Guest Vadim Trofymenko Posted January 15, 2013 Share Posted January 15, 2013 (edited) Have a camera which loves to SPEAK loud! Did a test today with a decibel meter, and I must admit that I was a little bit disappointed. Here are results: Loaded with 400' magazine and film: 70db right next to the camera. 42db 15 feet away. Loaded with 100' magazine and film: 56db right next to the camera. 41db 15 feet away. Tried to record a dialogue and see if I can remove noise in post = nope. Motor is very quite, noise is coming from the magazines and film. Any ideas on how to make a camera barney?

Brian Drysdale Posted January 15, 2013 Share Posted January 15, 2013 I don't know which camera you're using, but you can make a barney out of foam and plastic cloth. However, I don't think you'll reduce that noise figure by more than 6dbs. It sounds rather like it needs a blimp, which they used to make for cameras like the Arri 16ST. http://owyheesound.com/arriflex-16-blimp.php I once made a blimp for a Bolex using chipboard. It wasn't too bad, although it was pretty large - sort of a bit larger than 35mm sync camera size. Link to comment Share on other sites More sharing options...
Guest Vadim Trofymenko Posted January 15, 2013 Share Posted January 15, 2013 I need something lightweight that really works. Anybody tried using this self adhesive foam? Link to comment Share on other sites More sharing options...
Premium Member Adrian Sierkowski Posted January 15, 2013 Premium Member Share Posted January 15, 2013 One of the problems I think you'll find is that a good amount of noise is going to come out from where the lens is.. which just so happens to need a pretty clear path to form an image. This is why, on older cameras like the BLs, they blimped the lenses as well. I had a nice barney from Custom Upholster for my 2M which didn't make it that substantially quiet; but knocked her down enough to at least be able to get passable audio with camera noise you could-- in theory-- hide in the room-tone.

Guest Vadim Trofymenko Posted January 15, 2013 Share Posted January 15, 2013 Maybe there is some secret workflow I don't know about? Here is mine: Shoot on 16mm, shoot audio on tascam dr-40 with a shotgun mic, sync audio and video in Adobe system, output. Share yours. Link to comment Share on other sites More sharing options...
Zac Fettig Posted January 15, 2013 Share Posted January 15, 2013 You've got 2 choices. 1. Shoot on a blimped or self-blimped camera with a sync motor. Record sync sound. 2. Shoot MOS, and ADR it afterwards. Link to comment Share on other sites More sharing options...
Brian Drysdale Posted January 15, 2013 Share Posted January 15, 2013 I need something lightweight that really works. Anybody tried using this self adhesive foam? We also made a barney for a Bolex, however, you couldn't film too close. I'd go for the foam being at least 3cm thick, the foam for my Aaton's barney is at least one centimetre inside leather. I wouldn't consider anything less than that. . Link to comment Share on other sites More sharing options...
Jean-Louis Seguin Posted January 15, 2013 Share Posted January 15, 2013 A barney made of lead lined foam cuts down the noise considerably. It doesn't have to be that thick. Just google: "lead lined foam" for suppliers. Jean-Louis Link to comment Share on other sites More sharing options...
Brian Drysdale Posted January 15, 2013 Share Posted January 15, 2013 True, there are specialised acoustic products, they seem to be intended for cutting down engine noise, but might be worth checking out. Link to comment Share on other sites More sharing options...

Guest Vadim Trofymenko Posted January 15, 2013 Share Posted January 15, 2013 Those Acoustic Blankets seem good to me. Any thoughts? Link to comment Share on other sites More sharing options...
Brian Drysdale Posted January 15, 2013 Share Posted January 15, 2013 (edited) You could check out these products. http://www.noisekill...ng_products.asp I suspect the lead lined will be better at the lower frequencies, you really need to compare the specs or test the products.
