attenuation, fading (noun)

weakening in force or intensity

"attenuation in the volume of the sound"

attenuation (noun)

the property of something that has been weakened or reduced in thickness or density

attenuation (Noun)

A gradual diminishing in the strength of something.

attenuation (Noun)

A reduction in the level of some property with distance, especially the amplitude of a wave or the strength of a signal.

attenuation (Noun)

A weakening in the virulence of a pathogen or other microorganism.

attenuation (Noun)

The tapering of a leaf etc to a fine point.

attenuation (Noun)

A fabrication process in which a material is stretched out into a thin shape.

Attenuation

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.

Attenuation

In physics, attenuation (in some contexts, extinction) is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates. Hearing protectors help reduce acoustic flux from flowing into the ears. This phenomenon is called acoustic attenuation and is measured in decibels (dBs). In electrical engineering and telecommunications, attenuation affects the propagation of waves and signals in electrical circuits, in optical fibers, and in air. Electrical attenuators and optical attenuators are commonly manufactured components in this field.
