The room as an instrument: why acoustics belong to interior design
A room sounds before it is seen. Entering an apartment, you hear its reverberation time within the first second, long before you consciously register the colour of the wall. Hard parallel surfaces of glass, plaster and stone bounce sound back and forth until voices turn sharp and people speak more quietly without knowing why.
A beautiful room in which nobody likes to talk is not a finished room.
In living spaces a comfortable reverberation time lies somewhere between 0.4 and 0.6 seconds. Above that a room turns echoing, below it dull. That range is rarely reached with acoustic panels; it is almost always reached with things that belong in the room anyway: a heavy linen curtain across the full width of a wall rather than only around the window, a thick wool rug with underlay, a sofa in open boucle rather than smooth leather.
Diffusion matters just as much. A smooth empty wall returns sound as one block. An open niche with objects of differing heights, a shelf of books, a woven basket or a rattan chair break that reflection into many small parts. This is precisely why a room with few but textured objects sounds calmer than an empty one.
In practice that means acoustics are decided in the concept, not repaired at the end. During sampling we test not only how a fabric looks but how the room sounds with it. It is the cheapest gain in comfort an interior can offer.
