attenuation
n. uncountablen. the process of making something weaker or less strong. In science, it often describes how a signal or light gets weaker as it travels through a material.
n. the reduction in the strength or intensity of a signal, wave, or physical property as it passes through a medium. Often used in technical contexts to describe the loss of energy or power during transmission.
The signal suffered from high attenuation over the long cable.
Engineers must account for signal attenuation when designing the network to ensure data remains clear over long distances.
The study measured the attenuation of seismic waves as they passed through different layers of the Earth's crust, providing critical data for mapping geological structures.
From Middle English attenuacioun, a borrowing from Latin attenuātiō (“a diminishing”). Equivalent to attenuate + -ion.
