Random House Webster's College Dictionary
at•ten•u•a•tionəˌtɛn yuˈeɪ ʃən(n.)
the act of attenuating or the state of being attenuated.
the process by which a virus, bacterium, etc., changes under laboratory conditions to become harmless or less virulent.
Origin of attenuation:
1585–95; (< MF) < L
weakening in force or intensity
"attenuation in the volume of the sound"
the property of something that has been weakened or reduced in thickness or density
A gradual diminishing in the strength of something.
A reduction in the level of some property with distance, especially the amplitude of a wave or the strength of a signal.
A weakening in the virulence of a pathogen or other microorganism.
The tapering of a leaf etc to a fine point.
A fabrication process in which a material is stretched out into a thin shape.
Origin: From attenuatio
the act or process of making slender, or the state of being slender; emaciation
the act of attenuating; the act of making thin or less dense, or of rarefying, as fluids or gases
the process of weakening in intensity; diminution of virulence; as, the attenuation of virus
In physics, attenuation is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water. In electrical engineering and telecommunications, attenuation affects the propagation of waves and signals in electrical circuits, in optical fibers, as well as in air.
Dictionary of Military and Associated Terms
1. Decrease in intensity of a signal, beam, or wave as a result of absorption of energy and of scattering out of the path of a detector, but not including the reduction due to geometric spreading, i.e., the inverse square of distance effect. 2. In mine warfare, the reduction in intensity of an influence as distance from the source increases. 3. In camouflage and concealment, the process of making an object or surface less conspicuous by reducing its contrast to the surroundings and/or background. Also called tone down.
