Examples of sound insulation constructions - Solid Ceiling

The Phonestar boards can achive good airborne and impact sound insulation improvements on concrete ceilings.

Solid ceiling

DM DeckeMassiv (Solid Ceiling)

Thickness 180 mm

Output value impact sound L'n,w,R=73 dB

Output value airborne sound R'w,R=53 dB

The figures above are shown with PhoneStar improved efficiency.

The specified panel thickness are calculated without the final covering. 

Please consider the notes at the end of this chapter.

The specified impact and airbone sound insulation are primarily a comparison of the installations and may vary in individual cases.

 

* Please note the following information of the given sound insulation datas and other techincal

  specifications.

 

Note:

If there are high airborne sound insulation datas of the construction and low impact sound pressure levels which are measured in the underneath room, the sound insulation will be better.
