Crystal-clear audio is the secret behind every captivating social video you love. However, it’s only sometimes about having the most expensive microphone or high-end equipment. Many successful creators achieve professional-grade sound by mastering the art of soundproofing. And guess what? You can learn it too.

A study by Tech Smith shows that clear audio is the primary reason 75% of videos are assumed to be perfect. So, let’s understand the soundproofing secrets that’ll elevate your content and keep your audience engaged.

In this blog post, we’ll learn everything from material choices, like a soundproof tile, to hacks, like repurposing furniture for acoustic treatment. Keep reading.

Pro Techniques You Can (And Should) Use

Let’s get to the point and learn about pro-level soundproofing techniques that will elevate your audio game. These practical solutions are used in studios worldwide, and you can use them to transform your space.

Decoupling & Isolation

The sound is sneaky. It doesn’t just travel through the air; it vibrates through solid objects, turning your walls, floors, and ceilings into passways. Decoupling separates rigid structures, creating a gap that prevents sound vibrations from quickly passing through. 

There are a few different techniques; the right one for you will depend on your budget and DIY skills. One popular method is using resilient channels. These thin metal channels are attached to your existing framing, and then a new layer of drywall is screwed onto them. 

The channels flex slightly, absorbing some sound energy before transferring to the second layer of drywall. This can significantly reduce noise, especially when combined with other soundproofing materials.

Mass Loaded Vinyl (MLV)

Mass-loaded vinyl (MLV) is a dense, flexible material that blocks sound entry and prevents it from ruining your audio. It is packed with tiny particles (usually barium sulfate or calcium carbonate) that add heft and density. 

When sound waves hit this dense barrier, they lose energy and struggle to pass through. This means less noise escaping your recording space and less external noise creeping in. It’s a win-win for your audio quality.

Acoustic Tiles

If your recording space sounds like a cave, it’s time to bring acoustic tiles. They are your first line of defense against mid- and high-frequency reflections. They act like sound sponges, absorbing sound waves that bounce around your room and create an unprofessional sound. Acoustic tiles are made of porous materials like mineral wool, fiberglass, and plastic fiber, wrapped in fabric for a sleek look.

With various shapes, sizes, and colors available, you can create an eye-catching acoustic feature wall that doubles as a sound-absorbing wall. Strategically placing acoustic panels can reduce reverberation, which should be 0.15 to 0.3 seconds, making audio cleaner and crisper.

Mic Placement & Directionality

Your microphone perceives sound in specific ways depending on its type and placement. By mastering these two elements, you can shape your audio’s character and dramatically improve its quality without spending a dime. First, let’s discuss microphone types. 

• Cardioid mics: These mics capture sound primarily from the front and reject noise from the sides and rear.
• Omnidirectional mics: These mics pick up sound equally from all directions.
• Figure-8 mics: These mics capture sound from the front and back while rejecting it from the sides.

Knowing your mic’s polar pattern is vital to placing it correctly. For example, a cardioid mic should be pointed directly at your sound source to capture the most focused sound. An omnidirectional mic can be placed in the center of a room to capture a more natural, ambient sound.

Now, let’s get into placement. Even a slight change in mic position can make a huge difference. You might get a boomy or distorted sound if you place a mic too close to a sound source. Too far away, and you’ll pick up too much room noise. Start by placing the mic 6-12 inches away and slightly off-center for voice recording to avoid plosives. Experiment with distance and angle to find what sounds best for your voice.

Taming Cable Noise

Cable noise is common, especially in home studios where space is often limited. It can manifest as a low hum, buzzing, crackling, or even a distinct tapping sound. The causes vary, ranging from electrical interference to vibrations caused by foot traffic or air conditioning.

Keep audio and power cables separated as much as possible. Running them parallel can lead to interference. If they must cross, do so at a 90-degree angle to minimize contact. Avoid running cables across the floor where they can be easily bumped or stepped on. Instead, use cable clips or ties to secure them along walls or ceilings.

Eco-Friendly Materials for Pro-Level Audio

Green materials are safe and sound for the environment and are an excellent choice for absorbing sound in your studio. These materials include plant fibers, leaves, and even fruit stones. When used as sound absorbers, they can help reduce noise pollution and produce professional-quality audio. 

The study found that thicker, denser materials or those with an air cavity behind them better absorb sound, especially low-frequency sounds. This is because the sound has more space to travel and get trapped. 

Many different green materials can be used for soundproofing rooms. This means we have many options for making our YouTube studio quieter. However, there are some challenges to using these green materials. They can be sensitive to moisture, rot over time, and may not be very fire-resistant.

Furniture as Acoustic Allies

Couches, chairs, and rugs can also be used for soundproofing. Soft furnishings act like sound sponges, absorbing sound waves that cause echoes and reverberations. Plush velvet and Vinyl fabric are sound absorbers. They are proven more effective in absorbing low—and medium-pitched noises. 

The same goes for your armchairs, ottomans, and any other upholstered furniture you have. The thicker and denser the material, the better it will absorb sound.

FAQs

Is It Possible to Completely Soundproof a Space?

While complete soundproofing is theoretically possible, achieving it in practice is extremely difficult and expensive. It requires isolating the space from all vibrations and sound waves, using specialized materials and construction techniques. Significant noise reduction is usually achievable, but eliminating all sound transmission is a challenge.

Does Thermocol Absorb Sound?

Yes, thermocol, also known as expanded polystyrene (EPS), can absorb sound, especially at medium to low frequencies. Its cellular structure, consisting of numerous tiny air pockets, helps to trap sound waves and convert their energy into heat, thus reducing their intensity.

What is the Cheapest Way to Soundproof a Wall?

The cheapest way to soundproof a wall is to use thick blankets or moving pads.

Hang them on the wall using nails or hooks. This will help absorb sound waves and reduce noise transmission.

We’ve covered a lot of ground, and now you know how to soundproof your YouTube studio. Remember, every recording space is unique, so experiment and find what works best for you. With a little effort and creativity, you can achieve professional-quality audio that will take your content to new heights.

But soundproofing is more than just creating great videos. It also promotes an inclusive environment. Loud noises often manifest as hypersensitivity. As highlighted by Felt Right, around 15% of people experience some form of sensory processing disorder (SPD). This makes every day sound overwhelming and even painful.

Implementing these soundproofing strategies will improve your audio and potentially create a more comfortable space for people with sound sensitivities. Now, it’s your turn to put these soundproofing secrets into action. Share your experiences, ask questions, and let’s create a community of YouTubers dedicated to crafting incredible audio.
