Effective through the placebo effect
It has now been proven that a hedge prevents a large proportion of street noise. Nevertheless, soundproof walls are of course much more effective. But would you like to look at a concrete wall from the kitchen window? Just through the greening, a hedge promotes your well-being and dampens the perception of annoying noises.

This is how you create the best conditions against street noise
The following aspects must be observed for optimal noise protection:
- suitable plants
- their growth
- the nature of the soil
Suitable plants
Plants with round leaves in particular keep outside noise. Have proven themselves ostensibly
- the evergreen ivy
- the wrinkled snowball
The growth
It is important that your hedge grows really tight. The noise still penetrates unhindered through gaps in the trunk area. A bit of physics is also involved: reliable noise protection is only provided if the leaves of the hedge grow perpendicular to the direction of the sound inflow.
The floor
Not only the foliage of a hedge is decisive for keeping the noise off. The nature of the soil under the plants is just as important. Uncovered ground or concrete slabs pass the noise on, whereas an area-wide ground cover acts like an additional protective shield. A lawn behind the hedge alone makes a significant contribution to soundproofing.
A hedge as a noise protection has many advantages
According to evaluations by the building authorities in various cities, the green hedges are becoming more and more common as property boundaries. And their popularity is well founded, because bushes and shrubs not only keep out street noise, but also
- are environmentally friendly
- bloom and smell wonderful in summer
- don't get rotten
- are constantly renewable
- provide a habitat for insects and birds
