Acoustic Panels for Open-Plan Living Spaces

Open-plan living became the dominant floor plan in European residential construction from roughly 2000 onwards. The spaces look good in estate agent photos and feel cramped and loud in practice. The noise problem is structural: no internal walls means no absorption, long parallel surfaces create flutter echo, and kitchen, living, and dining activity all mix acoustically.

Why are open-plan spaces so loud?

In a cellular floor plan, every room has four walls, a floor, and a ceiling. Some of those surfaces - bookshelves, curtains, upholstered furniture, carpets - absorb sound. An open-plan space with polished concrete floors, plasterboard walls, and a kitchen at one end has almost no absorption. Reverberation times of 1.5-2 seconds are common, and at that level, conversation across a room requires raised voices.

What can and can't acoustic panels fix?

You can fix reverberation by adding absorptive surface area. You can't fix the fundamental noise level from cooking, TV, and conversation mixing - that's a layout problem. The goal is to make the space comfortable at normal conversation volume, which means getting the reverberation time down to 0.6-0.8 seconds.

Where should I add acoustic treatment in an open-plan space?

The dining area is usually the highest priority - the most noise-sensitive activity in the open plan. A wood slat acoustic panel on the wall behind the dining table or on the kitchen wall treats the most used zone. The living area benefits from a panel on the main feature wall or on the wall opposite the sofa.

For large open-plan spaces, aim to treat at least 15-20% of the total wall area. A 30 m2 open-plan space with 3 m ceilings has approximately 60 m2 of wall area - 9-12 m2 of acoustic panel makes a measurable difference.

How do I combine acoustic treatment with interior design?

The advantage of wood slat panels in an open-plan space is that they work as interior design features rather than afterthoughts. A full 3.6 m x 2.4 m feature wall behind the dining area in oak slat reads as a deliberate design decision. The acoustic effect is real - conversations immediately feel more comfortable - but you don't have to explain to guests that you've treated the room acoustically.

WavySlats are particularly effective in open-plan spaces because the three-dimensional profile diffuses sound in multiple directions, which suits the open, multidirectional nature of the space.
