Acoustic Standards: ISO vs ASTM — Understanding the Difference

Definition ISO and ASTM are the two main families of acoustic standards used worldwide. They define how sound is measured, how single-number ratings are calculated, and how acoustic performance is rep...

Common Acoustic Engineering Mistakes

1. Confusing Absorption with Insulation The most common error is treating sound absorption ( NRC ) as sound insulation ( STC / Rw ). A highly absorptive panel reduces echo but does not block sound bet...

Acoustic Testing Services — What Should Be Tested?

Why Test? Acoustic testing verifies that a room or building element meets its performance target. It converts design intent into measured fact, and is the reliable way to diagnose problems and confirm...

Acoustic Design for Conference Rooms

The Goal A conference room must support clear speech and video calls. That means controlled reverberation ( RT60 ), low background noise, and adequate insulation from adjacent spaces (see absorption v...

Acoustic Design for Call Centers

The Challenge Call centers concentrate many simultaneous speakers in one space. Without treatment, speech from neighbouring agents intrudes on calls and raises the overall noise level, hurting both th...

HVAC and Mechanical Noise Control

The Problem HVAC and mechanical equipment generate noise and vibration that travel through air and structure. This noise is continuous and can dominate the background level in a room, harming comfort ...

Sound Insulation for Doors

Why Doors Matter A partition is only as good as its weakest element, and the door is often that element. A wall rated for high insulation is undermined by a hollow-core door with gaps — because even s...

Sound Insulation for Windows

Why Windows Matter Windows typically have lower sound insulation than the surrounding wall, so they often limit overall partition performance. Their insulation ( TL , STC / Rw ) depends on glazing, ai...

Sound Insulation for Walls and Partitions

What Determines Wall Insulation A wall's airborne sound insulation ( TL , rated as STC / Rw ) depends on the complete construction — not on a single material. The main factors are mass, number of laye...

How Sound Insulation Is Measured

Two Quantities, Two Tests Sound insulation has two parts: airborne sound (speech, music) and impact sound (footsteps). Each is measured separately. Airborne insulation yields Transmission Loss (TL) an...
