riktningsverkan
Riktningsverkan, a Swedish term, translates to directional effect or directional influence. It is primarily used in the context of acoustics and audio engineering to describe how sound waves propagate and how the perceived loudness or clarity of a sound changes depending on the listener's position relative to the sound source. This phenomenon is influenced by several factors, including the frequency of the sound, the size and shape of the sound source, and the presence of obstacles or reflective surfaces in the environment.
Higher frequency sounds, due to their shorter wavelengths, tend to exhibit a more pronounced directional effect.
The design of loudspeakers is a practical application of riktningsverkan. Tweeters, responsible for high frequencies, are
