  Attenuation (or verb attenuate) may also refer to:
  
  * Attenuation (botany)
  * Attenuation (brewing), the percent of sugar converted to alcohol and carbon dioxide by the yeast in brewing
  * Attenuation coefficient, a basic quantity used in calculations of the penetration of materials by quantum particles or other energy beams
  * Mass attenuation coefficient, a measurement of how strongly a chemical species or substance absorbs or scatters light at a given wavelength, per unit mass
  * Regression attenuation or Regression dilution, a cause of statistical bias
  * The process of producing an attenuated vaccine by reducing the virulence of a pathogen
  * Attenuation constant, the real part of the propagation constant
