Understanding Noise Transmission

Understanding Noise Transmission

If you are living in an apartment building or a multi-story house, chances are you have experienced some form of noise disturbance from the floor above or below you. Noise transmission can be a real nuisance, affecting your daily routine, productivity, and quality of life. Here we’ll go deep into the world of noise transmission and understand its different types and how they affect the soundproofing process.

Impact Noise vs. Airborne Noise

To effectively soundproof between existing floors, it’s important to understand the two types of noise transmission – impact noise and airborne noise.

Impact noise is created when an object hits or strikes a surface, resulting in vibrations that travel through the structure of the building. Common sources of impact noise include footsteps, dropped objects, or furniture being moved.

Airborne noise, on the other hand, is caused by sound waves traveling through the air and penetrating through walls, ceilings, and floors. Common sources of airborne noise include talking, music, and TV noise.

Both impact noise and airborne noise can be a nuisance, and soundproofing methods need to be tailored to tackle each type of noise separately.

Structure-borne Noise Transmission

Structure-borne noise transmission occurs when vibrations from one part of the building structure transfer to another. It is a common cause of impact noise and can be challenging to address as it often requires modifications to the building’s structure.

In the case of soundproofing between existing floors without removing the ceiling, it is crucial to address any potential structural weaknesses that could contribute to structure-borne noise transmission. This can be done by reinforcing the existing floor joists or adding additional layers of mass-loaded vinyl or sound isolation clips to isolate the structure from the vibrations.

Noise Transmission Class (NTC) and Sound Transmission Class (STC)

Noise Transmission Class (NTC) and Sound Transmission Class (STC) are two ratings used to measure the sound insulation performance of building materials. NTC measures a material’s ability to reduce airborne noise transmission, while STC measures a material’s ability to reduce both airborne and impact noise transmission.

When soundproofing between existing floors without removing the ceiling, it’s important to select building materials with high NTC and STC ratings. Mass-loaded vinyl, sound isolation clips, and acoustic sealants are commonly used materials for soundproofing between floors and have high NTC and STC ratings.

Common Soundproofing Materials

Common Soundproofing Materials

When it comes to soundproofing existing floors without removing the ceiling, there are various materials available that can help in reducing noise transmission between the floors. Following are some of the most commonly used soundproofing materials that can be used for this purpose.

Acoustic underlayment

Acoustic underlayment is a type of soundproofing material that is placed between the subfloor and the finished floor. It is made up of different materials such as rubber, cork, foam, or a combination of these materials. Acoustic underlayment helps in reducing noise transmission by absorbing sound waves and preventing them from passing through the floor.

When selecting an acoustic underlayment, consider its thickness and density as it affects its ability to reduce noise. Thicker and denser underlayment is More effective in soundproofing the floors.

Mass loaded vinyl (MLV)

Mass loaded vinyl (MLV) is another popular soundproofing material that can be used between existing floors. It is a heavy and flexible vinyl sheet that is placed on the subfloor or between layers of flooring. MLV works by adding mass to the floor, which helps in reducing noise transmission.

MLV is available in different thicknesses and densities, and its effectiveness in soundproofing depends on the thickness and number of layers used. Ensure that the MLV is installed correctly, as any gaps or holes can reduce its effectiveness.

Green glue compound

Green glue compound is a viscoelastic material that is used in between layers of drywall to reduce noise transmission. It is a non-toxic and environmentally friendly material that is easy to apply. Green glue works by converting sound waves into heat energy, which reduces the amount of noise that is transmitted.

Green glue compound is typically used in combination with other soundproofing materials such as MLV or acoustic underlayment to enhance their effectiveness.

Resilient channels

Resilient channels are metal strips that are installed perpendicular to the floor joists. They help in reducing noise transmission by creating a gap between the ceiling and the floor above. This gap helps in isolating the two surfaces, which reduces noise transmission.

When installing resilient channels, ensure that they are spaced correctly and installed using the recommended screws to ensure their effectiveness.

Soundproofing Techniques

Soundproofing Techniques

If you live in an apartment or a multi-story house, you might be familiar with the problem of noise traveling between floors. It can be a significant source of disturbance and can make your home less comfortable.

Soundproofing between existing floors without removing the ceiling might seem like a daunting task, but it’s not impossible. Below are some effective techniques that can help you soundproof your floors and reduce noise transfer.

Adding Mass to the Floor

One of the most effective ways to soundproof between existing floors is to add mass to the floor. The more mass you add, the better the soundproofing will be. You can add mass by installing a thick layer of plywood or OSB on top of the existing subfloor.

Another option is to use mass-loaded vinyl (MLV) sheets, which are heavy vinyl sheets that can be installed under the flooring. MLV sheets can significantly reduce the amount of noise that travels through the floor.

Creating a Barrier with MLV

MLV sheets can also be used to create a barrier between the existing floor and the ceiling below. To do this, you need to install the MLV sheets vertically along the wall between the floor and the ceiling. This creates a barrier that blocks the sound from traveling through the wall. You can then cover the MLV sheets with drywall or another type of wall covering.

Decoupling the Floor from the Ceiling

Decoupling is another effective soundproofing technique that involves separating the existing floor from the ceiling below. This is done by installing a resilient channel between the floor and the ceiling. The resilient channel acts as a shock absorber, reducing the amount of vibration that travels through the floor and into the ceiling. This technique is particularly effective for reducing impact noise, such as footsteps.

Using Acoustic Underlayment

Acoustic underlayment is a material that is installed under the flooring to reduce noise transfer. It is made from a variety of materials, including cork, rubber, and foam. Acoustic underlayment can be used with a variety of flooring types, including hardwood, laminate, and tile. It helps to absorb sound waves, reducing the amount of noise that travels through the floor.

Sealing Gaps and Openings

It’s essential to seal any gaps and openings in the floor and ceiling to prevent noise from traveling through them. This includes gaps around electrical outlets, HVAC ducts, and pipes. You can use acoustical sealant or foam sealant to fill these gaps and create an airtight seal. This will significantly reduce the amount of noise that travels through the floor and ceiling.
