A Sound Transmission Class (STC) rating measures how much sound (in decibels) is stopped by a partition, such as a window or wall. It's a way to tell whether one type of partition is better than another without having to take someone's word for it. The higher the number, the better. Why Is an STC Rating Important? An STC rating matters because it's not a subjective measurement. A specific method is used to calculate how much sound of various pitches passes through a partition. A brick wall will stop more sound than a paper wall – that's obvious. However, if you're unfamiliar with a certain type of material, such as the types of acrylic, it's less obvious. That's when STC ratings help. Which Materials Have Higher STC Ratings? Acoustic grade acrylic inserts have a lower STC rating than acoustic grade laminated glass. In other words, acrylic stops less sound from passing through than laminated glass. Why? Essentially, it depends on how dense the material is. The denser it is, the harder for sound waves to pass through.

However helpful this baseline may be, an STC of 45 would be insufficient for insulating things like townhouses and condos, due to the shared walls, floors, and ceilings. What does an STC rating of 50 mean? The International Building Code requires an STC of 50 for multi family construction, which is the point at which noise is reduced to a point that people generally feel like their homes are adequately insulated from noise. It is also the point at which respondents to surveys begin a drastic reduction in noise related complaints. With a Sound transmission class rating of 50, speech cannot be heard through the walls, and loud sounds are only faintly audible. Recommended STC Ratings
If you are unsure of what rating would work for your project, there are some standards you can go by in helping you to determine your target range. The National Research Council of Canada conducted research on the importance of sound insulation, and found that an effective STC rating of 55 is recommended, and 60+ is ideal, especially in rooms where there is going to be music related noise.

When it comes to selecting new windows for your home, there are a number of factors to consider – everything from the type of window and color to configurations and energy-efficiency. One factor that many homeowners forget is acoustics – the amount of sound their windows will let into their home. In most cases, a window's acoustical performance will not affect the appearance or efficiency of your home, but it will most certainly impact its overall comfort, and tranquility. Acoustical Rating Systems
To determine how much sound is transmitted through a window, manufacturers conduct testing to calculate ratings for two primary sound control systems – Sound Transmission Class (STC) and Outdoor/Indoor Transmission Class (OITC). STC is the oldest and most widely recognized sound control rating system in the window industry.

STC, or rather "sound transmission class" for those of you that paid attention in school, represents an integer rating of how effective a partition (say a building wall) attenuates airborne sounds. Widely considered a standard in the United States, since 1961, STC ratings have been applied to both residential and commercial construction alike as a way to measure the soundproofing ability of the following to reduce sound transmission between rooms: Ceilings Walls Doors Windows In more lay terms, an STC rating provides you with information on how much (or little) a structure will stop or reduce the transmission of sound to the other side.
