With the abundance of solutions for soundproofing, even the paint industry has something to tell.

Noise-canceling paint or soundproof paint has been here for a time to serve as a supplementary solution to noise problems.

Noise Cancelling Paint

Noise is an irritating element that is somehow hard to deal with. That’s why we resort to all kinds of DIYs and practical guides to contain it, whether it is an impact noise or airborne noise.

How can sound deadening paint help? Let’s move on to find the answer.

How is Sound Deadening paint Different from Regular paint?

Sound deadening paint is a unique paint blend with acoustic insulation properties, making it unique from regular paints.

Sounds promising but a little bit problematic because these kinds of mixtures are often hazardous and contain combustible substances.

Luckily, they don’t.

How does Sound Deadening Paint work?

Just like regular paint, sound deadening paint is sound-absorbing paint. It contains special soundproofing fillers that enhance the paint’s sound reduction properties.

These fillers are called ceramic microspheres.

What Material is Used in Sound Absorbing paint?

To achieve the quality of being a sound-reducing paint, noise-canceling paint has ceramic microspheres.

These are fine particles that harden a paint more than the usual, adding strength when applied on drywalls but having lower viscosity when used.

How Does Viscosity have Something to do With Soundproofing?

Low viscosity material means the cavities within that material have wider gaps, making the surface highly porous.

Soundproofing insulation paints have low viscosity, reducing the impact of sound. The fiber in paint distorts the sound waves.

Sound reducing paint is thicker compared to regular wall paint. The sound-absorbing fillers and the ceramic microspheres make the paint substance thicker even if the paint is water-based.

Another property of a sound-absorbing paint is it dries quickly on high-temp space, applicable on any surface, exterior and interior but can dampen unwanted noise.

Pro tip: If your goal is to reduce airborne noise, you need soundproofing materials that absorb rather than block sound.

Where and Where to use the Sound Deadening Spray?

Sound deadening paint also comes in the form of a spray. But this acoustic paint has a particular purpose.

Once applied, the sound deadening spray is resistant to water, ultraviolet rays, and combustion, resulting in an eco-friendly substance but designed for sound absorption and noise reduction.

The sound deadening spray is used for vehicles.

If you recall, sound deadening mats you stick on car surfaces, and the sound deadening spray is a more suitable soundproofing material in liquid form. It is sprayed on certain parts in the car where you want to muffle the sound.

This noise-canceling paint is very convenient if you hate to do soundproofing with acoustic mats.

However, soundproofing spray can only be effective depending on the layer you add and the severity of sound that needs soundproofing. You can spray it anywhere on the vehicle surface where you think it’s necessary.

Parts that need more soundproofing spray are the hood, car window panels, floor, trunk, and those that produce irritating sounds.

Benefits of using noise-cancelling spray over sound deadening mats

  • It gives you less hassle in trimming and positioning mats
  • When touched on the skin, it is easier to remove than the glue or adhesive on mats
  • Can cover all the complicated areas mats cannot

How to apply on cars

  1. Remove the parts covering the surface to paint.
  2. Clean the surface to paint.
  3. Apply the paint spray.
  4. Spray more layers if needed.
  5. Let it dry.
  6. Put the pieces back again.

How Different Frequencies Affect Soundproofing

Understanding the science of sound waves will let you adapt to your soundproofing techniques.

While the sound movement is measured in waves, different sound levels have different wavelengths. Now, each frequency is determined by the type of wavelength they have.

Sounds with longer wavelengths are low-frequency sounds because they travel slower and reach your ears longer than high-frequency sounds.

Pro tip: A sound deadening material is specially made to absorb sound waves. It can eliminate the noise because of the reduced impact of sound waves on the other side of the barrier.

Airborne sound like road noise, conversation, or animal noise have a deeper sound quality, and they are considered low-frequency sound. And these types of sound can be transmitted through a wall panel, ceiling, or floor with greater resonance without soundproofing.

Low-frequency sounds are sometimes more complex to contain due to their richer vibrating effect.

That’s why if you want more effective soundproofing, get a soundproofing material with better acoustic properties. These properties will absorb the sound and thwart the direction of sound waves, decreasing their potency to attenuate to another space.

Pro tip: Frequency is not a measure of sound loudness. Loudness is based on intensity, and it is measured in decibels. So, when a sound is rich in vibration, it means it sends off a high amount of sound energy, giving intensity to the sound.

What Are the Benefits of a Soundproofing Paint?

If you live in a noisy environment, all you want to have is a quiet place as an oasis from a hard day’s work.

Imagine going home with a noisy neighborhood or even family members; silence is the most precious gift at that moment.

Though a lot has been said about soundproofing materials, not everybody has the time to install them. That’s why in the form of paint, you can soundproof your space!

What gain do you have in soundproofing paint compared to conventional tools like acoustic foam or soundproofing foam, acoustic panels, soundproof curtains, acoustic blankets, mass-loaded vinyl, weatherstripping, and many more?

  • It saves you time, energy and is usually a lot cheaper than those mentioned.
  • It works like a standard wall paint but with the quality to ward off the noise.
  • Eco-friendly; doesn’t contain harmful chemicals, doesn’t burn.
  • Provides a thermal insulation sheet.
  • Absorbs sound and reduces echo from medium-frequency sound and vibration from the low-frequency sound. So it works better in muffling late-night conversations from the people next door!
  • Less hassle on adding implements on the wall.
  • Easy to clean with soap and water.

How to Apply Sound Reducing Paint

Applying sound dampening paint is best on drywalls that have airtight surfaces. When added with sound insulation paint, the drywall becomes a solid barrier against sound, just like mass-loaded vinyl does.

Sound deadening paint enhances the mass of the soundproof drywall if done correctly.

Follow these simple steps:

  1. Don’t settle for one layer of soundproofing paint. Add a layer depending on your need. Using a paint roller quickens the pace.
  2. Apply to areas you feel need more soundproofing. This paint applies to ceilings and wood and metal surfaces.
  3. Surfaces with holes must be covered first, and then apply paint over on that cover.
  4. Ensure that the paint is completely dry before applying another coat.
  5. Make the temperature in the room you are painting set high for faster drying. This paint doesn’t quickly dry in a low temp room where there is high humidity.
  6. Sprayed or rolled up, it produces the same quality.


Coating your drywall or car surface with sound deadening paint is another practical way to soundproof your space and avoid the irritating noise.

The paint can only be an effective soundproofing tool if applied correctly.

Whether you have skills in painting, love to do it on your own (to save on labor), or hire a professional, it will create a difference in the sound quality in your room.

Whichever method you choose, noise-canceling paint can be your next friend if you aim to build a quiet environment.
