lift lobbies/stairwells (communal areas)
The sound absorption level in the communal areas of both new-build and existing residential buildings noise should be sufficient to prevent noise nuisance due to reverberation. A limit of 1.33 seconds is therefore applicable as the reverberation time for frequencies of 250, 500, 1000 and 2000 Hz. Acosorb has a wide range of seamless noise-absorbent solutions, as well as considerable experience in the field of this particular application. We would be pleased to advise you appropriately in accordance with applicable guidelines.
