hljóðmiðlun
Hljóðmiðlun refers to the process by which sound travels from its source to a listener. This transmission typically occurs through a medium, most commonly air, but also water, solids, or even a vacuum in theoretical contexts, though sound requires a medium to propagate. The sound waves are generated by vibrations of an object, which then cause the particles in the surrounding medium to vibrate. These vibrations travel outwards as longitudinal waves, characterized by compressions and rarefactions.
The speed at which sound travels depends on the properties of the medium, including its density and
