External sound insulation
Noise nuisance from outside sounds is common. Think of traffic noise, a transformer or music. Sound insulation boards can in some cases limit the noise nuisance.
The sound insulation from outside to inside depends on various factors:
- What is the sound frequency?
- Is it impact sound or vibration sound?
- What is the current insulation of the building?
We offer a range of sound insulation boards that can contribute to reducing outside noise.
External sound insulation
Outside noise is noise from outside that bothers you inside. What you need to muffle this sound is strongly dependent on the sound. We distinguish the following sounds:
Low frequency sound
This sound has a very low humming noise. Usually this is felt as a vibration rather than an audible sound. This sound is caused by, for example, a transformer.
Low frequency sound brings your entire house into vibration. This cannot be solved by adjustments in your home itself. It must therefore be solved at the source. Call in an acoustic advisor for more information.
Impact sound
This is virtually the same as for low-frequency sound. Usually this sound is not continuously present. Impact noise can be caused by a passing tram, lorry or pile-driving, etc. Here too, it is difficult to do anything about it.
Airborne noise
Finally, there is airborne noise. This noise is caused by, for example, voices, road traffic, etc. By better insulating your home, this air noise can be limited.
To improve airborne noise, two things are important: a better gap sealing and a high insulation value. In many cases, airborne noise nuisance is the result of poor gap sealing or “deliberate cracks” such as ventilation openings. Cracks around window frames are also an important cause.
By sealing these gaps, most of the problem can be solved. For example, you can replace your existing ventilation with our Sonair. This acoustic ventilation unit has strong sound insulating properties.
The SonAir is also very suitable for ventilation on hot days; you do not have to leave your window open to ventilate (extra). This greatly reduces airborne noise.
If the gap sealing is in order, then the insulation value of the glass or wall is probably too low (e.g. with single glazing).
Before you take any steps in this situation, we advise you to hire an acoustic advisor so that you have a clear picture of the expected sound insulation.
