Can Curtains Improve Room Acoustics?
Curtains and other textile surfaces can influence the way sound reflections are perceived in a room. The result varies with fabric construction, surface area, fullness and the other finishes in the space. Curtains should not be treated as a complete professional acoustic solution in their own right.
Sound insulation and room acoustics are different
Curtains should not be treated like a wall construction that blocks outside noise. Textiles can absorb part of the sound energy reflected by glass, stone and bare walls, which may soften the impression of reverberation. The outcome depends on measured product performance and the room as a whole.
Which curtains may make a greater contribution?
Denser or layered fabrics, greater fullness and a larger covered area generally offer more potential for absorption than a thin fabric held taut. The air gap between the curtain and a hard surface can also influence behaviour. Where a defined result is required, ask for a relevant test report.
Where might the difference be more noticeable?
Textiles may soften the perception of speech and reverberation in living rooms, meeting rooms and hospitality spaces with extensive glazing, high ceilings and many hard finishes. For a significant acoustic problem, curtains should be considered alongside ceilings, walls, floors and furnishings by an acoustic specialist.
