Which Noise Can Be Blocked?

Soundproofing your walls can be used to block out a variety of noises. This includes things like traffic noise, loud music, and even conversations.

Depending on the type of soundproofing you choose, blocking out all noises or just certain ones may be possible.

For example, acoustic foam panels effectively block out mid-high-range frequencies, while heavy curtains can absorb low frequency noise. It is important to note that soundproofing materials can only reduce noise levels and not eliminate them.

Therefore, it is important to consider what type of noise you are trying to block when selecting your soundproofing materials.

Types of Noise in A Building

In addition to external noises, various internal noises can be blocked with the right soundproofing materials. These include things like footsteps, furniture movement, and even appliances. Depending on your building type, you may also need to block out noises from other rooms or floors.

For instance, if you live in an apartment building, you may need to consider soundproofing your walls and ceilings to prevent noise from entering your apartment from other units. Similarly, if you work in an office building with many floors, soundproofing can help reduce noise levels between different floors.

No matter what type of noise you are trying to block out, soundproofing your walls can be an effective solution for improved peace.

There are several types of building noise to consider when designing and constructing a building.

Sound can be transmitted through air, water, and solid objects, either airborne or structure-borne.

Sound has three properties: frequency, wavelength, and amplitude, which can be objectively measured using systems of amplitude measurement.

The most common types of sound control for buildings are sound absorption, airborne sound transmission, and impact-sound transmission, which can be controlled using absorbent materials, dense and heavy materials, and de-coupling techniques.

Electrical controls that make arcing, buzzing, snapping, or sizzling noises can indicate a fire risk or an imminent equipment failure.

Adding soundproofing materials to office buildings of all sizes and shapes can ensure greater quiet for staff and help maintain a productive work environment.

3. Create a Caulk Sandwich

To further enhance the soundproofing capabilities of your walls, consider using acoustical caulk to create a “caulk sandwich.”

Apply 3/8-inch-thick beads of acoustical caulk between the two layers of drywall to deaden vibrations and prevent sound from traveling between the walls.

This simple yet effective technique can significantly improve the soundproofing performance of your walls.

However, soundproofing a room with acoustic caulking is a cost-effective way to reduce outside noise by up to 15% [].

Acoustic caulking is more effective than regular caulking because it stays flexible and doesn’t create gaps or cracks that let sound escape.

To soundproof a wall effectively, it’s recommended to use various methods such as weatherstripping, caulking, and insulation to cut down on airflow and seal any cracks that allow sound to pass through.

4. Harness the Power of Mass-Loaded Vinyl

Mass-loaded vinyl (MLV) is a specialized material designed for noise control. It comes in 4-foot-wide rolls and can be hung on walls or installed between layers of drywall.

By sandwiching MLV between the layers of drywall, you can greatly reduce sound transmission through the walls.

This heavy and flexible material effectively absorbs and blocks sound waves, making it an excellent addition to your soundproofing arsenal.

Mass-loaded vinyl is a great option to soundproof a wall from noisy neighbors. Mass-loaded vinyl is a high-density, limp material denser than drywall, and it is used to block airborne noise, such as music playing or street noise.

It is a popular acoustic barrier for soundproofing and has a high STC rating, making it an effective sound barrier.

MLV is versatile and can be used in any soundproofing solution, from professional soundproof studios to home theater rooms.

However, it has limitations and won’t handle structural impact or footstep noise from the above floor. Installing MLV is relatively easy, and it takes as long as it does to install a layer of drywall.

New Walls vs. Old Walls DIY Soundproofing

Soundproofing walls is essential in creating a peaceful and quiet environment, especially in urban areas where noise pollution is high. There are two primary methods of soundproofing walls: old walls and new walls soundproofing. 

Old-wall soundproofing involves adding sound-absorbing materials to existing walls, such as mass-loaded vinyl, acoustic insulation, or soundproof drywall. The process involves cutting holes into the wall and filling them with sound-absorbing material. This method is useful for buildings with historical significance, as it preserves the original structure while reducing noise levels.

On the other hand, new-walls soundproofing involves constructing new walls with sound-absorbing materials. This method is more effective than old-wall soundproofing, as it creates a barrier between the interior and exterior walls, preventing noise from entering the building. New-wall soundproofing is also more flexible, allowing for customizing the wall thickness and materials.

Both methods have advantages and disadvantages, and the choice ultimately depends on the specific needs of the building. Old wall soundproofing is less expensive and preserves the original structure, but it may not be as effective as new wall soundproofing. New wall soundproofing is more effective, but it is more expensive and may alter the appearance of the building. Overall, a soundproofing wall is essential for creating a peaceful and quiet environment, and choosing the right method requires careful consideration of the building’s needs and budget.
