Living next to a busy road: dealing with traffic noise
Living next to a busy road can be convenient in terms of transport and services, but constant tyre roar and accelerating engines quickly become exhausting. According to the European Environment Agency, road traffic noise is one of the key environmental risks to health in cities (see reports on eea.europa.eu). The good news is that even in older buildings there are practical steps that noticeably reduce indoor noise.
Step 1. Identify where the noise comes from
In a flat facing a main road, noise usually enters through:
- leaky or old window frames;
- gaps between the frame and the wall;
- thin external walls and empty reveals around windows;
- open vents and service openings;
- un-glazed balconies that act like a sound funnel.
Keep a simple noise diary: note when it is loudest and what dominates — cars, trucks, motorbikes. This will help both when planning improvements and when contacting authorities.
Step 2. Get the most from windows and balconies
Proper glazing often has the biggest impact. Acoustics experts recommend looking not only at the number of panes but also at the thickness of glass and spacing between panes (see, for example, overviews by the Acoustical Society of America).
- Choose windows with an elevated airborne sound insulation index (Rw). Even a 5–7 dB improvement is clearly audible.
- Installation quality matters as much as the product: perimeter gaps must be sealed and covered.
- Glazed balconies or loggias create a buffer zone and can cut noise by several decibels.
Step 3. Use room layout strategically
Where possible:
- place bedrooms and children’s rooms on the quieter side of the building;
- use the loudest façade for a study, kitchen or living room;
- line external walls with wardrobes and bookcases to act as additional sound screens.
Step 4. Green barriers and courtyard design
Trees and shrubs are not magic, but when planted in bands and combined with earth berms they can soften noise and make it less harsh. Urban planning studies show that such combinations work better than isolated trees.
Talk to neighbours and the property manager about planting schemes or redesign of internal roads. Links to NoiseMap complaints and heatmaps help show that traffic noise is a real and chronic issue.
Step 5. NoiseMap and official measures
If traffic noise exceeds recommended limits, residents can ask for additional measures: noise barriers, speed reduction, restrictions on heavy vehicles at night. Internationally, guidance from the World Health Organization is often used as a reference.
- Add a point on NoiseMap describing the problem and attach photos.
- Send a collective letter to local authorities and road agencies, including a link to the map.
- Where necessary, request official noise measurements from public health bodies.
You may not be able to silence a busy road completely, but a mix of window upgrades, smart layout and outdoor measures can make a big difference indoors. NoiseMap helps you visualise the problem and track what changes once mitigation steps are taken.
