Sound Masking vs Acoustic Panels: What's the Difference?

If you're researching ways to improve office acoustics, you've probably come across both sound masking and acoustic panels. Although they're often mentioned together, they solve different acoustic problems. Understanding the difference will help you choose the right solution for your workplace or, in many cases, recognise where a combination of both delivers the best result.

Acoustic panels are designed to absorb sound.

Installed on walls or ceilings, they reduce echo and reverberation by stopping sound reflecting around a room. That makes conversations clearer, improves overall acoustic comfort, and helps a space feel less noisy generally.

Acoustic panels are commonly used in:

• Meeting rooms
• Open-plan offices
• Breakout spaces
• Reception areas
• Collaboration zones

While they improve the quality of the acoustic environment, acoustic panels don't stop conversations from being overheard. They reduce reflected sound, not speech intelligibility.

Sound masking tackles a different challenge entirely: speech privacy.

Rather than absorbing sound, a sound masking system introduces a carefully engineered background sound that reduces how far conversations remain intelligible. People nearby can still communicate normally, but discussions become harder to follow as the distance increases.

This makes sound masking particularly effective wherever confidential conversations regularly take place, or where nearby discussions become a distraction. For a more detailed explanation, read our guide: What Is Sound Masking and How Does It Work?

The right choice comes down to what's actually causing the issue.

If an office feels echoey, or conversations sound harsh because of hard surfaces like glass, concrete or exposed ceilings, acoustic panels are usually the more effective fix. If the issue is conversations travelling too far, employees getting distracted by nearby discussions, or concerns about confidential information being overheard, sound masking is the better starting point.

Often, yes. Many workplaces experience both problems at once: an echoey room where conversations also carry too far. In that situation, acoustic panels and sound masking aren't competing solutions, they're complementary ones. Panels control the echo; masking controls how far speech travels once the room sounds right.

The best starting point is understanding what's actually causing the problem in your space before picking a solution, rather than assuming one technology will solve everything.
