2 Types of Floor Noise to Address

To effectively soundproof tile floors, it’s essential to understand the two primary types of noise: impact and airborne.

Impact or structure-borne noise occurs when an object strikes the floor, like footsteps or furniture being dragged.

Impact noise is typically measured in decibels (dB). According to the Environmental Protection Agency (EPA), noise levels between 40 and 50 dB are generally moderate. In comparison, levels above 50 dB are considered to be loud.

Airborne noise refers to sounds transmitted through the air, such as conversations or music. Soundproofing solutions should address both types of noise to create a peaceful living environment.

We can decrease airborne noise. The most effective way to reduce airborne noise is through acoustic insulation, which absorbs sound waves and prevents them from traveling through the air. According to the US Department of Energy (DOE), adding acoustic insulation can reduce airborne noise levels by up to 95%.

Studies have shown that airborne and impact noise can harm health, making airborne noise slightly more annoying.

According to a study published in Environmental Health Perspectives, exposure to high airborne noise levels can lead to increased stress, sleep disturbances, and other physical and mental health issues.

On the other hand, impact noise has been linked to hearing loss and annoyance due to its higher frequency content.

Acoustic Underlayments

Acoustic underlayments are specially designed to provide superior soundproofing performance. They are typically made from dense, noise-absorbing materials such as cork, rubber, or foam. Installing an acoustic underlayment can significantly reduce both impact and airborne noise transmission.

Underlayment is a crucial component of soundproofing tile floors. It’s a layer of material installed between the subfloor and the tile to absorb and dissipate noise.

Common underlayment materials to Soundproof tile floors include:

  • Foam: Foam underlayment is one of the most popular choices, thanks to its lightweight nature and relatively low price. Plus, it can block both airborne and impact noise.
  • Cork: Cork is an excellent choice for soundproofing tile floors as it’s 85-95% air, giving it excellent soundproofing properties that absorb the noise.
  • Rubber: Rubber provides superior shock absorption, which helps reduce the impact of footsteps. It also insulates the floor from cold air and vibration caused by loud impact noises.
  • Felt: Felt underlayment has many soundproofing benefits, such as foam and cork, with superior insulation to help keep the floor warm.

When selecting a suitable underlayment material, it’s essential to consider the acoustic performance of the material, as well as its functionality. The layer should also be breathable and moisture-resistant to protect the tile and subfloor from water damage. Furthermore, commercial spaces requiring fire resistance should opt for Class A underlayments.

The soundproofing properties of these underlayments are due to their high density and ability to absorb sound waves. The dense layers act as a barrier between the tile and the subfloor, preventing noise from traveling up and through the flooring. Moreover, acoustic underlayments dampen impact noises created by foot traffic and other activities on the tile floor.

Soundproofing Membranes

Soundproofing membranes are thin, flexible sheets of noise-reducing material that can be installed beneath tile floors. They work by decoupling the tile from the subfloor, reducing the transfer of vibrations and noise.

Popular soundproofing membranes to Soundproof tile floors include:

  • Mass Loaded Vinyl: Mass Loaded Vinyl (MLV) is a heavy, durable material and provides excellent noise insulation. It is typically used between two hard surfaces that would otherwise reflect sound back and forth.
  • Acoustic Foam Mat: Acoustic foam mats are effective sound absorbers due to their open cell structure, which absorbs and dissipates sound waves. They are typically used in combination with an underlayment to improve performance.
  • Elastic Floor Mats: Elastic floor mats are shock-absorbing pads designed to reduce noise transmission through the floor by absorbing vibrations. They also protect the tile from impact damage due to furniture or foot traffic.

Acoustic sealant

Acoustic sealant is a silicone-based material used to fill gaps and cracks in the floor. It helps prevent noise from traveling through these areas, which can otherwise act as pathways for sound to travel through. The acoustic sealant also prevents water from seeping into the tile and subfloor, protecting against mold and mildew.

Popular Acoustic sealants to Soundproof tile floors include:

  • Acoustic Putty: Acoustic putty is a flexible, non-toxic material designed to fill cracks and gaps in flooring. It can be used to seal seams between tiles and other flooring materials.
  • Silicone Acoustic Sealant: Silicone acoustic sealant is a silicone-based product that provides a waterproof seal around the edges of the tiles. It also helps reduce sound transmission through the cracks and gaps in the flooring.
  • Acoustic Caulk: Acoustic caulk is a flexible material that can fill small gaps and cracks in the flooring. It helps reduce sound transmission and provides a water-resistant seal around the edges of tiles.
