Horizontal and vertical measures are necessary to asses the acoustic behaviour of the hollow- space- floor.
Concrete ceiling with 16 cm thickness reach a range of running- acoustic of approximately
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
Assessed air acoustic insulating measure
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.
