- Loss leader a deliberate commercial loss made in the expectation of recouping it by profitable sales of other lines
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
- 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

Famous quotes containing the words signal and/or loss:

“By day thy warning ringing bell to sound its notes,
By night thy silent signal lamps to swing.”
—Walt Whitman (1819–1892)

“... the loss of belief in future states is politically, though certainly not spiritually, the most significant distinction between our present period and the centuries before. And this loss is definite. For no matter how religious our world may turn again, or how much authentic faith still exists in it, or how deeply our moral values may be rooted in our religious systems, the fear of hell is no longer among the motives which would prevent or stimulate the actions of a majority.”
—Hannah Arendt (1906–1975)
