Sound insulation – SIA Standard 181 and DIN 4109

Sound insulation – SIA Standard 181 and DIN 4109


Nowadays, noise is one of the most common forms of environmental pollution. Noise can be quite a nuisance – not just at night when you want to sleep. Noise causes stress, particularly within your own four walls, and noise can even make you ill. Anyone who has ever suffered from poor sound insulation or inadequate vibration isolation knows this.

Protection against noise or sound emissions is therefore becoming an increasingly common issue. Older buildings in particular can sometimes be quite noisy, as sound insulation is often inadequate due to the building fabric and construction methods used in the past. However, the density of development also plays a major role. The closer buildings are to one another, the higher the requirements for sound insulation or vibration isolation.

However, sound insulation and vibration isolation not only protect people, but also machines and buildings. It may be necessary to install machines on vibration-isolated mounts to prevent damage. Vibration isolation of building services equipment or cladding panels almost completely prevents their vibrational movement.

Attention is paid to reducing vibration and structure-borne noise transmission in almost all areas of technology. It has been proven that by using vibration isolation to eliminate disruptive machine or environmental vibrations, precision and work quality in companies are enhanced.
