loss ' may refer to:

  • A negative difference between retail price and cost of production
  • An event in which the team or individual in question did not win.
  • Loss (baseball), a pitching statistic in baseball
  • Attenuation, a reduction in amplitude and intensity of a signal
  • In telecommunications, loss is a decrease in signal in a communications system:
    • Angular misalignment loss, power loss caused by the deviation from optimum angular alignment
    • Bridging loss, the loss that results when an impedance is connected across a transmission line
    • Coupling loss, the loss that occurs when energy is transferred from one circuit, optical device, or medium to another
    • Insertion loss, the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical fiber
    • Path loss, the attenuation undergone by an electromagnetic wave in transit from a transmitter to a receiver
      • Free-space path loss, the loss in signal strength that would result if all influences were sufficiently removed having no effect on its propagation
    • Reflection loss, a loss which causes energy to be reflected back toward its source
    • Return loss, the ratio of the amplitude of the reflected wave to the amplitude of the incident wave
  • in laser physics, loss (or background loss, or round-trip loss) may refer to the part of the energy of the optical field, that becomes unusable at each rond-trip in the cavity due to the scattering or absorption.
