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
- Return loss, the ratio of the amplitude of the reflected wave to the amplitude of the incident wave
Round-trip loss in laser physics refers to energy lost due to scattering or absorption
Loss function, in statistics, a function representing the cost associated with an event
