Patent ID: 8544601

Claim:
A sound-absorbing noise barrier comprising: a main body including a front surface and a rear surface, the main body extending in a horizontal direction and having a space defined between the front surface and the rear surface; a sound-absorbing material received in the space of the main body and separated from the front surface and the rear surface and thereby separating the space of the main body into front and rear spaces, the sound-absorbing material being formed of a superfine fiber having a mass per unit area of 400 g/m 2 or more, the front surface of the main body being formed with recesses and projections in a vertical direction and formed with a plurality of sound-absorbing holes; at least one partition wall dividing the space defined between the sound-absorbing material and the rear surface into a plurality of rear partition regions, with each of the rear partition regions forming a Helmholtz resonator; and the partition wall is formed with a holding guide protruding therefrom to support the sound-absorbing material.
