This article explains how to create a quiet sanctuary to block traffic noise or household sounds through practical and effective techniques. Importantly, it unveils an AI Noise Cancellation Assistant, a leader in real-time Voice AI, that serves as a soundproofing addition to increasing productivity during online interactions.

Sound, Music, and Noise

Did you know normal human ears are sensitive to frequencies between 20 and 20,000 Hz? But our hearing isn’t limited to this: all detectable sounds can be interpreted into musical “frequency zones” with their “feels.” That’s why knowing how to soundproof a room is more vital than you might think.

What makes sound, music, and noise different?

Sound

Sound is an energy type that vibrations make. “We live surrounded by vibrations that are extremely important in how we perceive the world,” says neuroscientist Daniel Huber. Haven’t you ever listened to the rain and automatically felt a sense of calm?

So, it’s no surprise that sounds are contributing to the future of telecoms. Thanks to sounds, humans and other animals can communicate and understand one another using the pitch of their voice or accent.

Moreover, Brain-Computer Interfaces (BCIs), as a bridge between your brain and an external device, enable interaction with machines. Increasingly, they improve object control by translating the user’s brain activity into commands. Thus, BCIs promise to revolutionize the future of work.

Music

Music psychologically affects our emotions. Researchers have revealed that listening to enjoyable music releases dopamine in our brains. Dopamine is a chemical that gives us feelings of pleasure, satisfaction, and motivation.

For example, according to Oliver Sacks, one of the best-known neurologists, music elicits “emotions and associations that had been long forgotten, giving the patient access once again to mood and memories, thoughts and worlds that had seemingly been completely lost.” That’s why patients become unchained by melody.

Conversely, disruptive background noises negatively affect our feelings and emotions. And this once again highlights the importance of knowing how to soundproof a room by canceling noise.

Noise

The term “noise” has different usages, such as sounds at deafening levels and unwanted sounds. According to the Merriam-Webster dictionary, noise means sound, especially one “that lacks an agreeable quality or is noticeably unpleasant or loud.”

According to Hans Ising and Bernd Kruppa, scientists specializing in environmental health, noise can be a non-specific biological stressor. The latter can elicit reactions that prepare the body for fight or flight.

For example, high levels of noise and sounds immensely affect our physical and mental health. Specifically, they can cause hearing loss and reduced well-being, as the National Library of Medicine states.

Before Learning How to Soundproof a Room: Identifying the Source of Noise

Interested in “How do you soundproof a room so others can’t hear?” First, identify the type of noise you’re dealing with.

• Noise Can Be Airborne: It travels through the air and refers to sounds like voices, music, and traffic. For instance, noise from your neighbors chatting or cars honking outside is airborne.

• Impact Noise: This type of noise happens when objects collide, causing vibrations to travel through floors and walls, unlike airborne noise. For example, impact noise comes from someone walking heavily or dropping something upstairs. It can be disruptive, especially in multi-story buildings.

Knowing the difference between noise types helps you pick the proper soundproofing techniques for your space. These techniques can include blocking footsteps from the apartment above or a chair scraping the floor.

Most Common Soundproofing Materials or Methods

Soundproofing doesn’t let sound enter or leave a space. For instance, adding mass-loaded vinyl to walls prevents noise from seeping into a room.

You may ask, “What’s the difference between soundproofing and sound-absorbing?” The latter reduces echo to improve sound quality in a room. Acoustic panels or foam, for example, help absorb sound waves, making a recording studio or home theater clearer and less reverberant.

So, soundproofing keeps noise in or out, while sound-absorbing enhances the sound environment inside a room.

Now, let’s discuss the best materials to block sound.

What Is the Best Material to Block Sound?

Creating a quiet space involves using various soundproofing methods. For instance, you can choose an AI Meeting Assistant for Noise Cancellation or equipment, such as acoustic panels and noise-canceling headphones.

Let’s discuss how to soundproof a room using different materials and techniques to block noise.

Gaps and Cracks

Noise loves to sneak in through tiny gaps around doors and windows. So, use weatherstripping tape to seal these gaps. Moreover, you can apply acoustic caulk to larger cracks because it’s flexible and easy to fix.

Acoustic Panels

Acoustic panels are foam or fabric-covered boards that absorb sound waves and reduce echoes. Consider mounting them on walls to reduce echoes and airborne noise, especially in a recording studio, home theater, or living room.

Dense Walls

Heavier walls more successfully prevent sound transmission. So, consider adding mass by installing mass-loaded vinyl (MLV) sheets or extra drywall layers. Applying MLV behind drywall can be one of the best answers to the question, “How to soundproof a room?”

Carpets and Rugs

Hard floors can make the noise worse. Thankfully, you can absorb unwanted sounds by adding thick carpets or area rugs. Additionally, you can lay down carpets or area rugs to absorb impact noise. Add dense underlays beneath them for better results.

Soundproof Doors

Standard doors often lack soundproofing qualities. So, replacing them with solid-core doors will enhance the soundproofing effect because they’re denser. Moreover, adding a door sweep can help seal the gap at the bottom of the door.

Decoupled Walls and Ceilings

Decoupling creates a gap between surfaces to stop sound vibrations from passing through. So, using resilient channels or sound isolation clips can help separate drywall from wall studs, serving as another great answer to the question, “How to soundproof a room?” This method is more involved but effectively reduces airborne and impact noise.

Soundproof Curtains

Heavy, dense curtains can help block a surprising amount of noise. So, use them over windows and doorways to dampen external sounds. These curtains are especially useful in bedrooms and living rooms.

How to Make a Room Soundproof from Traffic Noise

Even traffic noise with moderate sound pressure levels (SPLs) affects us negatively. According to researchers Asakura and Tsujimura, household sounds, such as those with much lower SPLs than road traffic noise, can affect cognitive performance. The sound pressure level parameter represents how loud a speaker is.

Learning how to soundproof a room can start by:

• Using weatherstripping or acoustic caulk to seal gaps around windows and doors
• Installing double-glazed windows, window films, or window inserts for better sound insulation
• Using heavy soundproof curtains to absorb sound waves before they enter a room
• Adding acoustic panels to walls to absorb unwanted sounds
• Placing thick rugs or carpets on floors can help effectively absorb sound waves and reduce noise levels.
