The inventive concept relates to an acoustic barrier comprising a front wall, a rear wall, and two opposing and spaced apart side walls extending from the front wall to the rear wall. The compartment is at least surrounded by a front wall, a rear wall and a side wall. A channel is positioned spaced apart from the enclosed compartment, where the channel has: an inlet for enabling a portion of the proximity acoustic waves to enter and propagate through the channel; and an outlet through which the portion of the acoustic wave can exit the channel to interfere with an original portion of the acoustic wave propagating over the acoustic barrier. The inlet is located in the front wall and faces the noise source area. The outlet is located at a higher horizontal height than the inlet in the vertical direction, and is located at a rear portion of the front wall.
本发明构思涉及一种隔音屏障，包括前壁、后壁以及从前壁延伸到后壁的相对的且间隔开的两个侧壁。隔室至少由前壁、后壁和侧壁包围而成。通道定位成与围成的隔室间隔开，其中，通道具有：入口，用于使接近声波的一部分能进入并传播穿过通道；以及出口，声波的该部分能够穿过该出口而离开通道，从而与在隔音屏障上方传播的声波的原始的一部分发生干涉。入口位于前壁中并面向噪音源区域。出口在竖直方向上位于比入口更高的水平高度处，并且位于前壁的后部。
