Traffic noise annoyance: tips & tricks
We regularly receive inquiries about reducing traffic noise nuisance in the home. Is there something simple that can be done about it? And if so, what? Read it in our blog. When answering this question, we usually have good news and less good news. The good news is that there are indeed solutions to reduce noise from trains, (motor)ways, and airplanes in the home. The less good news is that these solutions are often more complex than simply sticking a single panel of insulation material.
How does sound insulation work?
The sound insulation value of a construction is largely determined by its mass and the sealing of existing gaps and openings. The sound insulation of a separating structure is as strong as its weakest link. An open door in a sound-insulating wall significantly undermines the sound insulation value.
Furthermore, a higher insulation value is achieved by increasing the mass. Every doubling of mass results in a reduction of 3 decibels. Knowing that an average brick wall is made up of 58 bricks weighing 2.5 kg each per square metre, this means an additional mass of 145 kg is required to achieve a reduction. The simple solution of sticking on a plate is therefore out of reach.
An effective solution is to install a stud wall that is completely vibration-free and placed in front of the structural wall using our resilient channels. Such a stud wall has a total thickness of 85 mm.
Are there "quick wins"?
Often yes. The significant sound leaks are often found in gaps around window frames and/or ventilation grilles. By initially addressing these sound leaks, a reduction can be achieved relatively easily:
- install a casing frame for the window frame;
- ensure that the seals around the frame are properly sealed;
- install a Sonair ventilation unit for fresh air and keep vents and sound boxes closed.
