When considering certain limitations of noise barriers in general, noise barriers can best serve as a solution if they are planned before the actual building (which is today a quite rare case-scenario). In addition, when incorporating a noise barrier into an existing urban environment, researchers should take into account the "visual pleasantness" and economic feasibility of the noise barrier [12, 13].

As previously mentioned, a more modern approach to noise management would be the soundscape concept. The soundscape concept modifies and complements the assessment of noise and its effects on humans [14]. Soundscape includes all the
