The implementation of mobile screens and Nyquist partitions is a strategic investment in measurable productivity growth and the fulfillment of stringent requirements of the PN-EN ISO 3382-3 standard. Our acoustic systems precisely reduce reverberation time (RT60) and optimize speech transmission index (STI), which translates into real ROI by dramatically reducing distractions in open space areas. The use of ecological PET felt with a high absorption coefficient allows for effective management of sound propagation without costly renovations, while guaranteeing full investment security thanks to certified fire safety certificates (flame retardancy). For architects and property managers, Nyquist systems serve as a tool for flexible spatial design, combining hard engineering data with premium aesthetics. We design partitions with a focus on buildings certified in BREEAM, LEED, and WELL systems, where acoustic comfort is a key parameter of indoor environmental quality. By using high-density materials, our solutions not only provide visual separation but also serve as an effective sound-absorbing barrier, improving speech intelligibility in conference rooms and ensuring acoustic intimacy in focused workspaces.
