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.
Read MoreSound Transmission Class (STC) is a number that architects, developers, and building owners use to predict whether a wall or floor will keep noise contained. 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 MoreOutdoor venues bring people together for the things communities love most, like sporting events, summer concerts, graduations, and festivals. But the same events that energize a crowd can generate sound that carries far beyond the property line.

Read MoreAs demand for data centers, oil & gas plants, and other energy facilities increases, we can assist in evaluating and recommending noise control solutions for these facilities. It is important to involve acoustical consultants early in the conditional use, design, and permitting processes.
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.
