Noise Attenuation in Green Building
A Green Home Is Reasonably Quiet
|When building a green home, it is important to thecomfort of its inhabitants to control noise. Suggestions for controlling noisein a green home follow. Note that many of these suggestions useenergy-efficiency products or building tactics for energy-efficiency that alsoserve as sound attenuators.
Noise comes from many places. Green builders mustanticipate and control them.
Airborne sounds travel through walls orfloor/ceiling assemblies and can stem from either human activities (loud voices,amplified sound systems, animal noise) or from mechanical noise within thebuilding systems such as HVAC systems, elevators, dish or clothes washingsystems, plumbing systems, or even trash compactors.
Environmental noise can be caused by a widevariety of sources such as transportation (highway, rail, aircraft), industrial,and recreational facilities (race tracks, ball parks, children’s outdoor playareas).
Environmental noise is normally controlledthorough the building envelope. The most important elements of noise abatementthrough design of the envelope include:
Products are available to dampen noise. Theycontrol noise through absorption. Examples would be wall boards with soundcontrol properties, foam insulation, suspended ceilings, floor coverings,curtains, furniture, and partitions with absorptive properties.
Building a continuous barrier to trap or stop airmovement can greatly reduce airborne sound transmission. Foam insulation aroundplumbing pipes or seals around doors are examples of ways to eliminate airbornesound,. The effectiveness of this form of noise control is reduced when thereare breaks in the barriers such openings under doorways or even theinnocent-seeming in can lights and power outlets.
Interior and exterior walls, ceilings, floors, all allow sound to travel betweenand through them. Green home designs such as staggering openings of windows anddoors help block noise. Other design controls are placing noisy rooms (kitchenor play room) away from quiet rooms (study and bedrooms), using buffer zones(hallways or closets) to separate noisier areas of home from quieter areas, orplacing quiet rooms further from outside noise sources such as traffic oroutdoor play areas.
Isolate noise by confining it to the areas whereit originates when possible. Insulation usually helps control noisetransmission.
In multiple-story homes, overhead noise is a problem. Examples of overhead noisecontrol include, floating and hollow floors, floor coverings, stairs, andlandings.
HVAC systems generate noise that can be transmitted intothe home. Examples include:
1. Breakout noise.
2. Excess fan noise transmitted down the ductwork.
3. Drumming of duct walls,.
4. Regenerated noise in ducts at elbows, dampers, and diffusers.
5. Vibration transmitted from blowers.
Vibration control refers to any mechanism thatreduces vibration at the source, along the vibration path, or at the receiverlocation.
