Acoustic Diffusion vs Absorption: When to Scatter and When to Absorb
Learn the difference between acoustic diffusion and absorption, when to use QRD diffusers vs porous absorbers, and how to combine both for optimal room acoustics.
Sound Insulation vs Sound Absorption: Different Problems, Different Solutions
Understand why sound insulation (blocking noise between rooms) and sound absorption (controlling echo within a room) require completely different materials and strategies.
Acoustic Treatment vs Soundproofing: Why Most People Get This Wrong
The definitive explanation of the difference between acoustic treatment (controlling sound within a room) and soundproofing (blocking sound between rooms). Covers the mass law, decoupling, the 1% rule, STC vs NRC, and when you need each approach — with cost comparisons and worked examples.
What Is a Sabin? The Acoustic Absorption Unit Explained
A sabin is the unit of sound absorption equivalent to 1 square foot of perfectly absorptive surface. Learn how sabins relate to absorption coefficients, how to calculate total room absorption in sabins, and why thinking in sabins instead of alpha values prevents acoustic design failures.
