How to soundproof your floors

Are you looking for ways in which to stop airborne or impact sound from travelling through your floors?  If you are facing the sound of furniture being moved around from the home below you or a kid playing with a football then you are dealing with impact noise.  However if you have a contending battle with a neighbours TV or constantly overhearing your neighbours chatting below then you are dealing with airborne noise.

This article will help you determine what is the best type of soundproofing for your floors to hopefully remove these types of sound.

Are you dealing with airborne noise or impact noise?

AIRBORNE NOISE: This is when the sound travels from the source directly to the recipient of the sound.  This is likely to be through small holes or ceiling cavities.  Airborne noise is typically the sound of a TV, the barking of a dog or loud music.

IMPACT NOISE: Impact noise is caused by the sound vibrating through a surface.  Typically a sound will hit the floor and the impact will cause the noise to vibrate through the structure of the building.  The general path of noise is for it to go to the ceiling of the flat below.  Impact noises are typically the sound of children running across the floor, an item being dropped on the floor or someone playing with a football.

Typically floors are constructed using plasterboard and plaster with timber joints underneath.  Unfortunately this kind of material provides no insulation and does not absorb any of the sound.  This means that both airborne and impact sound can travel very easily from floor to floor and room to room.

How can you stop airborne noise from going through the floor into the ceiling below?

Insulating with acoustic insulation will reduce the impact of airborne sound.  Building regulations advice that 100mm insulation is used but a professional soundproofing company will be able to provide more information on what is suitable for your home or office.  The higher the density of the insulation the less likely airborne noise will be able to travel.  Do not confuse acoustic insulation with thermal insulation which is lower in density meaning it does not cover the same level of sound insulation as acoustic insulation does.

How can you stop impact sound from going through the floor into the ceiling below?

In order to stop the impact noise from travelling you need to effectively reduce the vibration that is caused when an impact sound hits the surface.  How the sound travels will always depend on the force of the impact.

Two types of flooring that are proven to reduce impact noise are acoustic matting and floating floors.  Both of these will reduce the impact but the one that will work for your home or office will depend on the flooring finish you have.

If you have carpet, vinyl tiles, laminate or even solid wood flooring then a professional soundproofing company will determine what soundproofing floor best suits your needs and requirements, ultimately having the highest outcome.
