It seems a minor problem for those who live in the countryside or have a house independent of the city but that of noise is an important and often unsolved issue that could be solved by exploiting tricks for a few euros. Those who live in a condominium, perhaps in the center, know well how important it is to carve out a moment of tranquility away from annoying sounds coming from annoying neighbors or, even worse, from the noise pollution of the streets.

A house in the city has its comforts and it is possible to increase the latter through works aimed at one complete renovation that implement works by sound insulation. Experts in the sector underline that each case is independent and the interventions for the acoustic insulation of domestic environments cannot always solve the problem definitively. In other words, it all depends on some factors, such as the materials used in the construction of the building.

Although there are different regulations that define the minimum requirements forpassive acoustic insulation of a structure (alongside the laws governing noise pollution) recent buildings do not always fully comply with current legislation, appealing more than anything else to a matter of saving on materials. It will then be the responsibility of the owner of one or more properties to face the cost of soundproofing the apartments because, in the end, everyone chooses the company to whom to entrust the interventions based on their budget and the result they want to achieve.

In this context, in fact, isolating a building intended for office use is a very different matter compared to a residential apartment where it is assumed that the tenant spends most of the day, evenings and holidays included. Consequently, the preference for this or that solution is left to free will but in the majority of cases many prefer to postpone the expense.

How much it costs to soundproof an apartment: techniques and materials for greater domestic comfort

To determine which are the best solutions for the soundproofing of the building, it is good to know that noise is transmitted in three ways: by vibrations, by internal movements and by air.

Le vibrations are those sounds, sometimes subtle and annoying at other times deafening and exhausting, caused for example by the engine of an appliance in operation (it can be the air conditioner, a malfunctioning boiler or a washing machine), by the plant of an industry whose establishment it is a few steps from home, from refrigerators or from the lift located near the bedroom. The entity of the sound is perceptible even with the ears plugged since the propagation of the noise mainly affects the building structure.

Some internal movements we have a daily example: the neighbor who moves the furniture, the lady in heels walking around the house, the tenant of the apartment sold who is renovating the interior. They are loud noises, not necessarily continuous but which cause some annoyance if perpetrated during the early afternoon or in the middle of the night.

Finally the noises can be spread to by air: it is the example of the screams of two young people fighting in the street or of the music played at full volume. Also in this case they are sudden and sudden sounds, impossible to tolerate at particular times of the day.


Another element not to be underestimated is to establish which room of the property requires thesoundproofing because it is more sensitive to external noise. Generally there are two (or three) domestic environments that sound badly tolerated and are those rooms dedicated to relaxation and rest of the person: bedroom, study and children's room are the areas that should be isolated with a radical intervention.

Deciding to proceed with acoustic insulation means facing a careful analysis in a sector in which there seem to be many solutions but the final result is little less than satisfactory. The advantages of correct sound insulation they can be multiple, all aimed at the right of each one to live peacefully in their own environments. It will be possible to prevent annoying noises from neighbors but also from the street without advancing the idea of ​​selling off the apartment. It will be necessary to know the materials and proceed with a restructuring that allows a correct acoustic insulation suitable for expectations.

It is good to clarify one aspect: there are solutions soundproofing and solutions soundproofing. Although the two terms seem to be synonymous, only the second is the one indicated for sound insulation. In fact, sound absorption is the ability of a material to absorb noises coming from inside a structure, for example to optimize the acoustics of a room intended for the study of a musical instrument.

The sound insulation is, on the contrary, the ability of a material to isolate sounds coming from the outside, preventing them from spreading inside the home. Of the two alternatives, only soundproofing materials are suitable for acoustic insulation of external noise. On the market there are several panels to be installed inside one or more chambers made of different materials based on natural minerals, vegetable fibers and innovative technologies. The must it is glass wool or rock wool, but also gypsum, cotton fiber and mineral fibers combined with specific resins needed to absorb all types of noise in an optimal way.

In 'acoustic insulation materials they are therefore different from each other and designed to improve comfort inside the rooms. In addition to widely used synthetic products, it is always possible to focus on 100% natural solutions, such as cork. Fully recyclable, low-polluting and with zero environmental impact, cork offers satisfactory results and is an eco-compatible material that meets expectations eco-friendly.

Acoustic insulation can be achieved in different ways, each of which is aimed at reducing the propagation of sounds coming by air, by movement or by vibration. The use of the panels can be considered suitable forwall insulation if you want to drastically reduce the noises produced by vibration. These could come from a railway or even from the appliances in the shop below but, through an intervention  , you will succeed in isolating also the noises of the neighbors.

In view of a energy restructuring of the fixtures you can install soundproof windows and doors with double glasses of which the windows and French windows of many structures are equipped. Someone can even opt for triple glazing but in most cases the structure of the frames is in PVC or aluminum. Wood (a natural material suitable for every aesthetic requirement) is used to define the frame of a window, but what really matters is being able to eliminate any acoustic leak that facilitates the reverberation of sounds.

In other words, it is necessary to equip the windows, doors and French windows with sheaths that seal the doors during the closing of the windows, preventing the thin propagation of the whistles produced by the wind. On the market it is possible to find insulated blinds mainly designed to insulate rooms especially at night: these are products always made with materials such as aluminum, PVC and wood, previously tested to precisely identify the degree of absorbency of each panel.


In fact, any soundproofing work can only be effective following a careful analysis performed by a professional technician in the sector. Someone could turn to DIY using sheaths to optimize the fixtures but DIY is not always the best choice, even more so if you do not have the adequate knowledge on the materials to be used.

Beyond the materials and solutions available on the market, it should be noted that, very often, the noise issue is a factor that can be easily solved by carrying out some types of intervention. Airborne sounds, for example, can be reduced if insulating materials are used for elements such as roller shutter boxes, the frame of the entrance door, the roof which, in some cases, easily absorbs the noise of hail. These are obviously practical and inexpensive systems, to be adopted with the help of an expert and after having carried out an inspection.

restructuring costs for sound insulation vary according to the intervention necessary to optimize the environments, the material to be used and the opportunity to change windows and doors. The expense incurred represents a small amortizable investment both through tax deductions developed by Government, both through an improvement in the quality of life. The law allows to deduct the cost incurred for an amount equal to 50% being able to obtain the facilities on the purchase of materials if the works have been privately carried out. The acoustic improvement must be certified by a technician who will judge the type of intervention carried out as suitable or unsuitable.

One last question must find an adequate answer: how to isolate from the noises of the neighbors? Never heard of the soundproofing of the security door? Most of the annoyances can come from the stairs such as the noise of the lift, the forced closing of the door and the trampling of people climbing the steps. Even the rumor on the landing can disturb and in this regard there are armored doors, with sound insulation certification, able to isolate all the sounds coming from the entrance hall. These are products made up of frames and panels made with specific materials combined with sheaths that seal the door during closing.
