What's the Difference Between Acoustic Treatment and Soundproofing?
The first thing to learn, when setting up your domestic podcast recording space, is the difference between acoustic treatment and soundproofing:
Acoustic treatment: This reduces reverberation and controls how vibrations of sound waves act inside a room to enhance audio quality. When treating a room acoustically, you are going to use sound-absorbing panels that will assist in minimizing echo and reflections.
Soundproofing: When soundproofing, you aim at both blocking sound from entering the studio and sounds going outside. Soundproofing a studio also requires fiberglass panels or mass-loaded vinyl for sealing of the walls effectively.
Acoustic Treatment: How to Reduce Reverberation for Better Sound
Acoustic treatment minimizes reverberation. Sound waves tend to bounce off hard surfaces, creating a muffled and unclear sound.
Here’s what you can use to reduce reverberation:
Acoustic Foam: Lightweight and affordable, it absorbs high frequencies, reducing echo.
Pros: Easy to install, budget-friendly.
Cons: Limited effectiveness on low frequencies.
Recommended Product: Udderly Quiet® Pyramid Foam, ideal for home-based studios.
Fiberglass Panels: Absorb both high and low frequencies, offering broader sound absorption.
Pros: Effective across the sound spectrum.
Cons: Pricier than foam.
Recommended Product: Soundproof Cow Art Acoustic Panels, customizable for a professional look.
B. Bass Traps
Placed in the room’s corners, bass traps are essential for managing low frequencies.
Recommended Product: Udderly Quiet® Corner Bass Traps by Soundproof Cow for effective bass control.
C. Sound Diffusers
Diffusers scatter sound waves to prevent direct reflections that can muddy audio clarity.
Practical Tip: DIY diffusers can be made with materials like wood and foam.
Recommended Product: Bubos 36 pieces Acoustic Diffusers for ideal triangular diffusion and sound absorption.
Studio Soundproofing: How to Block Sound In and Out
If you want to avoid noise from outside or prevent sounds from leaking, soundproofing is essential, especially if you share living space. Here’s how:
A. Walls and Ceilings
For effective wall isolation, add layers of mass-loaded vinyl or install a double wall.
Mass-Loaded Vinyl: Dense and flexible, it’s excellent for blocking sound.
Recommended Product: Acoustical Surfaces Mass Loaded Vinyl (MLV).
B. Flooring
Floors can be soundproofed with specific underlays for isolation.
Practical Tip: Use UnderBlock underlayment to reduce vibrations.
C. Door and Window Seals
Doors and windows are often major sources of sound leakage; soundproofing the windows with specific inserts helps reduce external noise by up to 80%.
Recommended Products: Seal Kits for effective door sealing.
DIY Acoustic Treatment Solutions
If you're on a budget, there are DIY solutions for improving acoustics at. While not optimal, they’re useful in a pinch or for beginners with limited resources:
Heavy Blankets: Cover reflective surfaces or create a mobile “booth” around the microphone.
Furniture and Rugs: Adding bookshelves, rugs, and curtains can help with sound absorption.
Practical Tip: Place furniture strategically around the microphone to block early reflections.
Tools and Equipment to Enhance Studio Sound
Specific tools can also help eliminate interference during recording in non-optimized rooms:
Microphones: Choosing the right microphone can make a big difference in reducing background noise. Dynamic mics like the Shure SM7B are less sensitive to the environment than condenser mics, making them ideal for home studios.
Microphone Reflection Shields: Create a barrier around the mic, limiting side reflections. Options like the SE Electronics Reflection Filter RF-X are excellent for reducing reverb and ambient noise.
Portable Solutions: these can include Portable Recording Booths (Foldable booths are ideal for recording in shared spaces) or Mountable Acoustic Panels (Easy to hang and remove, perfect for flexible use).
Choosing the Right Room for Your Studio
Choosing the ideal room for a studio isn’t always an option. As you may know, most podcasts start out with minimal resources, often recorded in a bedroom.
This doesn’t prevent a podcast from succeeding or delivering high-quality sound, but if you have the choice, pick a room with minimal open space. Fewer windows and hard surfaces mean less sound reflection.
Alternatively, consider a closet. Many podcasters use closets since hanging clothes provide natural sound insulation.
Recording Techniques and Environmental Tips
Even if you’re a beginner podcaster, soundproofing your recording space should be a priority.
Not only for your audience, who expect the highest quality, but because editing poorly recorded audio is time-consuming, and if podcasting is your business, time is money.
Optimizing your recording technique can reduce post-production editing needs. If you don’t have access to editing software (check the author's note if you want to know more about it!) you can follow these tips:
Mirror Test: To identify reflection points, place a mirror along the walls and observe where it reflects the microphone. Install acoustic panels in these spots.
Record in Small Spaces: Reduce echo by recording in small, absorbent spaces with minimal reflections.
Close Microphone Distance: Reduce the distance between you and the microphone, positioning it close to your mouth. This minimizes reverberation and environmental noise.
Conclusion
A well thought out combination of acoustic treatment and soundproofing can transform even a home room into a professional studio.
Whether you choose DIY solutions or advanced equipment, every detail contributes to your podcast's final audio quality.
I hope these tips help you create an optimal acoustic environment, improve your listeners' experience, and build audience loyalty.
Now is the time to make your voice a professional and memorable presence. Happy recording!
