How to Select Acoustic Materials Based on NRC and Sound Frequency
Quick Summary: Choosing acoustic materials shouldn't come down to color swatches or texture samples alone. NRC ratings and frequency specific data tell you whether a product will actually solve your noise problem. This blog walks through how to read these numbers properly and use them to choose between options like acoustic spray paint, acoustic spray ceiling systems, and other treatments based on real performance, not just appearance. Introduction Walk into any conversation about acoustic materials, and you'll eventually run into NRC, the Noise Reduction Coefficient. It's the most commonly cited rating in the industry, and for good reason; it tells you how much sound a material absorbs. But relying on NRC alone, without understanding frequency, can still lead to disappointing results even when the number on the box looks impressive. This blog walks through how to actually use NRC and frequency data together to make smarter selections, whether you're comparing rigid...
