Acoustic Comfort: How Panels Impact Sound Insulation
Study on the impact of acoustic panels on noise levels in offices, restaurants and public spaces.
Excessive noise reduces productivity by 66% and increases stress levels. Acoustic panels are an effective solution for creating a comfortable environment.
The Problem of Noise in Modern Premises
The noise problem is particularly acute in open-plan offices, restaurants, shopping centres and educational institutions. High reverberation levels create a "buzz effect" which hampers communication and concentration.
Research shows that employees in noisy offices make 34% more errors and spend 20% more time on task completion.
How Acoustic Panels Work
Acoustic panels with perforations absorb sound waves and reduce reverberation levels. Perforation allows sound waves to penetrate inside the panel, where they are scattered and absorbed.
Types of Perforation:
- Round Perforation — classic option, effective for mid-frequencies
- Slotted Perforation — better absorbs low frequencies
- Micro-Perforation — visually discreet, suitable for design solutions
NRC Indicator — What Does It Mean
NRC (Noise Reduction Coefficient) — sound reduction coefficient from 0 to 1. The higher the value, the better the panel absorbs sound.
| NRC | Effectiveness | Application |
|---|---|---|
| 0.75-0.80 | Good | Offices, corridors |
| 0.80-0.90 | High | Conference rooms, restaurants |
| 0.90-0.95 | Excellent | Studios, theatres, cinemas |
Our GYPSUN Acoustic panels have NRC values from 0.75 to 0.95, ensuring effective sound absorption for various types of premises.
