How to Reduce Highway Noise in Backyard: Hush the Roar!

Ready to reclaim your backyard from the clutches of highway noise? This insightful article delves into innovative noise-reduction strategies that merge natural beauty with structural solutions.

Learn how to select the right vegetation and build effective barriers that not only reduce noise but also enhance your outdoor living space. From the science of soundproofing to practical tips for serene outdoor design, we’ve got you covered.

1. Planting Vegetation

So, let’s dive a bit deeper into our green allies in the quest for quiet. You see, it’s not just about popping a few plants in the ground and hoping for the best. The key here is density and diversity.

Dense vegetation, like the thick needles of evergreens or the wide leaves of broadleaf shrubs, naturally absorbs and diffuses sound waves. The fuller and lusher these green barriers are, the more sound they’ll catch.

Now, diversity. Why settle for one type of plant when you can have a whole ensemble? Layering different species with varying heights and densities creates a more intricate sound maze. Tall trees can catch the high-frequency sounds while lower shrubs tackle the lower frequencies. 

And strategic placement? That’s non-negotiable. Position your green troops along the property line nearest the noise source. Think of it as positioning your speakers for the perfect surround sound, only in this case, you’re configuring your plants to absorb the surround noise. This creates a green buffer zone, making your backyard feel like a secluded haven.

2. Building a Barrier

Building a physical barrier is like putting up a “Do Not Disturb” sign for unwanted noise.

Now, when we talk height, we’re not suggesting a towering fortress that blocks out the sun. But a barrier that’s at least 8 feet tall can make a significant dent in noise levels, because sound travels like light: it can spill over a barrier that’s too short.

And the material matters, too. Heavier materials like brick, stone, or concrete are like the bouncers outside a club, refusing to let the ruckus in. They’re dense, and they don’t mess around when it comes to blocking noise.

Now, if you’ve already got a wooden fence, it’s not all doom and gloom. Adding mass-loaded vinyl (MLV) sheets to your wooden fence can up its sound-blocking game without a complete overhaul.

Also, don’t forget the small details – gaps. Even small openings can let a surprising amount of noise through, much like how a tiny light can pierce through a dark room. Make sure your fence or wall is sealed tight from the ground up. Think of it as soundproofing: every seam, every joint matters.

3. Installing Acoustic Fences

Acoustic fences are like the special forces of sound barriers – they’re engineered specifically to deal with noise.

They work on two principles: absorption and reflection. Unlike your typical wooden picket fence, acoustic fences are designed with materials that absorb sound, preventing it from bouncing back into your space. And for sound that doesn’t get absorbed, the design of the fence will reflect it in a direction away from your backyard.

One of the key players in this field is MLV. It’s heavy (massive, really), flexible, and can be cut to size and attached to existing barriers.

It’s not the most beautiful thing to look at, so you might want to layer it with something more aesthetically pleasing. MLV can be sandwiched between a wooden fence and some kind of finishing material, like an attractive wood panel or even a green wall of ivy, for a combination of diffusion and absorption.

If you’re thinking about adding acoustic panels, you’re looking at a range of options from perforated metal to fiberglass. These panels can be mounted onto existing structures and are designed to not only block but also absorb sound, kind of like those fancy noise-canceling headphones.

4. Creating a Berm

Now let’s get our hands dirty and talk about berms. A berm is essentially a mound of earth. But not just any mound – think of it as a sculpture, one that curves and winds in a way that disrupts sound waves from the highway. Building a berm is kind of like shaping a mini hill in your backyard, a natural feature that’s both functional and stylish.

The serpent-like shape isn’t just for looks; it’s strategic. By curving the berm, you increase the surface area that deflects noise. And the height? You want to aim for a berm that’s tall enough to make a difference but still maintains the integrity of your landscape design. Typically, a few feet in height can work wonders if constructed correctly.

Now, to truly optimize your berm, you want to adorn it with a mix of plants. This is where your berm turns into a lush rampart. The plants not only add to the mass needed to block sound but also attract wildlife, adding a touch of nature’s symphony to mask the traffic noise.

5. Water Features

Moving on to the rhythmic sounds of water features. They work a bit like auditory alchemy, transforming the grating noise of the highway into a background score that’s actually soothing.

