Monitoring construction vibration Protecting sensitive spaces and equipment from interference. November 5, 2014 . Vibration mitigation. . if plywood screens are installed to protect the windows from flying objects, these also can be designed to provide additional sound attenuation.
General Principles of Sound Mitigation . The following four strategies can be used to reduce the transmission of sound: Add mass. Increase the mass of the wall or floor by using heavy, dense materials. Very massive, non-rigid materials, such as lead or sand, are ideal, but doubling or tripling the drywall is also helpful. Absorb sound.
Lynnwood Link Extension | Draft Environmental Impact Statement Noise and Vibration Technical Report i July 2013 Table of Contents Part 1: Noise
Noise from the compressors, condenser fans and even the supply and return fans can radiate through the casing and seep into the building. Buildings that do not have concrete roofs can experience higher noise levels because of the radiated noise. The problem is compounded if the roof top unit is placed directly on top of occupied spaces.
There are a number of contributing factors with system noise problems. Click underlined headings for more details below.. Fan Motor Noise - This is closely related to the fan wattage. (Use a quieter fan or wrap the fan) Fan induced vibration - This is due to improper fan blade balance. (Isolate piping from building components)

A noise barrier or acoustic shield reduces noise by interrupting the propagation of sound waves. With proper design and selection of material for the noise barrier or acoustic shield, noise reaching a noise sensitive receiver would be primarily through diffraction over the top of the barrier and around its ends.
