Why a noise-reducing garden panel

In various scenarios a noise wall will be an excellent solution for your noise problem!


  • Road noise: is the first complaint of our customers! A road that becomes very busy over the years, with more and more traffic. Our SonoWalls, available in different heights, can muffle this almost constant source of noise and will reduce the noise in your garden or on your terrace.
  • Trains: Close to a railway, RER or tramway?  Our solutions reduce noise in the low frequencies of rail traffic!
  • Playgrounds: Basketball courts, skateparks, playgrounds with youngsters at play. A well-positioned noise barrier can give the residents of these facilities more peace and quiet.
  • Air conditioners: Heat pumps, air conditioners, cold units are an irritating source of noise often causing conflict in the neighbourhood. Our SonoWall Absorbers are particularly effective in the low frequencies by absorbing the buit in an enclosure to be mounted around noisy machines.
  • Neighbours: Neighbourhood noise is a source of irritation for many people. A SonoWall installed between 2 terraces or along the neighbor's pool will give you the peace and quiet you deserve.


Reduces noise by 50% !


The sound source produces waves and sound energy, which collide with the sound barrier.


Depending on the material used and the acoustic characteristics of the sound barrier, part of the direct source sound is reflected or absorbed, creating an acoustic shadow zone behind the barrier.


The sound emitted by the direct sound source remains above the acoustic shadow zone.  Any other sound is indirect or 'diffracted’.

The uniqueness of the SonoWall lies in the sound attenuation power obtained by the material in the core of the panel.

This traditional looking garden panel with acoustic core reduces the noise coming from a direct source (road, railway,...) by more than 50%.

SonoWall sound walls give you the peace and quiet you desire.

Configuration of a sound barrier

The effectiveness of a sound wall depends on a number of determining parameters : The distance between the sound source and the SonoWall (A), the height of the wall (B) and the desired acoustic shadow zone (C). In addition to this, possible indirect source noise from neighboring buildings or other obstacles must be taken into account.

Noise reduction panels: 

  • Different heights available. Depending on the situation, we recommend a certain height
  • The SonoWall panels are available in standard heights of 1m, 1m20 or 1m50 and are stacked for heights from 2m to 3m, and even higher if required.

Reflective and absorbent panels:

  • In the SonoWall range we have both sound-reflective panels and panels with one or both sides absorbing.
  • The application chosen depends on the situation, the topology of the terrain and the nature of the sound.

Posts, post sinkers and acoustic doors

SonoPost posts


Our SonoPost posts are specially designed for the SonoWall panels and are very durable.  They consist of 3 pieces with stainless steel screws and are autoclave class 4 treated.

There are different lengths available from 2,70m to 3,90m and this in 3 variants: intermediate, corner and end posts.


For the finishing we can provide cover slats that cover the panels and posts.


Stainless steel post sinkers

  • Inox sinkers for the installation of SonoPost posts on concrete
  • 10 mm thick
  • 5 anchor points




  • Our SonoDoor acoustic doors are available as complete kits.
  • Width 90 cm and height 197/215 cm



Installation of a sound wall

The SonoWall sound walls are easy to install, without complex techniques


  • Modular

The SonoWall elements are stacked to obtain the desired height. With elements of 1 m, 1m20 or 1m50 high and 1m83 long, different wall heights can be created.


  • Anchoring of the posts

Up to 3 m in height our wooden SonoPosts can be used and anchored in concrete foundations or installed with post anchors. For bigger heights of sound walls galvanized steel posts are recommended, the posts can be sealed in concrete or with concrete-anchor mechanisms.


  • Adaptable in length

The SonoWall panels can easily be shortened to obtain the perfect length of the required soundwall section. This is an advantage over metal cassettes that do not offer this flexibility.

Durable quality

Our panels are made of pine from northern Europe. This ensures a high wood density and a durable quality after autoclave treatment of the wood.

  • Acoustic core in Polyurethane, resistant to rot and durable
  • Autoclave treated class 3 and class 4 (for the posts in the ground)


Tested in an independent sound testing lab!

35dB RW: Surpassing noise reduction levels of some of the industrial sound barriers!


Our SonoWall Wood has performed very well in our independent Lab tests at the Eco-Scan Sound testing lab in Belgium. We have achieved a raw value of -35 decibels (dB) of sound reduction through reflection on our panels. It is generally accepted that to the ears of a normal person a sound reduction of -10dB is perceived as being half the sound level, so you can imagine how effective our Sonowalls are!

On the graph you see how our panels perform. Notice the 1Khz to 1.2Khz frequency band, this is the typical frequency of traffic noise where the results are at their best! This is tested according to the sound reduction index ISO 140-3.


Results shown according to ISO 717-1.
