• An event in which the team or individual in question did not win. Price in Economics and Business is the result of an exchange and from that trade we assign a numerical Monetary value to a good,
• 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

• Loss (film), a 2008 film by Maris Martinsons. In Baseball, a loss (denoted L) is charged to the Pitcher of the losing team who allows the run that gives the opposing team the lead with which In Physics, attenuation (in some context also called extinction) is the gradual loss in intensity of any kind of Flux through a medium In Waveguide design and construction angular misalignment loss is power loss caused by the deviation from optimum angular alignment of the axes of source-to-waveguide Bridging loss is the loss at a given Frequency, that results when an impedance is connected across a Transmission line. Coupling loss also known as connection loss is the loss that occurs when Energy is transferred from one circuit, circuit element or medium to another In Telecommunications, insertion loss is the decrease in transmitted signal power resulting from the insertion of a device in a Transmission line Path loss (or path attenuation) is the reduction in power density ( attenuation) of an Electromagnetic wave as it propagates through space In Telecommunication, free-space path loss ( FSPL) is the loss in Signal strength of an Electromagnetic wave that would result from a line-of-sight In Telecommunications, reflection loss occurs on a line which results in part of the energy being reflected back to the source In Telecommunications, return loss is a measure of power reflected from imperfections in an electrical or optical communications link Loss ( Lithuanian: Nereikalingi žmonės, literary "Unnecessary people" is a 2008 film directed co-written and co-produced by
