durasjon

Durasjon is a term used to describe the length of time that something lasts. It denotes the temporal extent from the beginning to the end of an event, state, or process. Durasjon can be measured in standard time units such as seconds, minutes, or hours, but may also be described qualitatively as short or long. The concept is distinct from frequency or rate, and its precise meaning depends on the context in which it is used.

In music, durasjon refers to the length of a note, a rest, or a performance as a whole. Notation assigns specific durations to notes, and tempo and time signatures influence how long each duration sounds. In film, television, and multimedia, duration or running time indicates the total length of the work.

In linguistics and speech science, duration describes the length of sounds, syllables, or pauses, contributing to rhythm, prosody, and intelligibility. In cognitive psychology and philosophy, duration can refer to the perceived length of time, which may diverge from clock time due to attention, emotion, or contextual factors.

Measurement of durasjon relies on timing devices, clocks, or audio analysis tools, and may be exact or approximate depending on precision requirements. Some durations are fixed by design, such as a scheduled concert, while others are variable, such as the length of a conversation. The term is widely used across disciplines, with its precise interpretation shaped by context. See also time, tempo, and rhythm.
