Small scale soundproofing
« on: July 09, 2010, 03:39:56 PM »
Hi there, I am looking to build an enclosure for a digital slr camera to block as much noise as possible. The enclosure is a pelican case, which is basically just a lunchbox but thicker ABS plastic composite of some sort. I had picked up some cheap open cell foam off ebay, and while it worked decently enough, it doesn't quite as good a job as I need. I think the issue is that the foam is rather cheap stuff, and that I don't have some kind of barrier like neoprene or mlv. Then again I'm not an engineer so I have no idea!! What is the best way to have all sound dissipated inside this container? Something that can be cut or plucked to accommodate the camera without losing it's capabilities would be best.

You can use our SSP foam mat instead of the open cell foam you purchased...
Keep in mind that the noise your trying to reduce is mechanical therefore you will always hear a muffled version of the shutter clicking...the path will always be where the lens meets the actual hard case cover.
no such thing as 100% soundproof.

Randy, thank you for the reply. Would you reccomend either MLV or neoprene as a backing material with the use of SSP Foam mat? The camera enclosure looks like this:

[]=|

[] is the pelican case

= is a large pvc pipe with a lens filter (|) on the front of it. I would assume that using a silicone based sealant between the lens filter and piping will help reduce the transmission of noise outwards and back into the case. The goal is of course to silence as much as possible, and there is a decent amount of room inside the piping for a material lining. Currently I have injected latex foam to dampen the noise, while this was partially effective, the open cell foam I think is the real weakness. I can remove that latex with no issue, so if there's a thin product that will help dampen the reverbaration through this chamber, that would be best.

I appreciate your time and look forward to doing business with SSP.

Yes you can use the MLV as a backing as long as weight is not an issue.

I have had first hand experience with this type of project and through many efforts the click from the shutter is still audible. You will get a reduction but, I would not expect complete silence from the mechanics of the camera.
