Soundproofing Science Fair

I am conducting a soundproofing Science Fair project, but for the purposes of experimentation, is it appropriate to place the soundproofing materials between two layers of plywood? i.e. one little plywood box, soundproofing material, and then a larger plywood box?

Wood transmits sound 1200 times better than air, so is not a good soundproofing material.  The experiment could be placed like this: a box of Homasote (Builders supply) with a speaker in it, covered with our acoustical soundproofing mat.  Then another box over with a small hole in it with a microphone mounted on it's outside.  Acousical materials are then placed in front of the mike and inside the box to test their effectiveness.
