Acoustic protection in building installations

The demands on acoustic protection are on the rise. Many building owners and inhabitants are no longer satisfied with the mere observance of minimum requirements in new buildings. Most national or local building codes also offer optional values for increased acoustic protection. A typical maximum value for noises transmitted by building installations in a neighbouring apartment may be around 30 dB(A), whereas increased acoustic protection may be around 22 dB(A).

  

Only mass guarantees genuine acoustic protection

Independent acoustics experts confirm:

The heavier the pipe, the better its acoustic performance!

 

 

Read test reports correctly: watch out for airborne sound level

The airborne sound level is what counts in order to judge the acoustic behaviour of a pipe system or material in comparison with others.

The structure-born sound level, on the other hand, is considerably influenced by the pipe clamps and fixing in the laboratory, which may be more or less practice-oriented.
