What are some Damping methods? Check ALL Items that apply.

Damping at point of impact: neoprene isolators, carpet, cork underlayment. Thicker is better.

Damping between a hard surface and a structural surface: Resilient underlayment.

Damping between the structural floor and ceiling below. Decoupling the ceiling from the structure with spring hangers/resilient channels

Insulation in ceiling cavity; address flanking

Check Items that are TRUE What are some ways of combating Plumbing Noise?

Do not install plumbing

Isolate toilet rooms in the building core

Provide back-to-back plumbing chases for toilet room fixtures

Three main qualities of a sound-isolating assembly:

Flanking, Structurally Continuous, Airtight

Flanking, Absorption, Massive

Massive, Airtight, Absorption

Airtight, Massive, Structurally Continuous

Airtight, Massive, Structurally Discontinuous

Published acoustic performance data, while helpful in making comparisons, is only a description of the performance of the wall or floor ceiling absent flanking.

True

False

What is Transmission Loss?

Quantifies the airborne-sound-insulating properties of building elements

Quantifies the airborne-sound-insulating properties of building elements and evaluates effectiveness of building design

A single number rating assigned to an assembly's ability to resist vibration

What is Sound Transmission Class (STC) Rating

A single number rating assigned to an assembly's ability to resist Noise Transmission.

A single number rating assigned to an assembly's ability to resist Reverberation.

A single number rating assigned to an assembly's ability to resist Vibration.

A single number rating assigned to an assembly's ability to resist a variety of Frequencies.

Check Items that are TRUE for Sound Transmission

STC must be measured (laboratory tested) for accuracy, rather than calculated

STC measures assemblies.

The higher an assembly's STC rating, the more effective the assembly is at preventing the sound transmission.

The typical range of STC numbers is between 30 and 70

STC is all about assemblies

What is the difference between NRC and the STC?

NRC is within a room, and is all about assemblies; STC is room to room, and is all about surfaces

NRC is within a room, and is all about surfaces; STC is room to room, and is all about assemblies

NRC is room to room, and is all about surfaces; STC is within a room, and is all about assemblies
