Science and technology

Natural sciences

Sensitivity (physiology) In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be ma ...

, the ability of an organism or organ to respond to external stimuli ** Sensory processing sensitivity in humans * Sensitivity and specificity, statistical measures of the performance of binary classification tests * Allergic sensitivity, the strength of a reaction to an allergen * The inverse of resistance (ecology), the ability of populations to remain stable when subject to disturbance

Electronics

* Sensitivity (electronics), the minimum magnitude of input signal required to produce a specified output signal ** Sensitivity of a transducer, the relationship between input and output power ***

Sensitivity (electroacoustics) The sensitivity of an electronic device, such as a communications system receiver, or detection device, such as a PIN diode, is the minimum magnitude (mathematics), magnitude of input Signalling (telecommunication), signal required to produce a spec ...

Mathematics

Sensitivity (control systems) The controller parameters are typically matched to the process characteristics and since the process may change, it is important that the controller parameters are chosen in such a way that the closed loop system is not sensitive to variations in p ...

, variations in process dynamics and control systems * Sensitivity analysis, apportionment of the uncertainty in the output of a mathematical model among its inputs * Sensitivity and specificity, statistical measures of the performance of binary classification tests

Other uses in science and technology

* Sensitivity (explosives), the degree to which an explosive can be initiated by impact, heat or friction * Film speed, photographic film's sensitivity to light

Music

* "Sensitivity" (Shapeshifters song), the fourth single from music group Shapeshifters * "Sensitivity" (song), a song by rhythm and blues singer Ralph Tresvant

Other uses

Information sensitivity Information sensitivity is the control of access to information or knowledge that might result in loss of an advantage or level of security if disclosed to others. Loss, misuse, modification, or unauthorized access to sensitive information can ...

, a property of information that may result in damage if disclosed *

Price sensitivity A good's price elasticity of demand (E_d, PED) is a measure of how sensitive the quantity demanded is to its price. When the price rises, quantity demanded falls for almost any good, but it falls more for some than for others. The price elastici ...
