Examples of sound insulation constructions - Wooden Ceiling

The Phonestar boards can achive good impact and airborne sound improvements.


If you want more construction details, click on the favoured floor installation (e.g. DHG).

The figures below are shown with PhoneStar improved efficiency.


Closed wooden beamed ceiling

DHG DeckeHolzGeschlossen (CeilingWoodClosed)

Output value impact sound L'n,w,R=75 dB

Output value airborne sound R'w,R=46 dB


Visible beamed ceiling


DHS DeckeHolzSichtbar (CeilingWoodVisible)

Output value impact sound L'n,w,R=82 dB

Output value airborne sound R'w,R=26 dB




DHB DeckeHolzBrettstapel (FloorWoodBrettstapel)

Output value impact sound L'n,w,R=76 dB

Output value airborne sound R'w,R=42 dB


Old closed wooden beamed ceiling with plug-in module

DHA DeckeHolzAlt (CeilingWoodOld)

Output value impact sound L'n,w,R=66 dB

Output value airborne sound R'w,R=49 dB

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