Backyard Recording Studio: DIY Sound Treatment

Okay, let’s transform that underutilized space into your personal sonic playground! Many musicians dream of having a dedicated creative space, and a backyard recording studio can be the answer, offering an escape just steps away. Companies like Auralex Acoustics provide a range of soundproofing materials, but the good news is that effective DIY treatments are totally achievable. Consider bass traps, they are essential for taming low-frequency rumble in small spaces. Even legendary producers like Rick Rubin often emphasize the importance of room acoustics in achieving a great sound. Think of your backyard recording studio as an instrument itself, one that needs careful tuning to capture the best possible recordings.

Designing Your DIY Backyard Recording Studio: Sound Treatment Essentials

Creating a backyard recording studio can be an exciting and rewarding project. However, achieving professional-quality sound requires careful planning and a focus on effective sound treatment. This guide will walk you through the essential steps to soundproof your space and optimize its acoustics, ensuring crisp, clean recordings right in your backyard.

I. Understanding the Need for Sound Treatment

Before jumping into the DIY aspect, let’s understand why sound treatment is crucial for a "backyard recording studio". Sound inside a typical room bounces off hard surfaces like walls, ceilings, and floors. This creates reflections and reverberations that muddy your recordings. Sound treatment aims to control these reflections, creating a more accurate and pleasing sonic environment. Think of it like this: without sound treatment, you’re hearing the room more than the instrument or voice.

Here’s a breakdown of common acoustic problems:

• Echoes: Distinct, delayed repetitions of a sound.
• Reverberation: A lingering sound after the original sound has stopped.
• Standing Waves: Specific frequencies that get amplified or cancelled out in certain areas of the room, leading to uneven sound.
• Flutter Echoes: A rapid succession of echoes, often heard between parallel surfaces.

II. Assessing Your Backyard Recording Studio Space

Before you start building acoustic panels, take some time to evaluate your backyard recording studio space:

1. Measure the Room: Accurately measure the length, width, and height of your space. This data is crucial for calculating room modes (frequencies that resonate strongly in your room) and determining the amount of sound treatment you’ll need.
2. Identify Problem Areas: Clap your hands loudly in different parts of the room. Pay attention to how the sound behaves. Where do you hear echoes? Where does the sound feel "boomy" or muffled?
3. Note Existing Surfaces: What are your walls made of? Concrete? Wood? Drywall? This will affect how sound reflects and absorbs. Also, note the presence of windows, doors, and other features that might need specific treatment.
4. Consider Noise Sources: Identify external noise sources like traffic, neighbors, or wildlife. While soundproofing is a separate topic, it’s important to consider when planning your sound treatment strategy.

III. DIY Sound Treatment Options: Absorption

Acoustic absorption reduces sound reflections by converting sound energy into heat. This is crucial for taming excessive reverberation and creating a cleaner recording environment.

Here are some popular DIY absorption options:

• Acoustic Panels: These are fabric-covered panels filled with sound-absorbing material like mineral wool, fiberglass, or recycled cotton. They’re highly effective at absorbing mid-to-high frequencies.
  • Construction: Build a wooden frame, stuff it with your chosen absorbent material, and wrap it with acoustic fabric.
  • Placement: Strategically place panels at first reflection points (the points on the walls and ceiling where sound waves bounce from your speakers to your listening position). You can find these points using the mirror trick: have someone sit in your listening position while you move a mirror along the wall. When you can see the speaker in the mirror, you’ve found a first reflection point.
• Bass Traps: Bass traps are designed to absorb low-frequency sound waves, which are often the hardest to control. They are typically placed in the corners of the room, where bass frequencies tend to accumulate.
  • Construction: Bass traps can be built using the same materials as acoustic panels, but are often thicker and larger to effectively absorb lower frequencies. Corner bass traps are particularly effective.
  • Placement: Place bass traps in all four corners of your room. You can also stack them to increase their effectiveness.
• Blankets/Moving Blankets: While not as effective as dedicated acoustic panels, heavy blankets can provide some sound absorption, especially for temporary setups.
  • Construction: Simply hang blankets on walls or suspend them from the ceiling.
  • Placement: Experiment with placement to find the best results. They can be particularly useful for reducing reflections in specific areas.

• DIY Diffusers: Adding diffusion can greatly help to scatter sound waves, reducing standing waves and creating a more lively acoustic environment.

  • Construction: One type of diffuser is the Skyline Diffuser which can be easily constructed using varying lengths of wood blocks and gluing them together.
  • Placement: Place diffusers on the back wall of your studio or where reflections from the speakers hit.
  • Note: These are more complex to build than absorbers, but can add a desirable sonic element to your studio.

IV. DIY Sound Treatment Options: Diffusion

While absorption reduces sound reflections, diffusion scatters them. This helps create a more natural and spacious sound, preventing dead spots and flutter echoes.

Here are some DIY diffusion options:

Type of Diffuser	Construction Materials	Placement Strategies	Sound Effect
Quadratic Residue Diffuser (QRD)	Wood, MDF, or foam; requires precise calculations	Rear wall, side walls, or ceiling; ensure proper spacing	Scatters sound waves evenly across a wide range of frequencies
Poly Cylindrical Diffuser	Curved surface made of wood, plastic, or metal	Corners, walls, or ceilings; can be used horizontally or vertically	Diffuses sound waves while also providing some absorption at lower frequencies
Bookshelves (strategically filled)	Existing bookshelves filled with books of varying sizes	Along walls, particularly in areas with flutter echoes	Creates a random scattering of sound waves, reducing flutter echoes and comb filtering
DIY Skyline Diffuser	Wood blocks of varying lengths	Rear wall, side walls, or ceiling	Scatters sound waves evenly across a wide range of frequencies

V. Strategic Placement is Key

The effectiveness of your DIY sound treatment depends heavily on proper placement.

Here are some general guidelines:

• First Reflection Points: As mentioned earlier, treat first reflection points on the walls and ceiling with absorption.
• Corners: Place bass traps in all four corners to address low-frequency issues.
• Back Wall: Consider using diffusion on the back wall to create a more spacious sound.
• Mixing Position: Ensure that your mixing position is relatively symmetrical and free from major acoustic problems.
• Experiment: Don’t be afraid to experiment with different placements to find what works best for your space. Listen carefully to your recordings and make adjustments as needed.

VI. Soundproofing vs. Sound Treatment: Understanding the Difference

It’s important to distinguish between soundproofing and sound treatment.

• Soundproofing aims to block sound from entering or exiting the room. This typically involves sealing gaps, adding mass to walls, and using sound-dampening materials. This can get expensive.
• Sound Treatment aims to improve the sound within the room by controlling reflections and reverberation. This is what we’ve been focusing on in this guide.

While soundproofing can be beneficial, it’s often more complex and expensive than sound treatment. Start with sound treatment to optimize your recording environment, and then consider soundproofing if you still have issues with external noise.

So, there you have it! A few affordable and effective ways to get your backyard recording studio sounding less like, well, a backyard, and more like a professional space. Experiment, have fun, and don’t be afraid to tweak things until you find the sweet spot for your ears and your music. Happy recording!
