Does the Thickness of Acoustic Panels Matter? Acoustic Panel Thickness, Absorption, and the Ideal Thickness for Better Acoustics
Yes, the thickness of acoustic panels matters. In general, thicker panels improve absorption, especially at lower frequencies, while thinner panels are more effective at mid and high frequencies. The best acoustic panel thickness depends on room type, installation method, material, and whether you want better speech clarity, music control, or broader sound absorption. Industry testing commonly uses ASTM C423 and reports performance with NRC values.
