Isn’t there a more simple way of evaluating a product for noise absorption?

Yes. CertainTeed uses the International Standard for Classification of Sound Absorbers (EN ISO 11654). This standard evaluates products over a wide range of frequencies (200-5000 hertz). It rewards products for high levels of absorption across the entire range of frequencies and penalizes a product for any weak areas of absorption. Products are graded on their individual performance from “A to E” with “A” being the highest class.
