Do interior design and acoustic insulation work well together?

I would say yes without hesitation, but in this article, no interior design per se. Although, some sound insulation can be very design, this will be the subject of an upcoming article on "interior design and design insulation products".

In this post, we will discuss various solutions in order to have several good ideas of techniques to implement to be quiet at home.

The acoustic insulation can be made of different materials, wood chipboard, synthetic material, cork, mineral fibre etc. You will have to choose according to your ideologies and your budget.

Noise pollution or accoustique disturbance can be caused by several factors outside the building (Planes, trucks, cars, shrapnel) or inside the building (neighbors, plumbing). In addition the noise pollution or accoustique disturbance can be aerial (Music, planes, televisions) or impact (shoes, musical basses, chairs).

There is a solution to every problem. Before I give you a few, let’s take a closer look at what sound is. The unit of measure is the decibel, the particularity of the decibels is that this measure is not cumulative. A drawing is better than a thousand explanations.


Noise pollution can be tackled by several means, the solutions usually have to be combined to obtain a satisfactory result.

This depends on the materials used to build your condo or collective dwelling. The same acoustic or sound insulation techniques will not be used if the construction is made of concrete or if it is mostly made of wood. Keep in mind that the heavier the insulating material, the more it insulates, the more the mass law.

Acoustic insulation of the ceiling:

The best solution is to treat the problem at the source; soil insulation is therefore preferred.

If this is not possible, the installation of plaster board on metal frame or wood is very effective, if you add insulation between the upper floor and the ceiling. For increased efficiency, there are anti-vibration lines that do not transmit shocks to plasterboard ceilings. There are also long-span frames that attach from wall to wall, in this case the ceiling does not transmit at all the vibrations of the upper floor.


Sound insulation of walls:

A quick and design solution is to install heavy curtains against the walls where possible. However the installation of a wall remains the most efficient solution. As I have written above, it is better to use the heaviest possible materials, plaster plate, cinder...

It is also possible to glue a lining complex with embedded insulation. A double wall detached from the wall will be most effective. It consists of two independent walls separated by a spacing that will be filled with rock wool or other acoustic insulation.

Sound insulation by the soil:

Carpeting can reduce noise by 15 to 30 dB. If you don’t like carpet, there are insulating underlayments for floating parquet that are very effective.

Isolate external noises:

To fight against external noises, it is better to isolate the facade from the outside. Insulation of 30 to 35 dB will eliminate most of the nuisances. Windows and doors are the first ones to focus on.

Air seals must be done perfectly because where the air passes, the noise passes. The "air bridges" should therefore be blocked if necessary. In addition, by equipping yourself with asymmetrical double glazing windows, you will divide by 2 the sound level compared to a standard double glazing.

For very noisy environments (close to an airport), you can opt for a double glazing "acoustic sheet" and add a second single window. In this case, 40 dB will be gained.


As a general rule, avoid entry-level materials. They are rarely effective and it is important to take care of the implementation of sound insulation processes, at the risk that they are not efficient.

The idea is to loosen the walls of the ceilings and floors as much as possible to avoid the propagation of acoustic nuisances by the building itself.

For this, resilient layers of materials are the best allies. If necessary, it will be necessary to call on an acoustic expert in building acoustics, who will be able to make a diagnosis and make a complete report on the possible solutions.

If you buy on plan:

You should make sure that your manufacturer is aware of acoustic comfort and that it will comply with the standards in force and therefore your sleep. The simplest way is to ask that the acoustic performance be written on the bill of sale and that an acoustic report be made afterwards, in order to be sure of it.

Finally, the simplest thing to do is not to walk around in shoes in your apartment and place felt tips under chairs and furniture.
