Noise-Canceling Curtain for €89: Real Effectiveness and Evidence to Be Verified

A noise-canceling curtain for €89: What can you really expect?

A noise-canceling curtain for €89 might seem like a great deal.

The promise is simple: less noise, more peace and quiet, fast delivery, and a very low price. For an online purchase, that’s obviously tempting.

But when it comes to acoustics, a marketing claim isn’t enough. A curtain doesn’t become effective simply because it’s described as “thick,” “soundproof,” or “noise-reducing.” To understand what it can actually do, you need to look at concrete factors: its construction, its weight, the number of layers, the installation conditions, and the available acoustic test results.

Key takeaway:
A low price doesn’t mean a curtain is ineffective. However, a bold acoustic claim made without specifying a testing laboratory, testing standards, test reports, or detailed installation requirements should be approached with caution.

1. The Case of the Checkered Quilted-Lined Curtains

Some low-cost curtains feature a very recognizable design: a decorative front panel, a gray or silver quilted backing—often with a checkered pattern—and claims that they provide soundproofing, light-blocking, and thermal insulation.

This type of product may be a generic imported curtain sold under various brand names, sometimes with very similar designs and highly ambitious claims. A product’s foreign origin is not a problem in and of itself. The problem arises when the acoustic claims are bold, but the technical evidence supporting them is not clearly provided.

Before buying this type of curtain, be sure to check whether the seller clearly states:

the actual shipping location;
the actual delivery time;
the weight of the curtain;
the number of layers;
the acoustic measurement standard;
the laboratory that performed the test;
performance limits depending on the installation method;
return policies, particularly for custom-made items.

2. Can an inexpensive curtain reduce noise?

Yes, in some cases, an inexpensive curtain can provide a little extra comfort. It can make a room feel a bit cozier, improve light blockage, or create a more comfortable temperature near a window.

But that doesn't mean it will deliver true acoustic performance.

To effectively reduce noise pollution, a soundproof curtain generally needs to combine several elements: sufficient mass, a multilayer construction, a large coverage area, proper installation, and as few air leaks as possible around the opening.

A lightweight or purely decorative curtain cannot produce the same results as a textile product designed and tested for acoustic performance.

3. The Problem with Decibel Promises

We often see bold claims such as “up to -20 dB,” “up to -25 dB,” “up to -30 dB,” or “maximum sound insulation.”

The problem is that a single number isn't enough.

To evaluate acoustic performance, you need to know:

which laboratory conducted the test;
According to which standard was the measurement taken;
on which specific product the test was conducted;
in what configuration;
at what frequencies;
whether the test involves a single fabric, a multilayer composite, or a finished curtain;
if the installation conditions are comparable to those of an actual installation.

A decibel figure that lacks an identified laboratory, testing standards, and detailed test conditions should be interpreted with caution.

4. Why the Lab Matters

Proper acoustic performance must be documented.

At Nokomis, our performance isn’t just a marketing claim. It’s based on acoustic tests conducted by the Daidalos Peutz Acoustics Laboratory in accordance with ISO 10140, with a maximum measured performance of up to -28.2 dB depending on the test configuration.

This clarification is important: it does not mean that a curtain will produce exactly the same result in every home. Actual performance depends on many factors: windows, doors, seals, roller shutter boxes, vents, dimensions, side overhangs, height, and the quality of installation.

But this provides an objective basis: the product was measured using a specific method under identifiable conditions. This is very different from a mere, undocumented promise.

5. Weight, layers, and construction are essential

A high-quality acoustic curtain isn't judged solely by its appearance.

Before you buy, check:

the actual weight of the curtain;
the number of layers;
the nature of the textile complex;
the quality of the stitching and finishing;
the final dimensions;
installation recommendations;
the limits clearly specified by the seller.

A simple, thick decorative curtain or a quilted checkered lining can provide comfort, but it doesn't necessarily serve the same purpose as a multilayered curtain designed to improve insulation and soundproofing.

6. The way it's installed makes a huge difference in the result

Even a good curtain loses much of its effectiveness if it's installed incorrectly.

