dømmende

Dämmende is an adjective used in several Germanic languages, notably Swedish, Norwegian and German, to denote properties or actions that dampen, lessen or reduce energy, amplitude or intensity. The root concept is damping: energy dissipation that limits motion, sound, heat transfer, or signal strength. The spelling varies by language (dämpende/dämpfende in Swedish and German; dämmende is a less common form but used in some contexts).

Applications include mechanical damping in machines and structures, acoustic damping in rooms and devices, and thermal insulation that reduces heat transfer. Materials such as rubber, foam, and mineral wool act as dämmende substances by absorbing energy; devices like dampers and shock absorbers provide deliberate damping; active damping uses feedback control to counteract motion.

In electronics and signal processing, dampening reduces ringing or overshoot through filters, snubbers, or controlled impedance; in architecture, sound-dampening materials reduce reverberation. Dämmende properties are often described by a damping coefficient or damping ratio, and by the decay of oscillations over time. In physics, for example, the amplitude of harmonic motion in an underdamped system follows a decaying exponential form.
