<DIV dir=ltr align=left><SPAN class=828440703-12112010><FONT size=2 face=Arial>I
agree with Graeme.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=828440703-12112010><FONT size=2
face=Arial>A strawbale wall used internally would be a good sound
insulator. Rendered strawbale acts like a Helmholtz resonator! Similar to
the materials that are used for recording studios.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=828440703-12112010><FONT size=2 face=Arial>I
believe there has been some work done in The Netherlands - Rene Dalmeijer may
have some info??</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=828440703-12112010><FONT size=2 face=Arial>I
had some discussions a couple of years ago with him - but not sure where the
research was up to.</FONT></SPAN></DIV>

class=Apple-style-span>We've had an inquiry from a local road works company
about using straw bale as a landscape wall for acoustical reasons along the main
highway (keep in mind, in this neck of the woods...the main north-south road is
two lanes only...).</SPAN><SPAN style="FONT-SIZE: medium"
class=Apple-style-span><BR></SPAN><SPAN style="FONT-SIZE: medium"
class=Apple-style-span><BR></SPAN><SPAN style="FONT-SIZE: medium"
class=Apple-style-span>They have requested acoustical research and data.
We have the information in Bruce's book, but I thought I would check to
see if there has been any new testing or research done recently that you could
share with us?</SPAN><SPAN style="FONT-SIZE: medium"
