Acoustic Ceiling Systems in Open-Plan Offices: What Architects Need to Know

Open-plan workplaces need more than good design — they need acoustic control. Here’s how Asoft™ PET felt ceiling systems address the performance gap without compromising spatial quality.
The Physics of an Open Plan
Sound in an open plan behaves predictably. Hard surfaces — exposed concrete soffits, glass partitions, polished floors — reflect sound energy rather than absorbing it. Reverberation times increase. Speech intelligibility drops. The subjective result is a space that feels noisy, distracting, and difficult to concentrate in, regardless of how carefully it was designed visually.
Acoustic ceiling treatment addresses this at the source. Introducing sound-absorbing material at ceiling level intercepts sound before it reflects and redistributes, reducing reverberation and improving the overall acoustic environment.
Asoft™ — Material Designed for Performance
NOWN’s Asoft™ is a PET felt acoustic material manufactured from 60% recycled PET content. It achieves True NRC (Noise Reduction Coefficient) ratings up to 0.95 depending on configuration and mounting — competitive with dedicated acoustic treatment while maintaining a clean, refined visual character appropriate for commercial interiors.
The Atmosphera® Ripple ceiling system deploys Asoft™ across a modular baffle configuration. Each module is built to project specification, removing the need for field trimming on-site. The open structure of the system allows straightforward access to services above — HVAC, lighting, AV, and life safety systems can be reached without disrupting the ceiling installation.
Sustainability Without the Caveats
Asoft™ being manufactured from 60% recycled PET is a factual, verifiable material quality — not a positioning claim. For projects targeting LEED v4 Materials & Resources credits, or for clients with documented sustainability targets, this content figure is directly relevant to specification decisions.
Designing for Occupant Experience
Acoustic performance is not a detail to be resolved late in the design process. It shapes how a space actually functions — whether it supports concentration, conversation, or both. A ceiling system that controls reverberation while maintaining architectural clarity does real work. That’s the standard Asoft™ is built to.
