System 7400 Acoustic wall

Fully-glazed wall

Acoustic absorbers

The transparent glass acoustic wall system 7400, which provides highly effective soundproofing within the room, is designed for use within open-plan office spaces. The combination of room-height glass elements with wall-mounted and ceiling-mounted absorbers makes it possible to create acoustically independent zones. These permit a reverberation time that is appropriate for the activity and provide areas to conduct confidential work with standardised sound level differences of up to Dn,T,w 27 dB. The feel of the overall space remains unchanged thanks to the discreet design of the absorber surfaces.

The system partition wall prevents any direct transmission of sound between adjacent workspaces. The micro-perforated absorber elements are configured for human speech levels and have a special layered structure. As a result, they can cover a wide frequency range of between 100 and 5000 Hz. Closed-off corridor walls and doors are intentionally omitted. The correct combination and arrangement of the glass acoustic wall system 7400 enables a tailor-made acoustic concept to be implemented for any open-space environment.
