STC is an extensively used rating of sound attenuation performance of floor systems and walls.

There are various aspects that impact STC ratings and it is vital to realize and strategise for these nuances. This post will explain STC ratings, what the testing implies, and the way to read the ratings.

What are STC ratings of materials?

In easier terms, the STC rating provides an indication of how a soundproof barrier might be.

How is STC rating determined?

STC ratings are determined through acoustic testing.

Details about STC testing

Using either acoustic absorption panels, an acoustic consultant will analyze the insulation, attenuation, or absorption of a system or material at 16 frequencies to ascertain how well it might work when installed.

Aspects that affect STC ratings

A single digit rating might not always tell the entire story. There are almost unlimited aspects in the field that will affect sound transmission, and many can’t be expected in laboratory testing.

For instance, buildings near any busy ...
... road or concert venue will generate a substantial amount of low frequency noise that could not be known when the assembly was tested.

Apart from that, construction methods, material attributes, and room acoustics will have an effect. Sound may be structure-borne and might pass through assemblies, like walls connected to subfloors and ceiling joists. This may enhance the sound level, but can’t be expected before the evaluation of the actual assembly.

Testing provides the best picture

While designing a space that will share ceilings, floors or walls, STC testing assists to meet client needs and code, and also avoid problems and arguments in office spaces.

While considering STC ratings, there is much to know and consider. There is much information out there readily available to us, but it is vital to get a complete picture of the situation. Keep reading to explore the things you never knew about STC ratings, and why they are crucial.

Frequency is important

In this noisy world, technology has created sounds that are off the STC charts. While a space might have a perfect STC rating, there will certainly be intrusive noises entering the room.

Owners and designers that have met code are frequently unhappy when complaints come in. There are various sound muffling strategies to facilitate these issues and this is where right communication about the usage of the space comes in.

Acoustic control is becoming extremely vital for human health, the ability to focus on vital chores, and handling stress. As building owners and architects identify the importance of environmental sound control, a realization and emphasis on acoustic ratings and solutions will be important. For manufacturers that can provide great acoustical products, the chance of growth is unlimited.
