Abstract (en)

A noise silencer for construction equipment is used to minimize outward propagation of noises generated from an engine room (11). The noise silencer is mounted in air intake (18) and/or discharge openings (19) of an engine room, and includes a frame (12) mounted in the one of the air intake and discharge openings of the engine room, and noise damping members (15) fixed to the frame at uniform intervals, and each including a first member (13), which is disposed inside the engine room in a horizontal direction such that cooling air introduced from outside to inside of the engine room by operation of a cooling fan (20) smoothly flows, and a second member (14), which is integrally formed with the first member and is disposed outside the engine room so as to be inclined upwardly at a predetermined inclination.
