- The practical unit between 0 and 1 expressing the absorbing efficiency of a material. It
is determined experimentally.
- Ratio of Sabine absorption of a surface
to the area of the surface. Unit, metric sabin per square meter, often omitted.
With a{sub i} as the Sabine absorption coefficient of the ith
surface whose area is S{sub i}, the Sabine absorption attributed
to the surface is A{sub i} = S{sub i}a{sub
i}.

-
[dimensionless]; metric sabin/m* ---of a surface, in a specified frequency band,
the measure of the absorptive property of a material as approximated by the
method of Test Method C423. Ideally, the fraction of the randomly incident sound
power absorbed or otherwise not reflected.
