Impact Insulation Class (IIC) is its counterpart for impact noise from footsteps. Ask any property manager what generates the most noise complaints after residents move in, and it won't be voices through the wall. It's footsteps, scraping chairs, and dropped objects from the apartment overhead. IIC is supposed to predict that, and like STC, people misread it all the time.

While STC is a helpful shorthand, it is easy to misinterpret. Many complaints about walls "not working" stem from misunderstanding what the rating guarantees, and not from a faulty product.
Read MoreStructural vibration and vibration-induced noise are common challenges in modern building design and construction. These vibrations can come from everyday building systems—such as HVAC units, pumps, and other rotating machinery. They can also come from outdoor sources like nearby trains or heavy vehicles. But often, structural vibrations come from occupants themselves, in the form of footsteps and movement. While often unnoticed, they can manifest as subtle hums, stronger resonances, or even minor movements that impact how a building feels and functions.

The opposite occurs when an orchestra performs in a venue built for amplified concerts.
