Sound insulation wall
What you need for the sound insulation wall depends on the sound problem.
- Airborne sound: Voice sound, Television sound
- Impact sound: Vibrations and thumping of construction by e.g. footsteps, closing doors, a vibrating washing machine.
Tips for improving the sound insulation wall:
– Sealing sound leaks: Seams, air ducts, ventilation and gaps around partition walls. Avoid gaps around intermediate door and window frames.
– You can reduce airborne and impact noise by using a sound-insulating front wall. This may not make contact with the ceiling, floor and structural wall. A so-called mass-spring principle.
– Damping sound at the source with sound absorption. Such as acoustic panels or plates. Think for example also of a rug to reduce contact sound with the floor.

Sound insulation wall
For a good sound insulation wall, it is important to determine whether you are dealing with contact noise or airborne noise. Impact sound in particular is difficult to solve.
At all times it is important to identify the source. And what is the weakest link in the sound insulation of the partition walls, ceiling and/or floor? You want to prevent expensive new partitions from being installed and the sound leak still appears to lie elsewhere.
Noise from neighbours
In order to reduce noise from neighbours in a good way, the walls in question should be made heavier. To clarify: If you double the mass of a wall, the sound transmission is reduced by about 3 dB.
In order to reduce walking noise from the upstairs neighbours, the floor itself should be tackled. Vibration insulation or a floating floor should then be installed for the upstairs neighbours.
Impact sound is a vibration that spreads throughout the construction. Once impact sound is present in the structure, it is difficult to attenuate it.
Examples of impact sound are slamming doors, footsteps, sound of drums and bass.
Solutions against impact sound
The only really good solution to counteract impact noise is to build a box-in-box. This is often not possible and also complex and expensive.
A frequently chosen solution is the installation of an additional wall. Ideally, this should be installed contact-free from the floor, ceiling and other walls.
A good pre-wall consists of spring bars, sound-insulating plates / absorption plates as filling (EASYpol polyester wool), and a double layer of plaster. However, there is a risk of flanking noise.
By flanking sound is meant a vibration (sound) that enters the room along other walls, floor and ceiling. This is therefore indirect noise nuisance via adjoining surfaces. To prevent this, another box-in-box is the best solution.
Airborne sound is sound that mainly propagates through the air such as voice, sound from a TV, etcetera. When airborne noise is noise, one or more of the following situations usually occur:
- The wall separating the house is very light (e.g. a brick wall).
- There are cracks in the house separating wall
When it comes to airborne noise, it is particularly important to check for cracks. These occur when the floor and ceiling are connected to the adjacent walls.
Here too, ventilation openings and/or heating pipes are weak spots. It is important to seal these gaps between the floor and other weak spots as much as possible.
In case of nuisance from airborne noise, a floating front wall is highly recommended. With a floating wall, very high sound insulation values are achieved for sound insulation walls. We offer a durable EASYpol polyester wool as cavity filling of the wall.
Make it negotiable
Before you take a measure against noise from neighbours, the most important thing is to make it negotiable. This is often the quickest, easiest and cheapest solution to prevent nuisance from noise from neighbours.
Be aware that noise nuisance occurs both to yourself and your neighbours. Sound goes both ways.
If you suffer from airborne noise from your neighbours, there is a good chance that they will also suffer from your voice. So you both benefit from good appointments and a good sound insulation wall.
