Check Items that are TRUE of Brown Noise
Listening to brown noise will make you need to use the restroom
Brown Noise is a more bassy-y rumble
Brown Noise is inaudible to the human ear
White, Pink and Brown noise are like...
They do not mask other sounds because they amplify frequencies - creating a louder space
Act as background noise for corporate enviroments
Muffling Blankets of sound - they mask other sounds by making them less significant compared to the background
Instances of sound - they combine other sounds by making them into a hum
Check Items that are TRUE of Sound Masking (SM.)
Sound Masking is inserting a small amount of noise into the enviroment at a fairly low level
Sound Masking is inserting a large amount of noise into the enviroment at a high level
Sound Masking systems are useless as using accoustical construction works far better
Sound Masking systems make use of a special sound spectrum that drowns out speech, and sounds somewhat like a forced air HVAC system
Sound Masking can take some of the jarring sounds and smooth them out, and give you a more focuses concentration experience
Sound Masking uses white and pink noise
Sound Masking is generally more acceptable to humans than white or pink noise
Sound Masking does not smooth out sounds but instead uses frequencies to eradicate them
Check Items that are TRUE How can Architects reduce ducted fan noise?
Duct Baffles (silencers, attenuators), duct Insulation
High Velocity Air Delivery System
Low Velocity Air Delivery System
Place mechanical rooms far from sensitive areas
Use compact and tight mechanical rooms
Long straight duct runs
Convoluted duct runs
Choose quiet machinery
Where should vibration be addressed?
Inside the machinery
At the end route, where the sound enters the space
At the source
Spring isolators temper (BLANK) frequency vibration
Low
Medium
High
Compressed Neoprene Pads or glass fiber pads will temper (BLANK) frequency vibration
Low
Medium
High
Where should you locate vibrating equipment?
On the roof
In the center of the building
On grade
What is Impact Noise?
Impact noise relays the noise through the materials of a building
Impact noise sets a structure into vibration, with all the typical vibration results
Impact noise affects "Footfall"
What is the best remedy for Impact Noise?
Damping
Isolation
Acoustical Assemblies
Enclosure
Sound Masking
