Sound insulation

Sound insulation for doors and windows is becoming more and more important. Almost every day we are exposed to all kinds of noise, which is not only annoying, but can also affect our health.

Sound insulation

Almost everyone is affected by noise pollution these days. A survey by the Federal Environment Agency shows that more than half of the German population feels disturbed by road traffic noise. Noise is not only annoying but can also affect your health in the long term because restful sleep is essential to healthy living. Whether you live beside a motorway, have noisy neighbours, are exposed to heavy flight or rail traffic noise or have children who are up-and-coming drummers: there are sound insulation options for every living situation. We will show you which sound insulation products are the right ones for you.

What are the sound insulation requirements for a music school?


Definition of noise

Noise is measured in dB A (decibel A), which is not the absolute volume but the so-called sound pressure level. As a rule of thumb: if the sound pressure level is reduced by 10 dB(A), noise is perceived as only half as loud. Heavy truck traffic, for example, has a sound pressure level of about 90 dB(A) and is perceived as very unpleasant. The sound pressure level of normal road traffic is approx. 80 dB(A) and is perceived as much quieter. While there is a noise level of 40 dB(A) in the living room, the sound pressure level in the bedroom is slightly above 20 dB(A).

How loud is it in Germany?

Noise map – Day

Noise is perceived as a nuisance if the outdoor level is above 40 dB(A) at night and above 50 dB(A) during the day.

Noise map – Night

Noise is perceived as a nuisance if the outdoor level is above 40 dB(A) at night and above 50 dB(A) during the day.

According to the Federal Environmental Agency, one in five people is negatively impacted by noise from railway, street and flight traffic with a sound pressure level exceeding 55 dB during the day. During the night, one in eight people are disturbed in their sleep by traffic noise of over 50 dB(A) - not counting loud neighbours or strong background noise in their buildings. People living in Berlin, Bremen and Hamburg are the most severely affected. The noise map shows very clearly: in order to protect our health, sound insulation measures are required.
