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.
a unit of acoustic absorption equivalent to the absorption by a square foot of a surface that absorbs all incident sound
United States microbiologist (born in Poland) who developed the Sabin vaccine that is taken orally against poliomyelitis (born 1906)
a unit of acoustic absorption of one square foot of a perfect absorber
A unit of measure for sound absorption. 1 Sabin = the absorption of one square foot of a surface having 100% absorption e.g. an open window). See: Absorption Coefficient, Sabine.
A unit of sound absorption based on one square foot of material. Baffles are frequently described as providing X number of sabins of absorption based on the size of the panel tested through the standard range of 125 – 4000 Hz. The number of sabins developed by other acoustical materials are determined by the amount of material used and its absorption coefficients.
The unit for absorption of sound equal to the absorption provided by one square foot of a completely absorbing material, which is used to measure the ability of materials to absorb sound.
Measure of sound absorption of a surface, equivalent to 1 sq. ft. of a perfectly absorptive surface. Also see Sound Absorbing Unit.
The unit of measure used for sound absorption consisting of the number of square feet of sound absorbing material multiplied by the material absorption coefficient.
A unit of absorption having the dimensions of square feet or square meters, as appropriate. A quantity of the amount of absorption equal to the surface area (SA) of a material multiplied by its absorption coefficient (á).
The unit of acoustic absorption. One sabin is one square foot of perfect sound-absorbing material.
The Sabin is defined as a unit of sound absorption. One square meter of 100% absorbing material has a value of one metric Sabin. The unit is named in honor of Wallace Clement Sabine.
