Soundproofing floors from Noisy Neighbours below

 


Separating floors are designed to limit or insulate against airborne sound, such as from speakers and impact sounds such as footsteps. The heavier the floor, the less sound is transmitted. Mass is designed into floors by using concrete or adding layers of dense material to the steel floor structure. The physical separation of a floor reduces the transmission of sound through a structure. The installation of a floating floor, which incorporates resilient layers and uses soft or acoustic floor coverings, is the best option for achieving the perfect soundproofing seal.

 

What is Acoustic Underlay?

Acoustic underlay is specifically designed to help reduce airborne and impact sound within a floor system. It’s used in concrete floors and is great way of reducing impact sound with minimal fuss when it comes to installation. Acoustic underlay is essentially a rubber resilient layer that is traditionally installed underneath the final floor, the flooring from the structure of the building. Acoustic underlayment helps to elevate the floor using a floating floor. The elevation creates a space of dead air that can help to drastically reduce the vibration transmission from one floor to another. Often this type of acoustic underlay is made from recycled wood.

 

How Do Acoustic Underlays Work?

Acoustic underlays are primarily designed to reduce impact sound within a floor system. The purpose of the acoustic underlay is to minimise mechanical fixings and rigid stiff connection between the final floor finish and the structure of the building. Typically, the thickness of the acoustic underlay will dictate the level of impact reduction it can provide, the thicker and more elastic the underlay the greater the impact sound reduction, as the acoustic underlay should act as a spring pushing back against footfall.

 


How to soundproof concrete floors

Concrete floors have a good level of mass and density. This ensures airborne sounds such as talking, and conversation will be blocked. Impact sound such as footfall and moving objects will transfer through a concrete floor. Using a resilient layer such as carpet over the concrete floor is best to reduce impact sound from transferring through concrete flooring. The best way of soundproofing concrete floors to reduce impact sound is to use a layer over the concrete flooring. The soundproof layer is installed over the concrete and below the floor finish. The type of soundproofing you use to block impact sound through the concrete is made from materials that absorb impact sound before it transmits into the concrete. Soundproofing a concrete floor will block impact noise (footsteps) travelling from the room above to the room below. Floor soundproofing can also block airborne noise travelling from below to the room above or from the room above to the room below.

 



Acoustic Foam

The underlayment of acoustic foam tends to be one of the most expensive foam options. This is known to be effective at keeping sound from moving between floors. There are two product types for concrete floors of over screed acoustic underlay and under screed acoustic underlay.
