Garden: watch out for ticks!
For better acoustic insulation of the garden, in order to be able to settle down quietly in a deckchair or have lunch in the middle of your plantations, several installations can be envisaged without distorting the space.
How to insulate your garden from noise?
There are many solutions to act as an acoustic screen.
The
brick
or
concrete
wall has the effect of bouncing the sound and sending it back outside.
If you already have a dividing wall, you can reinforce it with terracotta siding or with wood to create more consistent and thicker insulation.
But other solutions should be considered, such as solid
wood
or natural fiber walls, combined with mineral wool.
If you do not want to weigh down the decoration of your exterior, other possibilities, with more flexible materials, are available to you to attenuate the decibels.
You can also
create a slope

The
gabion
wall
has also proven itself, with stones that will reduce the noise around.

In recent years,
green screens
, relatively high panels (between 2 and 4 meters and a thickness at least equal to or greater than 20 centimeters) have appeared.
The plant screen is made up of a high, long panel with a braided willow or galvanized steel frame with wood, rock or mineral wool in the centre.
The set is completed by a substrate – choice of felt, sphagnum, earth or potting soil).
For a more aesthetic look, arrange evergreen trees, vines (ivy, wisteria, rosebush or vines) and flowers so that this block is less visually imposing.

The noise will not completely disappear, but certain sounds will be absorbed and reduced, there will be less echo and you will enjoy sounds that are more pleasant to hear, such as the chirping of birds pecking in your vegetable garden or the wind in the foliage.
Which plants to choose for a noise barrier?
To reduce noise pollution and promote a more serene environment, in an ecological and sustainable approach, plant anti-noise hedges are a good alternative.
A row of hedges, like a thick natural barrier, will slow down the wind, which carries disturbing sounds.

Dense plants and trees, such as cypress, bamboo, cedar, which resist the winter cold, can also be installed very close together and staggered.

How to install your noise barrier?

Before the installation, find out from your neighbors to find out if they are victims of the same problem as you and thus consider a grouped solution.
From a legal point of view, find out from your town hall about the town planning rules to be respected in terms of fences and hedges - such as the height of the wall - and from the co-ownership regulations if you are in a housing estate.
If you choose to install it yourself, a few factors should be studied beforehand, such as the sun exposure of your plants, wind resistance and suitable soil.
For the establishment of an embankment, the width of its base, to be effective and not to sag following a series of bad weather and over time, must be equal to at least twice the height.
A low-cost solution.
