What is Sound Absorption?
Sound absorption is the conversion of acoustic energy into heat when sound strikes a surface. Learn how absorption coefficients work, why they matter for room acoustics, and how to use them in design.
A Practical Guide to Acoustic Materials: Foam, Mineral Wool, Wood, and Everything In Between
Acoustic materials fall into three categories: absorbers, reflectors, and diffusers. Each type works differently at different frequencies. Here is a practical guide to selecting the right material for your room — with NRC values, octave-band data, cost ranges, and fire ratings for every major product type.
What Is NRC (Noise Reduction Coefficient) — The Number on Every Acoustic Panel Datasheet
NRC is a single number rating from 0.00 to 1.00 that describes how much sound a material absorbs. But NRC hides critical information about low-frequency performance. Here is what NRC means, how it is calculated, and why you need octave-band data for any serious acoustic design.
