53 Outline of Topics 1. Introduction 2. Noise Control at Source 3. Noise Control of Transmission Path 4. Protection at Receiver 5. Summary 53
54 Move the machinery to a new location, more distant from the area where quiet is required Provide vibration isolation to reduce the radiation from surface on which the machinery is mounted Use a partial enclosure around the machine Use a complete enclosure around the machine, or use a booth to house the operator when it is impractical to quiet the machine Reduce the leakage paths that permit noise to leak through openings in the enclosure Reduce impact forces Summary 54
55 Summary Apply vibration-damping materials to the housing of the machine Insert flexible connectors between the machine and conduit, cable, piping, or ductwork connected to it Use an inertia block, where appropriate Reduce or modify surfaces that radiate noise Reduce resonance effects in mechanical and acoustical systems Use sound-absorptive material Modify or replace noisy parts (gears, bearings etc.) Reduce unbalance in rotating systems 55
56 Summary Use ducts lined with sound-absorptive material Use wrapping or lagging on pipes or ducts to increase their sound insulation Reduce or eliminate aerodynamically generated noise 56
