STC Wall Rating Calculator: How to Calculate Sound Transmission Loss

Do you need to know how to calculate sound transmission loss? If so, you’ve come to the right place! In this blog post, we will discuss how to use the STC Wall Rating Calculator. This is a handy tool that helps you determine the sound transmission loss of a wall. It is important to understand how much noise your walls can block in order to create a quiet environment for your home or office. Let’s get started!

What is the STC rating?

The Sound Transmission Class (STC) is an integer rating of how well a building material absorbs sound. In the USA, it is common to measure the STC of a wall by mounting an STC meter on one side and playing white noise through a speaker on the other side while recording the sound levels with a microphones The STC value is then calculated from the resulting measurements.

There are many factors that contribute to a materials absorption of sound, but the two main properties are mass and stiffness. The more massive and stiffer the material, the better it will be at absorbing sound. For example, brick has a high mass and stiffness, so it has a high STC rating.

One way to increase the STC rating of a wall is to add more layers of material. For example, adding a layer of drywall will improve the STC rating of a wood frame wall. Another way to increase the STC rating is to use materials with high mass and stiffness, such as brick or concrete.

The STC rating of a wall can be increased by adding more layers of material or by using materials with high mass and stiffness. Adding a layer of drywall will improve the STC rating of a wood frame wall, for example. Using materials like brick or concrete will also increase the STC rating because they have high mass and stiffness. By taking these measures, you can improve the sound absorption of your wall and create a more peaceful environment.

Main factors impacting STC Wall Rating:

-DecibelsThe volume of a sound is measured using an acoustic measurement, which calculates the decibel level of a noise — the higher the decibel level, the louder the sound. A whisper has a decibel level of 30, whereas a rock concert may reach levels as high as 140.

 

-Frequency

Mass

-Stiffness

-Thickness

-Type of wall

Decibels, frequency, mass, stiffness, thickness, and type of wall are all important factors to consider when determining the sound absorption of a material. The more massive and stiffer the material, the better it will be at absorbing sound. For example, brick has a high mass and stiffness, so it has a high STC rating. Other important factors include the type of wall you’re working with and the thickness of your wall. By taking these measures into account, you can create a more peaceful environment in your home or office.

 

 

What is optimal value of STC Wall Rating?

There is no definitive answer to this question as it depends on the specific needs of each project. However, a higher STC rating will generally result in better sound absorption. Usually, an optimal value of STC Wall Rating is between 40 and 50.
