Product Description
The noise barrier is a specialized acoustic baffle placed between the noise source and the receiving point, designed to block or attenuate the propagation of traffic noise and thereby reduce its impact on the acoustic environment of surrounding sensitive areas (e.g., residential districts, schools, etc.). Its core principle lies in inserting an obstruction into the sound transmission path, forcing sound waves to undergo reflection, transmission, and diffraction, thereby creating an “acoustic shadow zone” at the receiving point and achieving significant noise reduction.
