Noise isolation or as a neighbor with a hammer to beat?

"Buying an apartment, you buy together with her and the neighbors" - popular wisdom, but desperate situations do not happen, and even if your neighbor - a lover indulge in noisy hammer, then there is an exit! This article will tell you about one of the ways to soundproof the ceiling of the apartment.

But to begin it's better with the theory. I promise that it will be a little bit!
In fact, all the materials are applicable for noise reduction in a house divided into two categories.

• 1. Sound-absorbing.
  Such materials have a porous, fibrous, "ragged" structure and soft to the touch. Their operating principle is simple: the sound - a wave - and the materials are first inhibit this wave due to its structure, and then extinguish it completely. By the sound-absorbing materials include: mineral and basalt wool, felt and padding polyester.
• 2. Acoustic.
  It works the exact opposite of the first - insulating materials do not cancel, and reflect sound waves. This dense structure materials: wall panels, bricks, concrete, drywall, to a lesser extent.

Council:
The most effective - to use a kind of sandwich panel
of sound-absorbing and sound-insulating materials at the same time.

Optimal algorithm deal with noisy neighbors is as follows:
- a pre-attached to the ceiling frame of metal profiles or wooden beam fastened insulation sheet (mineral wool);
- top hemming "warmed" the ceiling drywall sheets;
- cover the topcoat.
