How To Soundproof Your Garden

There’s nothing more frustrating than a quiet or relaxing moment being interrupted by noise – whether it’s road traffic, nearby construction, a distant lawnmower or leaf blower or noisy neighbours. In fact, research from Churchill Home Insurance found that nearly half (44 per cent) of Brits have complained about the noise their neighbours make in the garden. But what can you do about it? One expert has shared their top tips for soundproofing your outdoor space.

To effectively soundproof your garden, you first need to understand where the majority of the noise comes from and what methods are most effective, explains Michael Wray of National Insulation Supplies. ‘Using materials and structures that absorb, block, or deflect sound waves are essential,’ he says.

Sound barriers can be broken down into two different types – natural and structural. Let’s start with the natural options first.

• Natural Sound Barriers

Hedges and shrubs

‘One of the most effective and aesthetically pleasing ways to add a natural sound barrier to your garden is by adding a dense hedge around the perimeter,’ says Michael. ‘Hedges, such as Leylandii, Laurel, or Privet are excellent for both sound absorption and privacy.’

Don’t forget to regularly trim them to make sure they stay healthy and remain dense enough to create that sound buffer.

Bamboo

For a quick, easy and affordable sound barrier, there’s bamboo. Not only does it grow quickly but it can get surprisingly dense, which is why it absorbs sound so well. However, Michael warns that it’s important to be ‘cautious with it and choose clumping varieties, as it’s invasive by nature’.

Trees

Now, trees are a great long-term option. ‘Planting trees like Evergreen Oak or Cypress can create a vertical barrier between you, your neighbours, and the outside world that helps in sound deflection,’ explains Michael.

You can also use trees strategically to cover any gaps that you might have in your garden, with the added benefit that it’ll provide privacy.

Fencing

As you might expect, fences can be one of the most obvious solutions when it comes to soundproofing your garden. They’re also relatively straightforward to install.

‘It’s best to opt for fences that are at least two metres high, and there are even acoustic fences available now specifically designed to reduce noise,’ says Michael. ‘They are constructed with overlapping panels and sound-absorbing materials, making them far more effective than your usual fences when it comes to blocking out noise.’

Walls

There are pros and cons to building a brick or stone wall in your garden. While it can be an excellent sound barrier, it may feel like you’ve blocked off a section or sacrificed your garden’s aesthetic appeal if you go down this route.

But for soundproofing, it’s a worthy option. ‘These materials are dense and can significantly reduce noise penetration,’ says Michael. To soften the overall appearance of the wall while adding another layer of soundproofing, you could utilise some climbing plants such as ivy or vines.

Acoustic panels

‘Installing acoustic panels is a more technical solution to this common problem, and they can be one of the most effective methods,’ Michael reveals. ‘These panels are designed to absorb sound and can be integrated into fences or standalone structures, giving you some choice when it comes to soundproofing and adding privacy.’

Garden sheds and outbuildings

And finally, if you’re thinking about investing in a garden shed, greenhouse or garden room, you can actually place them strategically to block sight-lines and absorb outside sounds.
