Prevent noise hindranceFloor Marcus
Noise is an important topic in society – noise hindrance, in particular. One way to prevent noise hindrance is to insulate your home well. And the proper underlay and flooring make a great contribution to this.
In the Netherlands, the Dutch noise Hindrance Foundation recommends the installation of 10dB-floors (a contact-noise reduction standard) in apartments.
In the Netherlands a decision was made to use a wider frequency range, including the lower tones, so that these lower tones – the kind that penetrate further through a construction – could be measured. This is done by using an index for contact noise insulation. This is ΔIco in which the ‘I’ stands for ‘Index’ and the ‘co’ stands for ‘contact noise’. In this way, a single number can express the positive or negative effects of an underlay in which, according to the Dutch Building Decree, a bare concrete floor must achieve a value of ΔIco=5 dB or higher. (ΔIco is actually equal to ΔLin.) ΔLin expresses the positive contact noise-reducing effects of underlays as compared to the original bare concrete floors. The Dutch standard (NEN) only makes use of this ΔLin.
If you are purchasing/installing a floor, then noise reduction is an important factor to take into account. With the floor configurator at the Homepage, you can quickly select the right underlay with the appropriate noise reduction.
