Sound absorption

Reverberation, the echo of disturbing sound in a space? Sound absorption offers the solution. It improves acoustics and provides more peace in work and living environments. But how does it work exactly and which material should you choose? We are happy to explain it to you.

What is sound absorption?

Sound absorption focuses on reducing reverberation and echoes within a space. This is achieved by dampening sound waves using absorbing materials, such as sound-absorbing panels. These panels are applied to visible surfaces, such as walls and ceilings, to prevent disruptive reflections.

In technical applications, acoustic foam is often used, such as egg crate foam. Sound-absorbing material dampens sound waves and captures them, which improves the acoustics and reduces noise nuisance. Note: sound-absorbing panels do not improve insulation to other rooms, but they do ensure a pleasant sound quality in the room itself.

How does sound absorption work?

Sound absorption occurs when sound waves enter a porous material. The energy of these waves is converted into heat through friction and vibrations in the material, thereby dampening the sound instead of reflecting it.

The importance of sound absorption in different environments

Sound absorption plays an essential role in various environments.

By using the right sound-absorbing materials, you can ensure a more pleasant and functional acoustics in any environment.

Offices

In offices, it helps to dampen distracting noises, allowing employees to concentrate better and be more productive.

Living rooms

In living rooms, it contributes to a comfortable living environment by minimising echoes and reverberation.

Studios

For studios, sound absorption is essential to ensure clear sound quality and optimal recordings.

Industrial environments

In industrial environments, such as factories and workshops, sound absorption is just as important. Reducing noise from heavy machinery, compressors, or ventilation systems not only helps improve safety and communication but also reduces hearing damage among workers.

What is the difference between sound insulation and sound absorption?

Although sound insulation and sound absorption are often confused with each other, they each have their own function in improving acoustics.

Sound insulation prevents sound from moving from one room to another. This is particularly useful for keeping external noise out of a room or preventing sound from penetrating into adjacent spaces. Sound absorption, on the other hand, focuses on minimizing echoes and improving sound quality within a space by absorbing sound waves.

Together, these techniques provide a complete solution for sound control and contribute to a more comfortable and better-sounding environment.

Which material absorbs sound the best?

Choosing the right sound-absorbing material depends on the application and the specific acoustic challenges in a space. Here is an overview of the best materials for sound absorption and their properties:

Acoustic foam: This material is very effective at absorbing mid and high frequencies. It is lightweight, flexible, and easy to install. Acoustic foam is widely used in studios, home cinemas, enclosures, machinery, and office spaces due to its excellent performance against echoes and reverberation.

Polyester Wool: This durable material offers versatility and excellent sound absorption across a wide frequency range. Polyester wool is environmentally friendly, reusable, and suitable for use in both decorative panels and functional applications such as partition walls or ceiling panels.

Melamine foam: Known for its lightweight and fire-resistant properties, melamine foam is often used in industrial environments, offices, and public buildings. It works particularly well in spaces where safety and acoustics need to be combined.

Each material has unique properties that make it suitable for specific applications. By making the right choice in the type of material you use, you can significantly improve the sound quality and comfort in any space.
