Summary: attenuation in Brief

'Attenuation' [əˌtɛnjuˈeɪʃən] refers to the weakening or reduction of something, such as signal strength or power. It can also refer to the reduction in amplitude of a signal as it travels through a medium or over a distance. Examples include the attenuation of sound, radio signals, and light. Phrases like 'attenuation coefficient' and 'attenuation correction' are used in specific technical contexts to describe measures and techniques for correcting or accounting for attenuation.
