Sound Absorption

Dwellings

The ceiling of the corridors and the hall will receive an absorptive material featuring an absorption coefficient of 0.70 minimum under 50% of the ceiling surface (note: this is a legal requirement). This can be achieved using acoustic tiles of such acoustic absorption.

Offices

The ceiling of the offices will receive an absorptive material featuring an absorption coefficient of 0.80 minimum under 100% of the ceiling surface. In addition, this ceiling will feature a flanking sound insulation Dncw of 40 dB. This can be achieved using acoustic tiles of such acoustic performances (please note that the flanking insulation of the ceiling is supposed to be inclusive of the ventilation and lighting terminals embedded into it too).

Shops

The ceiling of the public accessible spaces will receive an absorptive material featuring an absorption coefficient of 0.70 minimum under 50% of the ceiling surface (Note: This may be left to the operator’s discretion if it is so stipulated in the leasing contract).
