Sometimes you cannot bolt panels to walls. You are renting. You are in a venue hired for recording sessions. You need to treat a room temporarily or reduce a landlord's objections. Acoustic drapes exist for exactly these situations.
A heavy acoustic curtain does something a standard curtain does not: it has enough mass and density to absorb a meaningful amount of mid and high-frequency sound, not just soften slightly at the edges. Hung on a curtain track across a wall, behind a seating area, or to partition a space, acoustic drapes reduce flutter echo and bring down a room's reverb time without a single screw into the wall.
What makes an acoustic drape different from an ordinary curtain
Weight and construction. Standard curtains are too light and too open in their weave to absorb much sound — they mainly block light. Acoustic drapes use a heavy, tightly woven or multi-layer fabric that provides genuine broadband absorption. Some designs incorporate a weighted hem or an integrated backing layer to increase low-end performance.
As a rule: the heavier the drape per square metre, the more absorption it provides, particularly at lower frequencies. A well-specified acoustic drape will typically achieve an αw of 0.40–0.70 depending on frequency and how far it is draped (gathered fabric absorbs better than flat-hung fabric).
Typical use cases
- Rented studios and home recording spaces — add treatment without a permanent installation; take them with you when you leave
- Home offices and video call setups — hang a drape behind your desk to remove the room from calls and recordings
- Churches, village halls, and hired venues — temporary installations for performance, recording sessions, or events where permanent treatment is not permitted
- Windows and glass walls — glass is a near-perfect reflector of sound; drapes in front of large windows address one of the most common problem surfaces in domestic studios and meeting rooms
- Room dividers — hung from a ceiling track, acoustic drapes can partition a larger space and reduce sound travel between areas
Technical notes
Acoustic drapes are measured to BS EN ISO 11654 in both flat-hung and gathered configurations. Gathered drapes (where fabric is bunched to approximately 150% of the track length) consistently outperform flat-hung. αw data is available on request.
Drapes do not provide soundproofing — they do not block sound transmission through walls or between rooms. If your goal is to prevent sound from travelling between spaces, see our Soundproofing section. Drapes treat the acoustics of the room you are in; they do not stop sound from entering or leaving it.
