- The unit of sound absorption. One square foot of open window has an absorption of 1 sabin.
- A measure of the acoustic absorptive characteristics of a material named after Professor W. C. Sabine. Open air is said to be 1 Sabin. Other materials have a coefficients between 0 (totally reflective) and 1 (totally absorptive). Charts listing these numbers are available and give the absorption coefficients at different frequencies. Source: Church Audio & Acoustics Glossary
