Definitions for "SABIN"
A unit of measure for sound absorption equivalent to one square foot of a perfectly absorptive surface.
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 beween 0 (totally reflective) and 1 (totally absorbtive). Charts listing these numbers are available and give the absorbtion coefficients at different frequencies.
a non-metric unit of sound absorption used in acoustical engineering. One sabin is the sound absorption of one square foot of a perfectly absorbing surface--such as an open window! The sound absorption of a wall or some other surface is the area of the surface, in square feet, multiplied by a coefficient which depends on the material of the surface and also on the frequency of the sound. These coefficients are carefully measured and tabulated. The unit honors Wallace Sabine (1868-1919), a Harvard University professor who founded the systematic study of acoustics about 1895. Sabine used this unit, which he called the open window unit (owu), as early as 1911.
