Acoustic Panels or Soundproof Curtains: What to Choose Against Noise
Acoustic panels and soundproof curtains do not solve the same problem: the panel, fixed to a wall or ceiling, absorbs reverberation inside a room and reduces echo, while the curtain, hung at the window, attenuates noise coming from outside and also absorbs part of the resonance. The right choice depends on the source of the nuisance: indoor echo or outside noise.
The Kurtens 3-in-1 curtain, 620 gsm, attenuates up to 22 dB* at the window, the main entry point for street noise. Adjustable and decorative, it acts where the acoustic panel does nothing against outside noise.
Two different problems: indoor echo and outside noise
Acoustic panels and soundproof curtains are two distinct tools. The panel, fixed to a wall or ceiling, absorbs echo and reverberation inside the room. The soundproof curtain, hung at the window, attenuates the noise that comes from outside and dampens part of the resonance. Absorbing ambient sound and preventing its transmission are two different functions.
Before choosing, ask yourself a single question: does your room echo and the reverberation disturbs conversations, or is it a noise from outside, traffic or neighbours, that bothers you through the window. The answer points to the panel or to the curtain.
The acoustic panel: absorbing echo indoors
The acoustic panel is an absorbent element fixed to a wall or ceiling. Its role is to reduce a room's reverberation time, and therefore the echo, to make speech more intelligible and the sound clearer. It is the right tool for a home studio, a meeting room, an open office or an empty, echoing room.
Its limit is clear: it does not block noise coming from outside. A panel on the wall will not stop the street from being heard through the window. It is also a fixed, visible installation that takes up wall space and cannot be modulated.
The soundproof curtain: acting at the window, the noise entry point
The window is the weak link of most rooms against outside noise. The soundproof curtain acts precisely there: a dense fabric adds mass in front of the glazing and attenuates the noise passing through it, while absorbing part of the room's reverberation thanks to its textile layers. It therefore provides both a little insulation and a little absorption, with no wall installation.
The curtain does not replace a full studio acoustic treatment, where panels remain essential. But for the everyday need, reducing street noise and softening a room that echoes, it offers the best compromise, adjustable and decorative. Discover the custom soundproof curtains collection.
Comparison table: acoustic panels or soundproof curtains
Each excels on its own ground. Here is the honest comparison.
| Criterion | Acoustic panel | Kurtens soundproof curtain |
|---|---|---|
| Indoor echo and reverberation | Very effective | Partial |
| Noise from outside | No effect | Attenuated, up to 22 dB* |
| Installation | Fixed to wall or ceiling | Rod, no drilling |
| Adjustable | No, fixed | Yes, open and close |
| Extra benefits | None | Thermal, blackout, decor |
*Data obtained under optimal test conditions. Real attenuation depends on the noise, the window and the fitting.
When the panel, when the curtain, when both
The acoustic panel is the answer when the problem is indoor echo: an empty room that resonates, a recording studio, a meeting room where people struggle to understand each other. The soundproof curtain is the answer when the nuisance comes from outside, through the window, and you also want an adjustable, decorative, no-works solution. In a room that has both problems, echo and street noise, the two complement each other: panels on the walls, curtain at the window.
Be careful not to confuse the tools. If your question is about the difference between a soundproof curtain and an acoustic curtain, two types of curtains rather than a wall object, see our dedicated article on soundproof or acoustic curtains. And to choose the right insulating curtain, see how to choose a soundproof curtain.
Density makes the curtain's performance
Not all curtains are soundproof: it is the mass of the fabric that attenuates noise, following the mass law. Below 300 gsm, the effect is almost nil; from 500 gsm, the attenuation becomes noticeable. The Kurtens 3-in-1 curtain, at 620 gsm and three layers, attenuates up to 22 dB* at the window. Cut to measure, it covers the whole opening and removes sound leaks on the sides, where a standard curtain that is too narrow lets noise through.
The Kurtens soundproof curtain
The Kurtens 3-in-1 curtain is the brand's most soundproofing model. It combines three technical layers, weighs 620 gsm and attenuates up to 22 dB*, while blocking 100% of light and insulating thermally. Hung on a rod, with no drilling, it acts at the window against outside noise and softens the room's reverberation, without taking up wall space or requiring a fixed installation.

Frequently asked questions
Does an acoustic panel block street noise?
No. The acoustic panel absorbs reverberation inside the room, it does not block noise coming in through the window. For outside noise, it is the soundproof curtain at the window that acts, by adding mass in front of the glazing.
Does a soundproof curtain replace acoustic panels?
For a full studio treatment, no: panels remain essential to control reverberation. But for the everyday need, reducing outside noise and softening a room that echoes, the dense curtain is often enough, with the advantage of being adjustable and decorative.
Is an acoustic panel fixed to the wall or the ceiling?
Both. The acoustic panel is fixed to hard surfaces (walls, ceiling) to absorb the room's reverberation. It is a fixed, visible installation, unlike the curtain, which hangs on a rod at the window and can be opened or closed. The panel only treats indoor echo, not the noise that enters through the glazing.
What solution for a room that echoes?
If the problem is echo in an empty room or a studio, the acoustic panel on the wall is the right tool. Dense, large curtains also help dampen reverberation, but for precise control of a room's acoustics, panels remain the reference.
Can panels and a curtain be combined?
Yes, and it is often the best approach in a room that has both indoor echo and outside noise: panels on the walls for absorption, a soundproof curtain at the window for outside noise. Each handles what the other cannot.
What curtain weight to attenuate noise?
Below 300 gsm, the acoustic effect is almost nil. From 500 gsm, attenuation becomes noticeable. The Kurtens 3-in-1 curtain, at 620 gsm and three layers, attenuates up to 22 dB*. It is density, and a made-to-measure sizing, that make the performance.
Key takeaways
Acoustic panels or soundproof curtains, it all depends on where the noise comes from. The panel absorbs echo indoors but does nothing against outside noise; the soundproof curtain acts at the window, attenuates outside noise and softens reverberation, with no wall installation and in an adjustable way. For a studio, panels remain essential; for street noise and the comfort of a living space, the dense curtain is the best compromise. The Kurtens 3-in-1 curtain, 620 gsm and up to 22 dB*, is cut to your exact dimensions. Configure yours in the custom soundproof curtains collection.
