## Sabin

a unit of the absorption of the energy of a diffuse sound field for a surface. A sabin is the absorption by 1 square foot of a surface that reflects none of the energy incident on it—that is, of a surface whose absorption coefficient is unity. The unit was named after the American acoustics specialist W. Sabine (1868–1919).

A simple example of a surface that reflects no sound is provided by an open window. If boundary effects are neglected, all the sound energy incident on the surface passes through it. For this reason, the sabin is sometimes called the open window unit, or OW unit. Other names used for the sabin are “absorption unit” and “square-foot unit of absorption.”

The absorption of a surface in sabins is determined by taking the sum of the products of the areas, in square feet, of homogeneous sections of the surface and the absorption coefficients of the sections.

The sabin is used in American and British works on architectural acoustics. In the USSR, the metric sabin is used. It represents the absorption by an open-window surface that is 1 square meter in area.

Sabins' funeral service was held Tuesday, April 2, at the Flint Funeral Home, 8 New York 95, Moira, N.Y.
At Spinal Restoration, Sabins will continue to build his executive team and expand the company's Clinical and Scientific Boards in order to begin the regulatory approval process for the company's products.
"Improving the quality of life through advancing medical technologies has always been a passion for me," said Sabins. "Spinal Restoration's technology is very elegant and exciting, and we have the opportunity to dramatically change the way back pain is managed, giving people a chance to restore the quality of their lives."
Sabins enjoyed gardening, camping and working on cars.
