Noise problems? Learn the art of soundproofing:


Silence is synonymous with comfort in a home, but a very few of those who reside in a city has the privilege of enjoying it. Traffic, machinery, neighbors … In general, we learn to coexist with noise pollution. However, everything has a limit.

European legislation sets the threshold at 65 decibels, from which the sounds that surround us become annoying noise. Local regulations reduce that limit inside a house to 35 decibels during the day and 30 at night. When they are exceeded, our nerves and even our health are affected.

In that case, we should consider a reform to soundproof the house, or at least some rooms. When we speak of soundproofing, we refer to reducing noise to reasonable levels, because it would be difficult and very expensive to carry out total isolation.

The experts of many companies advise, as a first step, to make an acoustic measurement of the house. The annoyance of listening to neighbors is not the same as the constant passage of trains. Each problem requires a proportional solution. Even so, some general solutions can be proposed to achieve greater comfort.

When the noise comes from outside:


  1. Perform an integral work of soundproofing in the exterior walls:

The best insulation, according to experts, is the mass: concrete, cement or brick at least one-centimeter-thick absorb noise very well. Of course, this reform is of great annoyance and has a high price. A cheaper alternative is to take advantage of the air chambers of the facades to fill them with materials that are not sound drivers, such as rock wool, viscoelastic sheets or polyurethane foam.

  1. Place soundproof windows:

Good double glazing (two crystals glued together) or double window (one flush with the facade and another inside the wall). In both cases, they dampen the sound waves and also do not let in the air that transports them.

  1. Strips of cork or rubber for wooden windows:

The objective is to close the space between the window and the frame so as not to let the air pass.

  1. Blinds and curtains:

The fabrics also absorb vibrations. The thicker they are and the more space they cover, the better.

When the noise comes from inside the building:

The pipes, the machinery of the elevator, the television of the neighbors, children, voices … We must locate the focus of these noises to act in the rooms that suffer it, in such a way that the reform is as limited as possible.

  1. Walls:

If they have an air chamber, we can fill it with the insulating materials that we have already seen. If they are little more than partitions, you would have to lift a double wall with insulation or coat it with plates of plasterboard.

  1. Ceilings:

The only possibility is to build a double roof, with a space of between 10 and 30 centimeters between them (the larger that gap, the more acoustic protection we will get) in which an insulating material will have to be placed.

  1. Soils:

Floating platforms are a quick and easy solution: as in the previous cases, they leave a camera between the base and the new floor that reduces noise. The homemade alternative is to place carpets, ensuring that they cover enough space and are thick.

Finally, always take care of the kitchen. Because most of the sound might come from this.  One tip I can provide is if you are going to use a garbage disposal in your kitchen room then don’t forget to check out top rated garbage disposal reviews, because it can help you to select a product which has low sound. Don’t forget to check out the installation tips before buying any of them.
