There are many ways to keep chronically stressful noise out of your own four walls. On walls, it is particularly useful to proceed systematically and install insulation. In order to achieve effective noise protection, a few rules must be followed.
Rules for effective wall insulation inside
Insulating a wall extensively against noise is particularly useful for locking out traffic or neighbors' voices. In order to stop the frequencies as effectively as possible, the following rules must be observed:

- Also read - How the noise from an air source heat pump can be dampened
- Also read - Retrofitting a wall for soundproofing wall
- Use insulation materials that are as dense as possible
- work in multiple shifts
- Attach insulation on both sides if possible
- decouple all components from each other
Insulate the outside wall inside against noise
In order to absorb noise from outside, insulation on both sides is usually not possible - especially for tenants. The interior wall insulation should be designed all the more carefully. To do this, heed the other rules listed above as comprehensively as possible.
It is best to plan three layers: a insulation layer and two intent scales. Thus, more frequencies is given space for volatilization than a two-layer construction.
For the insulation layer you use as dense materials as possible as wood fiber, polysterol, cellulose, glass or rock wool (29,80 € at Amazon *) . In the retail trade, you are explicitly found as sound insulation materials reported acoustic insulation panels or. Felt mats. From hard foam plates, for example universal insulation panels made of EPS, see better. They hardly have a significant noise protection performance.
For attachment to the wall, fix wood or metal profiles to serve as a frame for the insulation mats. Important here is to decouple from the wall by insulation strips made of rubber, mineral wool or felt. Otherwise they form unwanted sound bridges to the other components.
You can use simple building boards made of wood or plasterboard for the cladding. As I said, two layers are better than one - at least a few decibels of sound insulation can be extracted from the construction. The same applies to the facing cladding: Avoid sound bridges! So you must not touch each other flat. In order to get a fixation without sound bridges, adjusting swing bars are advisable, which can absorb sound vibrations coming from the wall.
Insulate partition walls
In order to insulate a partition wall inside the apartment against noise from the adjoining room, proceed as described above - only place the insulation construction on both sides of the wall if possible. This enables you to achieve a total sound reduction index of around 47 dB, which corresponds to the second best sound insulation class.
