Just a quick one to add to the knowledge base on here. Here is an excel spread sheet containing values for various materials we have used in schools projects. It contains the Sound Reduction Indices for various materials along with Absorption Coefficients. I cant see a way to upload it on here, so I have put a direct link to it for the time being.

All the best
