Measuring Viscosity via the Speed of Sound

Hello,

I am on the search for papers, books, etc. on how one can measure the viscosity of viscous materials via the speed of sound. I've searched for a while now and haven't been able to find much on this topic. Any help is greatly appreciated.

Well, have you searched our resources?

Here are a couple of links:

A Google search offered me some more results, but unfortunately behind paywalls.
Here's one for free:

I watched just yesterday a documentation, where scientists used sound waves to detect fungal infections in trees, i.e. they've measured differences within the material. However, I don't know whether your question involves solid bodies.

No I wasn't aware of that post.

Very interesting. More on the lines of viscoelastic materials and liquids are of interest.

You may be more successful if you look for correlation between viscosity and attenuation of sound. The speed of sound is not directly related to viscosity.