Common mistakes include:

a curtain that's too narrow;
a lack of overhang on the sides;
installation that is too far from the wall;
a large space at the top;
a curtain that's too short;
a Curtain pole fragile or unsuitable;
leaks around the opening.

To improve acoustic comfort, the curtain should cover the weak spot generously. Installation, overlap, and fastening are just as important as the fabric itself.

7. Deadlines and returns must be verified

Price isn't the only factor to consider.

Before buying a curtain advertised as "technical," be sure to also check:

the seller's true identity;
his address;
the actual delivery time;
the shipping location;
return policy;
the availability of customer service;
recent customer reviews;
Consistency between the price, the promise, and the advertised product.

A product that is advertised as high-performing, very inexpensive, and delivered very quickly should be examined carefully.

8. What Independent Customer Reviews Say

Online reviews are no substitute for an acoustic test. They do not technically prove a curtain’s performance. However, they can reveal recurring red flags: longer-than-expected delivery times, products deemed non-compliant, disappointing quality, complicated returns, or difficult after-sales service.

For example, La Maison des Rideaux’s Trustpilot page shows a low TrustScore, and several recent public reviews mention long delivery times, quality deemed to be poor, difficulties with returns, or packages that appear to be dropshipped.

Sound Escape 's Trustpilot page shows a higher overall score, but some public reviews also mention longer-than-expected delivery times or the fact that the products are manufactured and shipped from China—something the customer hadn't clearly anticipated.

Trustpilot notes that the facts described in the reviews are not individually verified. These reviews should therefore be viewed as public customer feedback, not as a definitive legal or technical finding.

9. Pre-Purchase Checklist

Point to check	Why It's Important
Designated laboratory	Indicates whether the performance is documented
Test Standard	Provides a clear framework for measurement
Test Report	Avoid numbers that are purely for marketing purposes
Curtain Weight	Mass affects efficiency
Number of layers	A simple, thick fabric isn't always enough
Rear Lining	A quilted lining is not enough to prove acoustic performance
Installation Tips	Improper installation significantly reduces the results
Actual lead times	Avoid unpleasant surprises
Return Policy	Important if the product is not suitable
Seller Information	Lets you know who you're actually buying from

10. What a noise-reducing curtain can actually do

A well-chosen soundproof curtain can improve comfort in a variety of situations: street noise, a room facing a noisy street, a noisy entryway door, an old window, a picture window, a home office, a feeling of cold or heat near an opening, or a room with too much reverberation.

However, it does not always replace an acoustic window, a soundproof door, comprehensive wall treatment, or a complete professional acoustic treatment.

A sound barrier is a useful solution when noise enters through an opening and the product is suitable for the situation.

11. Why a high-quality acoustic curtain costs more

A more expensive acoustic curtain may include:

a multilayer structure;
heavier fabrics;
a sturdier construction;
appropriate finishes;
standard or custom sizes;
installation recommendations;
documented acoustic tests;
a customer service team that is easy to reach;
post-order follow-up.

Price does not automatically guarantee effectiveness. But an unusually low price should prompt a simple question: What has actually been tested, manufactured, and delivered?

12. Our Approach

At Nokomis, we prefer to clearly state what a curtain can do—and what it can't do.

We do not present soundproof curtains as a magic solution. Our approach is based on a multi-layered construction, measured performance, documented acoustic testing, installation recommendations, and clear information about limitations.

A high-quality soundproof curtain is about more than just price or promises. It is judged by the consistency between the product, the evidence, the installation, and actual use.

Conclusion: What can you expect from a noise-canceling curtain that costs €89?

A curtain that costs €89 can sometimes slightly improve the comfort of a room.

But if it promises a significant reduction in noise without specifying a testing laboratory, without a test protocol, without an acoustic report, without installation instructions, and without clearly stated limits, one should exercise caution.

Before making a purchase, compare the manufacturer, testing standards, weight, layers, dimensions, installation, actual delivery time, return policy, and the quality of customer service.

When it comes to a noise-reducing curtain, the right question isn't just: How much does it cost?

The real question is: What evidence backs up that promise?