The trick here is placement. You want that water feature to be close to your favorite hangout spot in the backyard – maybe near the patio or beside your outdoor reading nook.

The sound of water is scientifically proven to be calming, so a fountain, a waterfall, or even a simple tabletop water feature can have a big impact. And the variety is endless – from zen-like trickle fountains to more dramatic cascades. Each has its own unique sound profile, which can mask different levels of highway noise.

6. Outdoor Sound Systems

And for the tech-savvy and sound-savvy, outdoor sound systems are the modern-day wizards of noise control. We’re not just blasting tunes to drown out the highway; we’re strategically deploying sound.

Outdoor speakers can be placed to create a blanket of white noise – that consistent, soft sound that can blend and neutralize the jarring noise of traffic.

It’s about creating an aural landscape, a soundscape that uses technology to your advantage. By selecting the right white noise – like the sound of a gentle rain, rustling leaves, or even ocean waves – and playing it through your outdoor sound system, you’re effectively putting up a sound barrier that’s invisible and ever so clever.

It’s about crafting an atmosphere that’s less “block out” and more “blend in.”

7. Strategic Use of Outdoor Structures

Gazebos and pergolas are not just for sipping lemonade and admiring the roses; they’re also strategic players in your quiet game. With a little creativity, these structures can serve as physical barriers against noise, bouncing and muffling the sounds away from your serene spot.

It’s vital to place these structures between your house and the source of the noise – the highway. Each piece must be strategically positioned to protect your quiet. Gazebos, with their solid roofs, can deflect noise upwards, while the slats and latticework of a pergola can disrupt sound paths.

And if you’re feeling extra crafty, draping fabrics or adding outdoor acoustic panels to these structures can up their sound-dampening game even more.

8. Windows and Insulation for the Home

Now, let’s talk about when the outside noise becomes an indoor annoyance.

Soundproof windows are like having your very own silence bubble. They’re designed to keep the racket out so you can enjoy your indoor tranquility.

But if you’re not up for replacing windows, there are more tricks in the book. Insulated curtains can be a quick fix. And for the DIY enthusiast, crafting a window plug is a hands-on solution that can significantly cut down on the invasion of sound.

But what about the walls? Upgrading your existing insulation or installing some if you haven’t already can make a world of difference. MLV is another fantastic option for blocking noise. You can install it either over existing drywall or beneath new drywall. Whichever way you choose, it’s going to significantly reduce that troublesome noise.

Additional Tips: Fine-Tuning Your Peaceful Backyard Plan

When lining up your noise-fighting tactics, you want every player to bring their A-game. To make sure your backyard becomes the tranquil oasis you’re aiming for, here are some additional tips that’ll give you the edge:

  • Combination of methods: Each method brings a unique sound-busting quality to the table. When you layer them up, they work together like a finely-tuned orchestra, each part enhancing the others to create a symphony of silence. It’s not about one big move; it’s about the collective power of several smart, targeted strategies.
  • Consult a professional: Sometimes, you need to call in the cavalry. If you’re facing a difficult noise problem, a landscape architect or an acoustical consultant can be the solution. They’ve got the expert knowledge to design a noise-reduction plan that’s as precise as it is effective.

Before You Begin: Essential Considerations

Now, before we wrap up the article and you embark on your backyard quiet crusade, keep these crucial considerations in mind:

  • Local regulations: Always check with local authorities to ensure that any modifications you plan to make are within local regulations, particularly when building structures or fences.
  • Maintenance: Consider the long-term maintenance of whatever solutions you implement, as some vegetation and barriers may require ongoing care.
  • Budget: Your budget will likely dictate the extent to which you can implement these noise reduction strategies. Some, like building a wall, can be quite expensive.
  • Neighborly coordination: If noise pollution affects the whole neighborhood, collective action can be more effective and financially viable. Group efforts in building barriers or planting vegetation can foster community and split costs.
  • Future developments: Keep an eye on potential developments in your area that may affect noise levels in the future. This can influence both the urgency and the type of noise reduction measures you decide to implement.

Final Thought: The Value of Quietude

As we conclude, consider the broader impact of your noise reduction efforts. A quiet backyard can become a haven for wildlife, a natural stress reducer, and an outdoor extension of your living space. It’s a meaningful investment in your home’s ambiance and the quality of your family’s life.
