Modules for protection against air-borne and structure-borne sound
The audio box ensures a quiet, relaxed atmosphere even in the case of high volumes and noise interference levels.
The room-within-a-room construction provides all of the prerequisites for this. The walls and ceiling have a high level of insulation against air-borne sound, and the floor has exceptional insulation against structure-borne sound.
Sound vibrations that can enter the building structure play a special role in the reliability of acoustic insulation. This is referred to as structure-borne sound, and can be transmitted via flooring, walls and ceilings and then radiated as air-borne sound in surrounding rooms.
These facts are not always taken into account, because the ear perceives only air-borne sound, and solutions to hinder structure-borne sound require considerable experience and knowledge.
For 25 years, our pioneering constructions have pointed the way to the highest levels of acoustic insulation, and can address all unsolved problems.
Double-shell, acoustically isolated grid modules
These modules take all transmission pathways into account. They are suitable for loud sound sources in normal rooms (with floor loading capacity up to 200 kg/m²), and are used e.g. as practice, teaching, broadcasting and recording booths, as well as for testing and presentations. > To overview of applications
Three aspects guarantee the required insulation reliability:
- The walls and ceiling are comprised of two shells that have no contact with one another or with the building structure. This provides for a high level of insulation against air-borne sound, and an enhanced insulation-weight ratio.
> Measured values for insulation against air-borne sound
- The floor has several layers, including an insulation layer. The level of sound transmission via the floor and ceiling thus remains extremely low.
> Measured values for impact sound level: Sandwich floor
Since in this area every contact can be critical, there are additional acoustic isolation elements which can enhance the insulation against structure-borne sound even further – to the extent that this is no longer a weak point.

Of course the ventilation system, doors and windows provide equivalent soundproofing.
Even with enhanced insulation against structure-borne sound, the modules are suitable for do-it-yourself assembly, and can also be installed on uneven floors (e.g. floors in old buildings or unfinished floors). No permit is required for installation.
Grid modules with further enhanced insulation against air-borne sound
Insulation against air-borne sound can be further enhanced – virtually progressively. The grid dimensions and wall thickness remain the same, as does the flexibility. However, the effort required for assembly and the weight of the construction increase, and a permit may be required.

We will be glad to serve as your planning and contact partner in addressing the question of how your requirements can be met and which room-within-a-room construction is the most suitable.
