Room acoustics
What causes sound reverberation in a room?
The acoustics of a room are significantly influenced by the shape and the surfaces of furnishings, ceiling, floor and walls. Reverberation occurs when sound waves are reflected by hard surfaces such as bare walls, floors and ceilings.Which materials reflect sound?
Highly reflective surfaces, as often used in modern architecture, cause long reverberation times, resulting in high noise levels and poor speech intelligibility.If you wish to improve room acoustics in your home or office, there are various solutions that you can conveniently order online at soniflex. By using the right sound absorbers, you can create a completely new (look and) feel to your interior spaces and a pleasant atmosphere. Our acoustic solutions based on high-performance acoustic materials will not only improve the sound characteristics of the room, but also allow you to add a stylish personal touch to its design and create a comfortable feel-good atmosphere. Special sound absorbers such as soni PICTURE acoustic posters, soni CUBE seating cubes and acoustic ceiling elements can help reduce reverberation in the room.
What does reverberation time mean?
The reverberation time tells you how long sound waves “reverberate” (are reflected back and forth) in a given room, which plays a key role in speech intelligibility.How do acoustic panels on walls and ceilings help optimize acoustics?
Acoustic panels on walls absorb sound waves and reduce reverberation, resulting in better sound quality and improved speech intelligibility. Optimized acoustic conditions are essential for a quieter and more pleasant environment that fosters both well-being and concentration.Where are acoustic wall panels used?
Acoustic panels on the wall are suitable for all kinds of rooms, such as living rooms, offices, schools, restaurants or music studios. They are ideal for dampening noise, and create a relaxed, productive atmosphere.What materials are acoustic panels made of?
Acoustic panels are made of sound-absorbing materials such as PUR foam, non-wovens or melamine foam. These materials are designed to effectively absorb sound waves and convert sound energy into heat.

The sound insulation board is ideal for retrofitting existing walls or ceilings with sound insulation – for example, by constructing a facing shell or cladding partition walls.
Tip for constructing a facing shell:
A facing shell is a very effective way of significantly improving wall insulation between neighbouring properties. Here's how to do it:
1. Attach battens:
Attach 30 mm or 50 mm thick wooden battens to the wall. Use our soni NBR sealing tape to insert an elastic layer between the wall and the battens. This prevents sound bridges.
2. Insert sound insulation boards:
Fill the gaps with soni 491 STL to achieve both sound insulation and sound absorption.
3. Attach cladding:
Screw plasterboard or chipboard onto the battens.
4. Decoupling & joint sealing:
Separate the construction from the floor, ceiling and adjacent walls with a small gap and seal the joints with acrylate for maximum insulation performance.
Tip: In our experience report ‘Neighbourhood / facing shell’, you will find a practical example of how soni 491 STL can significantly improve the sound insulation of a wall.
Alternative with visible surface: soni COMPOSITE

Improving room acoustics
If you want to improve the acoustics in a given room, you always need to consider the specific conditions there. Yet, the objective is always the same: Minimizing sound reverberation by means of sound-absorbing materials in order to reduce ambient noise and improve speech intelligibility. Our soundproofing products are perfect for various room types.
Sound insulation in the office
Whether in a small personal office or a large open-plan office, the reverberation time of sound waves should always be limited. For this purpose, we recommend the installation of sound-absorbing acoustic panels on the walls. Among our sound-absorbing products you are certain to find the one that will perfectly blend into the room’s design. When attenuated by the right acoustic materials, the sound of phone calls, conversations and other office noises will be perceived as much less disturbing by employees.
Room acoustics in the catering industry
Without the right sound absorbing materials, a restaurant, bar or café can quickly become unpleasantly noisy. Too much reverberation, a high noise level and poor speech intelligibility will make guests feel uncomfortable and even cause stress, if consciously perceived or not. By installing suitable sound absorbers on the ceiling and walls, you can significantly improve the room’s acoustics and ensure that excessive noise is optimally absorbed.
Room acoustics in indoor swimming pools
Many indoor swimming pools suffer from poor sound conditions and/or high noise levels because the absence of sound-absorbing materials allows the sound waves to be reflected back and forth by sound-hard surfaces. This results in poor room acoustics, which in turn negatively affects the well-being of the visitors. Why not cover (part of) the free surfaces with our soniflex absorbers in order to make the stay even more pleasant for your guests?
Room acoustics in a daycare center | kindergarten
Lots of children playing, laughing and telling each other stories - the noise level in a daycare center or kindergarten can be extremely high. However, it can be significantly reduced by installing different sound absorbers. Whether coloured circles or animals made of foam, our product range offers a wide range of options for optimizing room acoustics.
Room acoustics in your home
You want your home to be as quiet, cozy and relaxing as possible. After a stressful day at work, recharging your batteries is much easier in a living room or study that offers a pleasant acoustic situation. For each room type, soniflex proposes various products and options for equipping walls and/or ceilings with suitable acoustic materials.
Room acoustics in a waiting area
Whether at a doctor's or lawyer's office or in a bank, a waiting area is supposed to be quiet and comfortable. To help you make the waiting time for your clients a pleasant as possible, we at soniflex offer you suitable sound absorbers for the waiting area - always with the aim of creating an enjoyable, quiet atmosphere.
Room acoustics in a recording studio | rehearsal room
In a recording studio, the acoustic conditions play a particularly important role and are crucial for perfect sound. To ensure a successful recording that will provide the intended listening experience, we offer you a choice of suitable acoustic elements and absorbers for recording studios | rehearsal rooms to ensure perfect pitch and pure sound.
Room acoustics in a clubhouse
In a clubhouse, it can quickly get loud, so loud in fact that one can hardly keep up a conversation. Why not equip free wall spaces and other surfaces with effective (and stylish) sound absorbers and turn your clubhouse into a place where people like to spend time and socialize?
Optimize your rooms acoustically and add tasteful decorative touches at the same time.
