[USMA:11953] SI equivalent of the sabine

[Karl G. Ruling]

Does anyone know the SI or metric equivalent of the sabine? The sabine is 
the unit of sound absorbtion of one square foot of a perfect sound absorber 
(an open window, e.g.). I can't find the sabine listed in IEEE/ASTM SI 10 
or in the NIST guide.
