Sound Insulation Calculator

The Sound Insulation Calculator enables you to easily evaluate the sound insulation between two rooms. The sound reduction between the rooms depends on both the separating wall and the flanking building elements, as all five building elements transmit sound from the source room to the receiving room.

For calculations according to DIN 4109 first the building and the building element must be selected. They determine the necessary weighted apparent sound reduction index R'w for normal sound insulation and, if applicable, recommendations on improved sound insulation.

For calculations according to SIA 181 the exposure to noise caused by the source room and the noise sensitivity within the receiving room must be selected to be able to set the minimum requirements as well as the enhanced requirements for protection against internal noise Di .
