Mechanical Noise Control


Noise and vibration from mechanical equipment impact every type of space.  The sources include HVAC noise that radiates off of the equipment casing, breaks out from ductwork, and permeates the room from supply and return air registers.  Mechanical equipment can be spread out across a ceiling plenum in commercial spaces, causing localized “hot spots” that disrupt meetings.  The equipment can be consolidated into rooms that, when not properly isolated from the adjacent spaces, can become noise epicenters for an entire floor.


Mechanical noise can also present itself in the form of vibration transmitted through a building’s structure.  Non-isolated machinery can set in motion walls, floors, and ceilings, which can radiate noise into a room, sometimes far away from the actual vibration source.  This is because a building’s structure can be a very efficient carrier of vibration.  Proper vibration isolation is essential in eliminating structure-borne noise.
