7 Essential Acoustic Treatments for Home Recording Studios

Creating a professional-sounding studio isn’t just about expensive gear. Untreated rooms can ruin your mix with echoes and uneven bass. The good news? You don’t need to cover every inch of your space. Treating just 30-40% of your room can make a huge difference. Here’s a quick overview of the 7 acoustic treatments you need:

• Bass Traps: Absorb low frequencies in corners.
• Acoustic Panels: Reduce echoes and mid-range reflections.
• Diffusers: Spread sound evenly across the room.
• Equipment Placement: Position monitors and gear for accurate sound.
• Sound Isolation: Block outside noise and keep sound in.
• DIY Options: Affordable fixes like duvets and homemade panels.
• Professional Installation: For complex setups or precise results.

Quick Tip: Start with bass traps in the corners and panels at first reflection points for the biggest impact.

ACOUSTIC TREATMENT – How to Build a KILLER Home Studio

1. Bass Traps: Managing Low Frequencies

Bass traps are a key solution for tackling low-frequency sound issues in home studios. These acoustic treatments help reduce the low-frequency booms that often occur in untreated rooms, improving the accuracy of your mixes.

Bass traps work by absorbing low-frequency energy that tends to build up where walls and ceilings meet. Without them, this build-up can cause problems with balance and clarity, making it harder to produce precise mixes.

"Acoustical Bass Traps will help control low frequencies and smooth out the sound in your mixes, listening rooms, and home theatres." – Acoustical Solutions ^[2]

Best Places to Install Bass Traps

• Vertical Corners: Install bass traps in all four corners where walls meet.
• Wall-Ceiling Junctions: Place them where the walls meet the ceiling.
• Behind Monitors: Adding Rockwool absorber panels behind your speakers can help reduce bass reflections.

Types and Costs of Bass Traps

In the UK, bass traps are available in various types and price ranges, depending on materials and performance:

Installation Tips

For the best results, clean the surfaces thoroughly before mounting your bass traps. Apply adhesive just before installation to ensure a firm hold. Proper placement and secure installation are critical for getting the most out of your bass traps.

2. Acoustic Panels: Mid-Range Sound Control

Acoustic panels help manage mid-range frequencies and minimise echoes. By absorbing reflected sound waves, they reduce unwanted noise that can interfere with your recordings.

How Acoustic Panels Work

These panels work by absorbing sound energy and converting it into heat, which helps reduce noise and improves sound clarity. For effective sound absorption, look for panels with an NRC (Noise Reduction Coefficient) rating of 0.7 or higher.

Panel Types and Pricing

Strategic Panel Placement

Proper placement is key to making the most of your acoustic panels. Focus on these areas:

• First Reflection Points: Install panels where sound first reflects off walls.
• Ceiling: Place panels above your mixing area to catch overhead reflections.
• Rear Wall: Add panels behind your listening position to reduce echoes.

Professional Mounting Solutions

Here are two reliable methods for mounting acoustic panels:

• Impaling Clips: These are easy to use and provide strong support. Attach the clips about 10 cm inside the panel edges, apply construction adhesive, and press the panel into place. This method is stable and works well for most setups.
• Z-Clips: Perfect if you need to adjust or remove panels later. While installation requires precise measuring, Z-clips allow flexibility and cause minimal wall damage during repositioning.

Performance Considerations

Panel thickness plays a big role in their performance. Thicker panels (10 cm or more) are better for absorbing low frequencies, while thinner ones (5–7.5 cm) are more suited for managing mid-range sounds. Combining panels of different thicknesses often provides the best overall sound control.

Next, we’ll look at diffusers to further fine-tune your studio’s acoustics.

3. Diffusers: Sound Wave Distribution

Sound diffusers are acoustic tools designed to spread sound waves evenly across your studio, creating a balanced and natural sound. Unlike absorbers, diffusers scatter sound waves, helping to keep the room’s energy intact.

How Diffusers Work

Sound waves travel in straight lines and bounce off surfaces. In rectangular rooms, this often leads to slap echoes as sound bounces back and forth between parallel walls. Diffusers disrupt these reflections by spreading the waves in different directions. When combined with other treatments, they can greatly improve the overall acoustics of your space.

Types of Diffusers and Their Applications

Strategic Placement

To get the most out of diffusers, placement is key. Focus on these areas:

• Rear Wall: Install diffusers behind your listening position to stop sound waves from bouncing directly back to your ears.
• Front Wall: Use them to scatter reflections from your monitors.
• Ceiling: Place diffusers overhead to handle reflections from above.

Performance Optimisation

"The rear wall, behind the listening position, is the most essential area to add diffusion – next, the front wall and ceiling need to be addressed" ^[3] – Sound Acoustic Solutions

For the best results, keep these factors in mind:

• Coverage Area: Sound travels approximately 30.5 cm per millisecond ^[4].
• Material Choice: Materials like fibreglass, wood, or PVC should be chosen based on your acoustic needs and budget.

