a music video to a bike scene...?

Your best bet is probably the foam, you will probably nee a piece about an inch thick. Your other option, is to put the video to cool music and slow down some of the really sewwt shots.

I have the windscreen on my mic and hook the mic to my backpack so it is behind me. That has worked well for me.

I got my camera from www.helmetcamera.com There is also Viosport but they have the mic built in to the camera so I am not sure how that one works as far as wind noise.
