Abstract
A noise silencer for construction equipment is used to minimize outward propagation of noises generated from an engine room. The noise silencer is mounted in air intake and/or discharge openings of an engine room, and includes a frame mounted in the one of the air intake and discharge openings of the engine room, and noise damping members fixed to the frame at uniform intervals, and each including a first member, 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 smoothly flows, and a second member, 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.
