One of the very first problems most podcasters encounter once they begin recording is how to get clean, crisp audio.

This isn't just about picking a great microphone or other podcasting gear; it is also about how to improve acoustics in your recording space.

Unfortunately, the room you choose may not always have the best characteristics to guarantee top sound.

There's an easy, pretty inexpensive way out: acoustic panels. Among all the possible solutions to perfect your home or professional studio, panels are the easiest and most trustworthy option.

There's something for every wallet, but making the right decision means knowing how to choose the panels and where to place them.

In this post, I'll go over the key points for finding the right panels and show you how to use them effectively.

But I'll also share with you some products that I have liked and that get great reviews.

So, if you're ready to buy and don't need the extra tips, feel free to jump to the second part of this article.

Let's get started!

What Are Acoustic Panels for Podcasts Used For?

Acoustic panels do not block external or internal noise as many believe (there are other soundproofing equipment for that!).

Instead, acoustic panels, as their name says, are designed to improve the acoustics inside a room.

• They don’t block outside noise (like traffic, voices, or other sounds). For this type of isolation, you’d need specific materials like soundproof panels, drywall with layers of rock wool, or high-density vinyl.

• They don’t stop sound from escaping the room. For instance, recording noise or music can still be heard outside.

Acoustic panels serve the purpose of absorbing and managing sound reflections within a space. This helps to:

• Reduce echo and reverb.

• Improve sound clarity.

• Create the perfect environment for recording or listening.

  

How to Choose Acoustic Panels for Podcasts

When selecting acoustic panels for your recording studio, consider these factors:

1. Panel Thickness

Thickness plays a crucial role:

• 2-Inch Panels: The most common option, perfect for most home studios. They effectively absorb mid-to-high frequencies, reducing echoes and reverb. This ensures clear and crisp vocal recordings.

• 4-Inch Panels: Recommended for greater control over low frequencies, especially in larger spaces with reflective surfaces. These are typically used in professional studios.

2. Material

Material is another important factor, particularly when it comes to price:

• Acoustic Foam: The most popular and budget-friendly choice. These panels are lightweight, easy to install, and they are great for absorbing mid-to-high frequencies. Ideal for home studios.

• Polyester or Fiberglass: These materials are more expensive but excel at absorbing a wider range of frequencies. Perfect for those seeking near-complete acoustic interference elimination. Best suited for professional recording studios.

3. Noise Reduction Coefficient (NRC)

Acoustic panels are rated with an NRC value, which measures their sound absorption on a scale from 0 (no absorption) to 1 (maximum absorption):

• Look for panels with an NRC between 0.7 and 0.9 for solid sound control.

• Values above 0.9 are excellent but often unnecessary for non-professional podcast setups.

4. Budget

Your budget is, of course, an important consideration:

• Affordable: Basic acoustic foam, perfect for beginners.

• Mid-Range: Polyester panels offer a good balance between performance and cost.

How to Know if Your Panels Are Working Properly

It’s crucial to ensure your panels are truly improving your studio’s acoustics before you start recording. Here’s how to check:

1. The Clap Test

The easiest way to evaluate acoustic treatment:

• Stand in the center of the room.

• Clap your hands loudly and listen to the sound.

• If you hear echo or reverb: You may need to add or reposition panels.

• If the sound is dry and controlled: The panels are doing their job.

2. Test Recording

Record a short audio track while speaking into the mic at your usual distance.

• Listen closely to the playback:

• If the sound is clean and echo-free: The panels are absorbing reflections effectively.

• If you hear reverb or a "hollow" sound: Additional adjustments may be needed.

3. Reverb Test

Use online tools or mobile apps to measure the reverb time (RT60) in your room.

• Recommended tools:

• Buzzi Space RT60: Includes a video tutorial on how to use it.

• REW (Room EQ Wizard): A versatile option for detailed room analysis.

• Ideal reverb time for podcasting: Between 0.2 and 0.4 seconds.

• If it’s higher: You may need to cover more surface area with panels.

These simple tests will help you confirm if your acoustic panels are improving your recording environment or if further tweaks are necessary.