Combining with Other Treatments

Diffusers are most effective when used alongside other acoustic treatments like panels and bass traps. Together, they create a balanced sound environment that reduces unwanted reflections while preserving the room’s natural feel.

Professional Integration

When installing diffusers, think about both their look and their function. Space them evenly across your treatment areas to ensure consistent sound coverage throughout your studio.

4. Studio Setup: Equipment Placement

Getting your equipment placement right is crucial for accurate sound. Your monitors should be at head height, forming an equilateral triangle with 30° inward angles.

Monitor Positioning Basics

This setup helps manage reflections and ensures your monitors perform their best.

Key Placement Advice

Place your monitors along the longest wall of your room. This reduces side-wall reflections, especially useful in smaller rooms where sound issues can be more noticeable.

"Reflections from the desk and other nearby equipment can be a big problem, so sorting out the location of the monitors themselves should be the first priority before fixing up any acoustic treatment." – Paul White ^[6]

Using a Desk for Monitors

If your monitors are on a desk:

• Add foam isolation pads to reduce vibrations.
• Position them near the desk’s front edge.
• Ensure the desk is lower than the monitors.

Managing Reflections

To identify problem areas, try the mirror test: if you can see the tweeter in the mirror, that surface needs treatment ^[6].

Fine-Tuning Your Setup

After initial placement:

• Step 1: Roughly position the monitors, ensuring nothing blocks the sound path.
• Step 2: Play consistent bass notes and adjust the speakers slightly to minimise uneven bass spots.
• Step 3: Refine the speaker and listening positions for better bass clarity.

Keep in mind that room modes – resonances caused by room dimensions matching sound wavelengths – can heavily affect your sound. Smaller rooms often deal with more uneven resonances ^[5], making precise placement even more important.

5. Sound Isolation Methods

Acoustic treatments improve sound quality inside your studio, but sound isolation focuses on keeping unwanted noise out – or in. To gauge your isolation efforts, you’ll need to understand STC ratings.

Understanding STC Ratings

Sound Transmission Class (STC) ratings show how well building materials block sound. For home studios, here’s what to aim for:

Key Isolation Components

Mass and Density
Install Mass Loaded Vinyl (MLV) behind 15.875 mm (5/8″) thick drywall. Use acoustic sealant to ensure all edges are sealed properly ^[8].

Door Treatment

• Hollow core doors: STC ratings in the low 20s
• Solid core doors: STC ratings of 30 or higher
• Door seal kits: Can boost STC ratings by up to 20 points

Air Gap Sealing
Close all gaps, including those at wall-floor intersections, around electrical outlets, window frames, and HVAC ducts, to prevent sound leaks.

Professional Installation Options

For larger projects, professional services can take your isolation to the next level. Companies like Sound of Silence offer:

• Installation of sound isolation clips for walls and ceilings
• Double-pane, laminated glass installations
• Modifications to HVAC systems to minimise sound transmission
• Custom door sealing solutions

Affordable Isolation Materials

Here are some materials that balance cost and performance:

Advanced Isolation Techniques

Decoupling
Physically separate structural elements using sound isolation clips. This can achieve STC ratings in the mid-to-upper 50s while reducing low-frequency noise transfer ^[8].

Damping Compounds
Apply specialised compounds like Green Glue between drywall layers. These compounds convert sound energy into heat, enhancing isolation performance ^[7].

6. Budget-Friendly DIY Solutions

You don’t need to break the bank to improve your room’s acoustics. These DIY methods are practical and affordable, offering solid results without requiring expensive materials or tools.

Duvet Sound Absorption

A high-tog duvet can be a surprisingly effective way to absorb sound.

"A kingsize duvet works out a lot cheaper, it can be easily hung and later removed without damaging the walls, and it generally works over a wider bandwidth than most foam tiles will." ^[9]

To get the best results, hang the duvet slightly off the wall (2.5–5 cm). This setup is particularly useful for reducing low-frequency reflections, especially behind vocalists or instruments.

DIY Acoustic Panels

You can make your own acoustic panels at home with a few simple materials. Here’s what you’ll need:

By assembling these yourself, you can save a significant amount of money while still achieving effective sound treatment.

Custom Bass Traps

For better control of low frequencies, build corner bass traps. A good size to aim for is 190 cm high, 45 cm wide, and 10 cm deep. Positioning the material slightly away from the wall can improve performance almost as much as adding extra thickness ^[11].

Strategic Placement Tips

Where you place your DIY treatments matters.

"Reflections from nearby walls are responsible for much of the coloration that so many people try to solve by buying more expensive mics or mic preamps, so instead of laying out more cash, hang a thick duvet behind the singer and see how much that cleans up the sound of a bedroom recording." ^[10]

These simple adjustments can make a noticeable difference, especially in home recording setups. Pair these DIY solutions with professional techniques for a well-rounded acoustic setup.

7. Expert Installation Services
