Rideau absorbant acoustique, phonique et insonorisant, anti et coupe bruit
L’intérêt de cet article est de comprendre l’intérêt d’un rideau absorbant acoustique, phonique et insonorisant.
You'll learn more about its noise-canceling and sound-dampening effects.
Why use an acoustic curtain?
Decorative elements and furniture such as sofas, rugs, carpeting, and curtains can provide acoustic comfort. The advantage of an acoustic curtain is that it is the only piece of furniture that can be placed in front of a window or a picture window. Glass, even though it provides plenty of light, is an inert material that significantly contributes to a room’s resonance. In certain settings, such as schools, open-plan offices, or standard offices, windows make up a significant portion of the “wall” surface area and should be addressed. Curtains can thus help regulate sound propagation within a room.
Comment savoir si un rideau phonique et anti bruit est efficace ?
Rideau acoustique et phonique, quelle efficacité ?
Dans le marché du rideau acoustique, l’amalgame est souvent fait entre isolation phonique et acoustique.
Les rideaux sont parfois vendus pour avoir la double fonction.
L’isolation phonique consiste à ne pas laisser « entrer » le son extérieur d’une pièce dans celle-ci. Le traitement acoustique consiste à réduire les échos et la réverbération d’une pièce.
Les rideaux acoustiques sont souvent vendus pour obtenir des gains d’isolation phonique, avec des réductions de bruit entre 5 et 18db.
A gain of 5 dB is relatively small, whereas 18 dB provides a real solution, and the difference will be clearly noticeable. For example, a standard interior door already offers sound reduction of between 18 and 27 dB.
It’s important to understand that this reduction in decibels varies depending on the frequency. Depending on your situation, it may be better to choose a curtain that performs well at mid and high frequencies. For others, however, it may be preferable to have a curtain that performs well at mid and low frequencies.

. It is always a good idea to identify the types of noise that bother you so you can choose the best solution. To better understand this, take a look at the graph below.
En plus de ce gain de réduction de bruit de l’extérieur vers l’intérieur (isolation phonique), les rideaux offrent une absorption acoustique. Ceci, bien souvent, car leur conception est effectuée avec des matériaux textiles en différentes couches. Ainsi, ces matériaux en combinaison avec un plénum d’air, permettent d’offrir un amortissement acoustique.
These two factors therefore offer a significant benefit in terms of a room’s acoustics.
However, it should be noted that curtains—even the best ones—are often used as supplementary or finishing touches in an overall design project.
This is mainly becausea curtain only works when it is closed in front of the window.
However, in spaces with many windows or floor-to-ceiling windows, the goal is to let in more light and open up to the outside… which is the exact opposite of what curtains are meant to do.

Efficacité : déterminer le meilleur rideau phonique
Acoustic curtains reduce noise through two main operating principles.
First, in terms of sound absorption: the curtain is made of thick, dense fabric, which absorbs sound due to its thickness and the air pocket it creates.
The second is based on the mass-spring effect: the curtain consists of successive layers of different materials that work together to optimize sound absorption. One layer absorbs sound, another reflects it…
The following points should be noted:
The thicker the curtain, the better it works
The farther the curtain is from the support, the better it works
The more surface area the curtain covers, the better it works
There are several types of acoustic curtains:
The conventional curtain
The Japanese-style fabric curtain
Curtains that provide good soundproofing are often:
Techniques consisting of multiple layers.
Occultant
Thick
Heavy
Away from the wall
Made of natural felt
Velvet
Rideau épais anti bruit et isolation phonique
As mentioned earlier, the thickness of the curtain will affect its sound-absorbing properties. It is therefore bestto use a thick curtain and pay attention to the material used. Test reports can also provide additional insight into the product’s quality. However, they should be examined with particular care. We will return to this later.
Rideau phonique et anti bruit, quel gain de décibels espérer (12 db, 20 décibels, 21db ou 30 db) ?
Un rideau relativement basique va permettre une réduction de l’ordre de 5 à 7db. Ceci correspond à la réduction standard d’un rideau dit acoustique. Ces rideaux sont soit relativement épais, soit composé d’une fine couche de tissu « métallisé » comme pour les isolants de garages. Un rideau de meilleur qualité aura des performances comprises entre 12 et 18db. Ces rideaux seront pourvus de plusieurs couches. Certains seront très lourd et épais car ils sont composés de tissus de qualité, et combinés à des feutres ou des molletons. D’autres, qui font l’objet d’une attention particulière, peuvent rester légers grâce à une recherche sur les matériaux et la technicité. Ils sont composés de textiles lourds, d’enductions, de feuilles métallisées et de molletons. Rideau isolation phonique 5 et 7 couches : performance acoustique et anti-bruit Les rideaux phonique techniques, acoustique et anti bruit peuvent ainsi intégrer 5 voire 7 couches !
The more layers the curtain has, the more effective it will be (depending, of course, on the materials used). However, it will be heavier and, as a result, less easy to handle.
In addition, because of its properties, a noise-reducing curtain will also significantly reduce reverberation in the room. However, in this case, the curtain must be kept closed at all times!

