Acoustics

How do Rigitone® ceilings improve acoustic performance?

Experience Sound That Feels Right

Rigitone® delivers high‑performance acoustic comfort through precision‑engineered perforations and optimized acoustic absorption.

Rigitone® ceilings are designed to transform the acoustic quality of any space — from classrooms and meeting rooms to healthcare environments and cultural venues.

Acoustic benefits include:

High-performing absorption values thanks to engineered perforation patterns (round, square, random, alternated).
Improved speech intelligibility in learning environments, auditoriums and meeting rooms.
Reduced background noise in offices, reception halls and healthcare buildings.
Balanced acoustics across low, mid and high frequencies, supporting clear communication and user comfort.

Both straight‑edge and chamfered‑edge versions deliver certified acoustic performance:

Absorption classes range from C to A depending on pattern.
Acoustic values tested according to EN ISO 354 and EN ISO 11654.
Optimal performance when used with mineral wool (thickness depending on pattern).

Result: better concentration, reduced fatigue, and improved well‑being.

What Is Good Acoustic Comfort?

In a room with poor acoustic performance, sounds will reverberate constantly – creating an unpleasant and uncomfortable acoustic environment, due to the long reverberation time.

But with the acoustic performance of perforated gypsum, rooms benefit from a pleasant, comfortable atmosphere, ideal for productive workplaces, due to the optimum level of absorption and reflection.

What is reverberation time and why does it matter?

Have you ever wondered why some rooms sound crisp and clear, while others seem echoey and muddy?

The secret lies in a crucial acoustic property called reverberation time. In this interactive guide, we'll explore what reverberation time is, why it matters, and how it affects the sound in different spaces.

What is Reverberation Time?
Reverberation time, often abbreviated as RT60, is the time it takes for a sound to decay by 60 decibels after the source has stopped. It's measured in seconds and plays a vital role in how we perceive sound in any enclosed space.

Listen and Compare
To truly understand the impact of reverberation time, nothing beats hearing it for yourself. We've prepared three audio samples to demonstrate different reverberation times:

Reverberation Time: 0 Seconds

This sample represents an anechoic chamber or a completely "dead" room. Notice how the sound stops abruptly with no lingering echoes.

Reverberation Time: 0.5 Seconds

This moderate reverberation time is typical in well-designed living rooms or small auditoriums. It adds a pleasant spaciousness without muddying the sound.

Reverberation Time: 2 Seconds

This longer reverberation time is common in large halls or churches. While it can add grandeur to music, it may make speech less intelligible.

Why Reverberation Time Matters

The right reverberation time can:

Enhance musical performances
Improve speech clarity in lecture halls
Create a sense of intimacy or spaciousness in a room
Affect productivity in office spaces

Conversely, incorrect reverberation times can lead to:

Reduced speech intelligibility
Muddy or unclear music
Increased noise levels in open-plan offices
Fatigue and decreased concentration
