Hello All, 

I am wading through the Code requirements for four small row houses with straw bale walls between them.  We have the required fire rating tests in hand, but lack a test demonstrating the walls have an averaged  minimum sound transmission coefficient ( STC )  of 50. 

Arkin/Tilt sponsored a test for a project of theirs, and were surprised when the test wall didn't quite meet the minimum STC. 

Who'd'a thought a bale wall would not be isolative enough??

Does anyone know of other tests we can submit?
