Re: GSBN:Re: STC of Straw bales
There is a chance that we will be doing a test here regarding the SB
acoustic insulation value. The test if executed will be in a test facillity
at the Eindhoven University normally used to test window frames so I expect
that the measured values will till how well the test facilty functions. I
am sure that a properly executed SB wall has excellent sound insulation
properties far exceeding normal brick walls. What are STC numbers? We don't
use this qualification here. BTW the test will incorporate a spectral

To my knowledge, no formal tests have been done to provide STC numbers at
various sound frequency levels (such as building engineers sometimes need).
We all know they're mighty quiet, and that it's hard to shout through a wall
to someone on the other side, but don't have the exact geek numbers as yet.
Or, if someone does, I would very much appreciate learning of it, as the
culmination of the EBNet test program aims to be a compilation of ALL
testing of ALL sorts done to date - by EBNet or by others.
