Wooden Ceiling - DHA

Examples of sound insulation construction - DHA

The Phonestar acoustic boards can achievegood airborne and impact sound insulations with the following types of ceilings.

 

 

DHA DeckeHolzAlt (CeilingWoodOld)

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

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

The figure above is shown with Phonestar retrofitting.

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.

Upgrading impact and airborne sound insulation

Further improvements can be achieved through targeted floor constructional systems BHA.
