Noise isolation at home. What to do when the neighbors celebrations do not end

Unfortunately, the insulation of apartments "from the builder" leaves much to be desired. And sometimes the construction of walls and partitions like the old anecdote: "Petrovich, I'm not only hear, but also see." Start searching for the ideal material that will help to get rid of extraneous noise. Alas, it does not exist. But if you look into the heart of the matter, we can make a budget repair and forget about the neighbors.

Before buying materials

Let's "fingers" will understand what is noise. Any sound - a vibration. Vibrating air or construction materials. Our task is to prevent the spread and extinguish this vibration. But not all so simple.

Methods sound suppression depend on their frequency. Conditionally divide the noise in the high frequency ( "air") - a mouse squeak and a low-frequency ( "structural") - blow of the hammer. This is where many make mistakes.

Some materials suppress squeaking others cope with a bang. Therefore, good sound insulation - it is always a system, and the correct choice of materials - half the success. Let's consider a simple example.

Wooden ceiling beams, Rooms 'bottom Rooms' top. Often try to get rid of noise, filling the space between the joists with mineral wool. But it does not work. Minvata well cleans "squeak". But from the stamping and rattling bass music overlap with content.

To get rid of stukturnogo noise, it is necessary to add more dense (heavy) insulator. Was covered with a film of the beam and half covered with sand. We laid on top of mineral wool. The overlap to cope with noise reduction by 100%.

Of course, we have considered a special case of sound insulation. But the example is very simple and intuitive. Frankly, I'm a little uncomfortable when sellers left and right begin vparivat "professional" materials for sound insulation. "Professional" noise-canceling panels, insulation, sound-absorbing screws, sealants, and even tape. What for?

I do not argue, in movie theaters, recording studios, and other such institutions can not do without profsredstv. But in the budget repair is the most common mineral wool + Rooms' gipsum-fiber sheets gives almost the same effect as that of more expensive counterparts. However, provided that the mounting technology.

By the way, inside finishing boards for professional soundproofing is also sand.

Several installation rules

The task is not only to suppress the noise insulation, but also to prevent the spread of noise.

Erecting walls - should be laid between the ceiling and the damping pad. Isolate floor - cut off the noise from the perimeter walls of the room acoustic tape. Erect metal frame for falshsteny - apply dowels with a rubber septum and placed under suspension insulator.
