If you want to know more about STC rating glass , you will be possibly planning a construction project, and it is possibly not a tool shed. STC ratings usually emerge in places where we want to keep sound in or out, such as a road facing exterior wall, sound studio, or a bedroom above the garage.

When people evaluate noise dampening panels and building materials for reduction of noise, they depend on STC rating of the product. By realizing this rating of materials, we understand how much sound will be blocked from going through those materials. It is specifically vital in commercial construction. The STC was first introduced in 1961 and has since become the standard single number metric to describe sound blocking materials.

People frequently interchange STC ratings and NRC in similar contexts, but they are a bit different rating systems. The STC rating is vital while trying to lessen the amount of sound leaving or entering ...
... a room. The STC rating is vital when you are trying to lessen the amount of sound leaving or entering a room. The NRC rating is vital when you are trying to lessen reverberation and enhance the sound quality in a room.

How to measure STC rating?

Calculating STC ratings can appear slightly tricky first, but it is not as complex as you may think. Deciding ratings for ceilings, walls and windows all happen in the same way. The first step in rating a product is to decide the loss of transmission of the material at different frequencies. Two rooms with measurement equipment are divided by the material, one designated as the source room, and the other as the receiving room. The sound pressure levels in both the rooms in respect to different one-third octave band frequencies. Each of the transmission loss value is plotted on the graph in respect to a standard set of STC streamlines, with the closet matching streamline deciding the STC rating of the material.

How can I enhance the STC rating?

The simplest way to enhance your rating is by adding mass to the walls to enhance the overall density of the walls. Adding insulation or air space within walls also hinders sound from passing through the walls. Filling the gaps with STC rated insulation will enhance the STC rating more.

Using what you have learned

Now that you know a bit about STC rating glass, and how they can soften the sound of your worlds, it is time to determine what that means to you. If you have any kind of noise problems, there are some pretty easy things you can do to take care of them. It all comes down to the noise source, and your own tolerance levels. You will never completely value just how irritating these things are until they are gone.
