Abstract
A sound-absorbing noise barrier, more specifically to one comprising: a main body which has a front surface and a rear surface and extends horizontally and in which a space is formed between the front surface and the rear surface; and a sound-absorbing material which is accommodated in the space of the main body and is disposed at a distance away from the front surface and the rear surface respectively, wherein the front surface of the main body is formed with vertically oriented alternating projections and recesses and is formed with a plurality of sound-absorbing holes, and the overall cross-sectional area of the sound-absorbing holes is at least 20% of the cross-sectional area of the front surface. The sound-absorbing noise barrier of the present invention can be variously employed in construction and industrial products, has good sound-absorbing characteristics across a wide frequency range, and can present an aesthetically appealing external effect.
