Also known as extinction
In physics, attenuation 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.

在物理学中，衰减（英語：attenuation或extinction）是指通量在介质中随着传播而逐渐损耗强度。例如阳光在穿过墨镜时衰减，X射线会在铅中衰减，光和声音会在水和空气当中以不同衰减率衰减。
