Soundproofing an enclosure means isolating it acoustically from the outside, which implies a twofold direction:

It is interesting to keep in mind that if the noise level is reduced in one room, it is also reduced in neighboring rooms, although the insulation itself does not improve.

When it comes to soundproofing, we must differentiate between acoustic insulation and acoustic conditioning to use the appropriate materials and techniques in each case:

Something fundamental is to always take into account the type of surfaces to be insulated. An important surface to have good insulation are the walls. To Soundproof a wall we have to focus on its weak points, gaps, openings... which are the places through which sound mostly spreads. Typical openings in a wall are windows and doors, as well as their frames. That is why it is so important that these gaps are perfectly sealed.

The elements that are most used to soundproof environments are: glass wool or cork.

In addition to eliminating or dampening sound waves, soundproofing transforms sound into heat.
