ducktape = dampening

[audioholic 5,000+ posts]

Ive never thought about it much, but I dont see duct tape having visceolastic properties that would make it an effective damping product. And even as a simple mass loader, its simply horribly inefficient. As said above, even man-juice could be considered a damping product if we are only discussing sticking properties, and *any* added weight. But within the confines of reality, duct tape serves virtually no purpose in the discussion of damping and/or mass loading. Taping off vibrating plastic interior panels? Sure, but that's not the topic here.

Vibration Damping

by By Ahid D. Nashif, David I. G. Jones, John Phillips Henderson

... as a result of many tests on the performance of multiple constrained layers, it has been found that most of the shear deformation occurs in the first damping layer, closest to the structure. In other words, all subsequent layers work mainly to increase the stiffness of the constraining layer to which the first damping layer is subjected.

and this assumes a viscoelastic adhesive. Duct tape doesn't have it and neither do marshmallows. If you use a viscoelastic adhesive to affix the marshmallow, the marshmallow becomes superfluous. Neither marshmallows nor duct tape are stiff enough to function as an extensional damper. In fact, neither of these techniques offer ANY meaningful reduction in amplitude. It's fine to play: How many angels can dance on the head of a pin? but it's irresponsible when unfounded speculation might lead people to waste their time and money on pointless pursuits.

Melt the marshmallows and stick them to the door. It will deaden the shit out of them. Never mind that they'll melt on hot days. I want my doors to be tasty, and my car to always smell like s'mores.

mmmm, s'mores. We haven't even considered how well graham crackers might work, let alone chocolate. Vibration damping may turn out to be Homer Simpson's dream job. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Brilliant. Use marshmallows to stick graham crackers to bare metal, then cover it in chocolate syrup. Tastiest sound deadening ever.

I actually like the marshmallow and graham cracker idea better than duct tape, but I dont have any links or scientific data to back that up.

It is not the best use of the product, nor is it efficient, but it will help to some degree, but it will also require TONS of it to make any difference,

That is layers and layers of funny.

Thanks.
