What is Soundproofing?

Sound Absorbers

Sound absorbers are designed to absorb the sound within a room and help to reduce the amount of reverberation or echo within the space.

If you want to soundproof a room as fully as possible, you will almost always need to install both types of sound insulating materials.

How to Control Noise

Before considering soundproofing a building it is worth considering the quality and methods of construction of the building.

There are two main ways to reduce and control noise.

Increasing Mass

The more mass (weight and density) a floor or wall has the less sound will make it vibrate. As a general rule of thumb doubling the mass will give a 5 decibel reduction in the sound transmitted.

Additional Layers

Adding several layers to the construction of a wall or floor can greatly improve the control of noise. Each layer will be made of soundproofing materials, slightly separated to reduce airborne and impact noise transfer.

What is airborne sound & how can you insulate against it?

Airborne sound is sound waves moving around within a space, such as a room. This sound bounces off walls and floors causing vibrations within those surfaces, which will then transmit (re-radiate) to the other sides of the room (receiver space). Often the windows, doors, poorly fitted sockets or any cracks in a wall will drastically reduce its insulation of airborne sound. To reduce the amount or loudness of this sound you need to insulate it with the use of proper soundproofing materials on your walls, floors or ceilings.

Best Airborne Noise reduction products

In order to reduce airborne noise effects you need to add mass to your floors, walls or ceilings, and the most effective way to do that is to add a barrier mat layer to your surface. For floors, this goes above your subfloor, usually concrete or wood, and beneath your underlay.

Please Note: using underlay alone will not be anywhere near as effective as using two layers with a barrier mat underneath your underlay. The barrier mats are purposely designed to reduce noise, whereas underlays are designed primarily for cushioning, warmth and, where necessary, moisture protection.

Barrier Mats for Airborne Noise

CMS WB5CMS 5 2mm barrier mat

Thin yet dense, this makes the ideal product to add mass to your floor without adding unnecessary height, and offers 22dB of airborne noise reduction. Place it beneath your underlay, and above your concrete or wooden subfloor.

CMS WB7.5CMS 7.5 3.7mm barrier mat

Nearly twice as thick as the CMS 5, the CMS 7.5 provides 26dB of airborne noise reduction. Remember, the decibel rating system is logarithmic so a small decibel number increase makes a huge difference. Fitting is the same as above, place it beneath your underlay and above your concrete or wooden subfloor.

SoundlaySoundlay

Available in 2 thicknesses, 12mm for wooden subfloors and 9mm for concrete, Soundlay is the perfect choice if top performance without compromise is your priority. Lay it above the subfloor and beneath your underlay for carpet, and above your subfloor and beneath a layer of plywood, then your underlay for wood, laminate and vinyl.

What is impact sound & how can you reduce it?

Impact sound starts with an activity like a door slamming or heavy footsteps, which then creates vibrations directly through the walls and floors of a building, and the sound travels from one room to another. Impact sound can travel through a concrete floor; from one room to another even if the wall in between is a good airborne sound insulator. To reduce the amount or loudness of this sound you need to stop it at its source with proper soundproofing materials on your walls, floors or ceilings.