Les usages d’un rideau phonique et acoustique
L’acoustique est importante dans de nombreuses situations. En ce sens, des rideaux peuvent être utiles pour une maison ou un professionnel. Rideaux pour isolation phonique Comme expliqué précédemment, un rideau apporte un renfort en termes d’isolation phonique. Ainsi, il peut vous aider à passer des nuits plus sereines si vous êtes proches d’une route. Mais il n’empêchera pas d’entendre la fête qui se passe chez votre voisin.

Acoustic curtain for a studio
An acoustic curtain is also very useful in a studio:
Whether it's an apartment
Or whether it's a music studio
In fact, acoustics offers numerous benefits for both of these environments.

The price of soundproof fabric per yard
As with many acoustic products, thinking in terms of price per square meter is of little use. It is better to consider other factors, particularly acoustic performance per square meter, when comparing products.
On top of that, just like an acoustic panel, an acoustic curtain is more technically complex than it appears. Having one custom-made by an upholsterer would cost you significantly more than buying a ready-made one.
Rideau phonique et anti bruit pas cher : quel prix mettre ?
The price will depend on the results you’re looking for. As is often the case, curtains are available at every price point. The least expensive options range from €90 to €129. However, professionals don’t generally recommend them because they aren’t very effective. A high-performance acoustic curtain can cost between €250 and €600 per panel.
Alternatives to soundproof curtains from Galon, Moondream, IKEA, Leroy Merlin, Castorama, and Amazon As mentioned earlier, the number of layers and the construction of a curtain will affect its performance. The problem is that most of these sites offer basic curtains. If you look at most customer reviews, you’ll see thatthe effectiveness of these products is quite mixed. This is reflected in the price: it is indeed low. As is the case in many markets, you therefore need to spend a certain amount to get a decent result.
De même, si vous achetez ce type de produits dans un projet global que ce soit pour de l’isolation phonique et du traitement acoustique, la mise en œuvre est primordiale. Elle nécessite les conseils d’un expert, chose que vous ne trouverez pas sur ces sites.

Limitations of the acoustic curtain
Rideau et performance phonique
Nous avons traité la question au début de cet article. Comme indiqué, un rideau n’a qu’un intérêt limité pour de l’isolation phonique.
The problem with an open curtain
The problem with acoustic curtains is that they are often left open. However, they are inevitably more effective when closed, as they cover a large area. This is especially true since, in most cases, they cover highly reverberant surfaces (such as floor-to-ceiling windows). These surfaces will have a negative impact on your acoustics.
Test reports
It is important to be cautious about the sound pressure levels of acoustic curtains. You should also be careful about the methods used to calculate noise reduction with these curtains. In fact, many products are marketed with an “NRC” rating. It is presented in the same way as the “Aw” rating. However, technically, they are not the same thing.
Ideally, therefore, you should have a complete alpha-Sabine test report, broken down by frequency. It is therefore preferable to calculate the gain index in terms of the reduction in RT (reverberation time) with the curtains open. In practice, they are more often open than closed, so the treated surface area is not the same.
In addition, as mentioned earlier, a curtain must be closed to be fully effective.
Also keep in mind that sheer, see-through curtains don’t work. As a result, you lose the appeal of your windows.
In conclusion, acoustic, soundproof, and noise-reducing curtains: what should we make of them?
Soundproof curtains can therefore be useful for improving your acoustics. To be effective, they must be “open,” that is, unfolded. They can be used in many situations. Their performance depends on their thickness and how they are installed. While test reports are a useful indicator for forming an opinion, it is essential to examine the testing method to ensure that the performance results have not been exaggerated by the testing process.
