Sound Transmission Coefficient (STC) – otherwise known as “Sound Transmission Class” – is the golden standard that evaluates how well a barrier, …Reported STC values are found by doing transmission loss tests on a fully built assemblies in a lab. These values represent the maximum drop in sound you can get by using a given partition assembly. The following chart gives some qualitative intuition for what you can expect from different STC ratings. STC. What can be …Measuring sound transmission The amount of noise that a building element (such as a wall, floor, door or sheet of glass) is capable of stopping is expressed as a sound transmission class (STC) rating. The higher the STC number, the greater the noise reduction. For example, a wall with an STC rating of: 30 dB has little sound-control effectiveness The Sound Transmission Class is always reported as a whole number. STC is measured under laboratory conditions for a fully assembled partition. That means you won’t usually find STC ratings for individual components or products since STC is meant to be measured for fully constructed assemblies. The lowest STC numbers you see are around 33.

Mar 22, 2022 · Simply put, STC ratings measure sound level on one side of a wall, versus the other side of a wall.
