Special multi-layer construction for optimal acoustic performance
Many mounting systems available
Handcrafted in our in-house sewing workshop in Germany
Effective Reduction of Reverberation Time
Our acoustic curtain STUDIO was specifically designed to meet the highest demands in sound absorption.
Made from two (STUDIO 2) or three (STUDIO 3) layers of extra heavy fabric, the sound is absorbed very effectively down to the low-midrange frequencies, unlike normal curtains.
This special acoustic curtain is ideal, especially in control rooms and spaces with high sound levels, to significantly reduce the reverberation time.
Top Quality
The acoustic curtain is handmade in Germany directly at HOFA. Excellent craftsmanship and high-quality materials ensure that the curtain still looks great even after years of use. The curtain ist available with metal eyelets or curtain tape, hemmed all around, and can be used on both sides.
Acoustic curtains custom-made for you
HOFA acoustic curtains can be custom-made and installed using various mounting systems, for example, in front of windows, doors, or walls. Thanks to our in-house sewing workshop, many sizes and configurations are possible. We are also happy to accommodate personal requests.
Acoustic effectiveness
Our acoustic curtains have the highest efficiency in the mid and high frequencies, which can be enhanced by multiple layers.
Selected fabrics of high weight are used. The acoustic effectiveness, tested by accredited institutes, shows significant sound absorption starting at around 300 Hz.
At 500 Hz, the 3-layer STUDIO acoustic curtain in a gathered state (red curve) absorbs over 80% of the sound energy, while in an ungathered state (blue curve), it absorbs slightly less than 80% of the sound energy in this range.
We recommend a gathering ratio of 2 to 1. A curtain with a width of 200 cm perfectly covers an area of about 100 cm in width.

Frequently Asked Questions about the HOFA Acoustic Curtain STUDIO
What is the HOFA Acoustic Curtain STUDIO and what is it used for?
The HOFA Acoustic Curtain STUDIO is a multi-layered acoustic curtain made of heavy molton fabric. It absorbs mid and high frequencies particularly effectively, thereby significantly reducing the reverberation time in the room. This improves room acoustics and creates a more pleasant, quieter sound environment.
The Acoustic Curtain STUDIO was developed for use in recording studios, but is also suitable for many other areas – for example, living spaces, offices, hi-fi rooms, or home cinemas. It can be installed in front of doors, windows, and passageways, and can generally be used as a large-area absorber.
If, on the other hand, your main focus is sound insulation and the acoustic separation of areas, the HOFA Acoustic Curtain ISO is exactly right for you.Â
What materials are HOFA Acoustic Curtains ISO made of?
HOFA Acoustic Curtains STUDIO consist of multiple layers of heavy cotton molton fabric. The sound-absorbing molton layers primarily reduce mid and high frequencies.
The curtains are available in the following variants:
| Variant | Layers | Basis weight |
|---|---|---|
| STUDIO 2 | 2 layers fabric | 600 g/m² |
| STUDIO 3 | 3 layers fabric | 900 g/m² |
Additional layers are available upon request.
What is the absorption coefficient of HOFA Acoustic Curtains STUDIO?
HOFA Acoustic Curtains STUDIO absorb mid and high frequencies particularly effectively, thereby significantly reducing the reverberation time in the room. In a gathered state, the 3-layer Acoustic Curtain STUDIO achieves an absorption coefficient of over 80% at around 300 Hz – this corresponds to a sound absorption coefficient of α > 0.8.
How do I achieve the best results when using a HOFA acoustic curtain?
For optimal results, the curtain should not be pulled flat, but mounted with sufficient gathering. We recommend a fullness ratio of 2:1. This means: a 200 cm wide curtain covers a width of approximately 100 cm.
How do HOFA acoustic curtains differ from conventional curtains?
HOFA acoustic curtains are specifically developed to improve room acoustics. Unlike conventional curtains, they consist of particularly heavy, multi-layered fabrics that absorb sound much better. As a result, they reduce the reverberation time in the room and create a more pleasant, quieter sound environment.
One difference between HOFA acoustic curtains and many acoustic curtains from other manufacturers is the significantly higher surface weight and the effective material. Lightweight curtains with low material usage usually have only a limited acoustic effect. For a noticeable reduction in reverberation or noise, a high surface weight, a suitable multi-layered structure, and proper installation are crucial.
HOFA acoustic curtains are also available in two variants:
The HOFA Acoustic Curtain STUDIO is developed for maximum reverberation time reduction and has a high absorption coefficient.
The HOFA Acoustic Curtain ISO combines reverberation time reduction with sound insulation, and thanks to the integrated ISO foil, it has excellent sound-insulating properties.
Can the curtain be equipped with an additional outer fabric or edge and grip protection?
Yes, we are happy to supply your curtain with custom edge protection or grip protection. We use durable synthetic leather in the color of your choice as the material. Additionally, we can use your preferred fabric as an outer layer.
You can design a curtain with edge or grip protection according to your preferences in our Acoustic Curtain Configurator.
For custom outer fabrics or any other requests, please contact us directly.
Does the HOFA acoustic curtain also have a blackout effect?
Yes, thanks to the thick layers of fabric, HOFA acoustic curtains also have a darkening effect.
For particularly high levels of blackout, we can equip your acoustic curtain with an additional dimout layer. Please use our Acoustic Curtain Configurator for this.
Does the curtain also protect against heat and cold?
Yes, due to the number of layers and the thick molton fabric, the curtain also ensures that the warmth stays in during the winter and the heat stays out in the summer.
How are HOFA acoustic curtains mounted, and where can I get the appropriate mounting hardware?
HOFA acoustic curtains are manufactured with either eyelets or curtain tape. Curtains with eyelets can be hung on a matching curtain rod. Curtains with curtain tape are suitable for mounting on a curtain track.
You can get the appropriate accessories for wall or ceiling mounting directly in the HOFA Shop or the Acoustic Curtain Configurator. There you will find various curtain rods, curtain tracks, and other mounting hardware. If you have any questions about the right fastening, we will be happy to advise you personally.
Are HOFA acoustic curtains flame-retardant?
The curtain is made of flame-retardant materials in accordance with DIN 4102/B1. For further details, please contact us.
Where are the HOFA acoustic curtains manufactured?
HOFA acoustic curtains are manufactured in our own sewing workshop in Southern Germany. Through regional production, we avoid long transport routes and can produce in a particularly resource-saving manner.
Another advantage: We manufacture the curtains individually according to customer requests. This allows us to flexibly accommodate custom sizes and special requirements.
