Acoustics data

Horizontal and vertical measures are necessary to asses the acoustic behaviour of the hollow- space- floor.


Situation:
Concrete ceiling with 16 cm thickness reach a range of running- acoustic of approximately
78 dB.

You achieve an improvement measure   DLw of approximately 10 - 12 dB by using HARBOla- hollow- space- floor and anhydride screed with 4 cm thicknes.

Assessed running acoustic insulating measure


vertical Rw 66 dB
horizontal RLWR 64 dB

Assessed air acoustic insulating measure

vertical Rw 54 dB
horizontal RLWR 54dB

Is anhydride screed with PVC - or parquet used, we achieve additional 2 dB lees.


We are in the common range of 54 dB.Approximately 51 dB are reached by using textile covering.
