Epier des grenouilles avec tissu acoustique 2.0

La grenouille à ventre blanc (geocrinia alba) est une espèce extrêmement petite qui ne vit que dans une zone tout aussi petite. Scientifiques ont découvert que la surface totale occupée par ces grenouilles extrêmement menacées est inférieure à 2 kilomètres carrés de zones marécageuses dans la région de Margaret River, au sud-ouest de l’Australie-Occidentale. Une espèce aussi endémique attire naturellement l’intérêt des scientifiques.

Les biologistes de l’université de Western Australia souhaitaient enregistrer les bruits distinctifs des grenouilles afin de mieux comprendre le comportement de ces animaux. Mais dans un environnement humide, cela pose des problèmes particuliers. Ils ont donc pris contact avec Soundlabs Group à Mittagong, en Australie, notre partenaire de distribution pour la région Asie/Pacifique.

“Mon application n’est probablement pas très conventionnelle”, a écrit Emily Hoffmann, doctorante à l’école des sciences biologiques de l’université de Western Australia. “Je travaille avec des grenouilles en danger critique d’extinction en Australie-Occidentale, et nous essayons de surveiller leur comportement d’appel à distance en utilisant des enregistreurs audio que nous pouvons déployer sur le terrain. J’ai fabriqué des étuis résistants à l’eau pour les enregistreurs audio, mais je dois couvrir les trous des microphones avec quelque chose de résistant à l’eau qui n’interférera pas avec la capacité d’enregistrement.”

Leon Gross, le propriétaire de Soundlabs Group, a été plus qu’heureux d’apporter son aide. Il a fourni aux biologistes une partie de notre tissu acoustique 2.0 hydrofuge. Ce tissu spécialement traité, qui a déjà prouvé ses qualités particulières dans de nombreuses applications telles que les haut-parleurs extérieurs ou la construction de yachts, recouvre désormais la section où se trouve le microphone, de sorte que toute pluie ou goutte d’eau s’écoule sans que la technologie à l’intérieur des boîtiers ni la qualité des enregistrements ne soient affectées.

Church Organ With Acoustic Cloth From Akustikstoff.com

The field of application for our sound transparent fabrics is surprisingly broad. They also play an important role in organ building, for instance. It is quite possible that you will come across products from Akustikstoff.com when visiting a church, for example in Ahaus in northwest Germany. 

The pipe organ, whose roots reach back to antiquity, has played a central role in Christian liturgy since the Middle Ages. Elaborately designed organs are special treasures of numerous churches and impress with their enormous sound variety. Mozart once called the pipe organ the “king of instruments”. Like other instruments, however, organs need regular professional care and occasional restoration. For many parishes such a restoration project is a welcome opportunity to expand and redesign the instrument in order to broaden its musical range and move it closer to modern sound ideals. 

One example is the widely known Church of St. Mary’s Assumption in Ahaus: The local Catholic parish commissioned the old-established organ builder Orgelbau Fleitner from nearby Münster with extensive restoration and extension work. The task was to clean the old parts of the church organ, reassemble them, and make reasonable additions.

A particular challenge for organ builder and voicer Eberhard Hilse, one of the owners of Orgelbau Fleitner, was to harmoniously adapt the appearance of the instrument to the church interior, which dates from the mid-1960s. Hilse chose our acoustic fabric to implement a visually appealing design without compromising its sound and acoustics. 

Completed in February 2018, the three-manual instrument is 9.35 meters high and boasts the impressive total of 2,520 pipes: The swell at the top has 772 pipes, the grand organ in the middle has 840 pipes, the positive behind the console 728 pipes. In addition, there is the pedal with over 180 pipes. The largest pipes belong to the principal 16′, which can be seen at the front of the organ and is assigned to the pedal. The largest of these pipes in the front left with a total length of 664 cm has a diameter of 250 mm and weighs about 105 kg.

Scandinavian Design Meets Our Acoustic Cloth

Excellent workmanship, glorious Scandinavian design, and individual, custom-made production a– that’s what the Danish carpenter Per Plauborg and his company Hifimøbler.dk stand for.

AV furniture from Hifimøbler.dk, with cover fabric from Akustikstoff.comPer’s aim is to make custom-made AV furniture of outstanding quality that meets any customer’s individual taste and demand. All furniture is tailored to the individual customer in terms of color, size, number of shelves, cable holes, and any accessories, such as drawers and legs, wheels, and wall-mounting options. This way, AV furniture from Hifimøbler.dk suits any audio and video equipment and at the same time contributes to an elegant Scandinavian home furnishing style.

AV furniture from Hifimøbler.dk, with speaker fabric from Akustikstoff.comIf you want your Hifi and video equipment as well as similar gear ready for use at all times but still perfectly hidden away in a great piece of handmade design furniture,  Hifimøbler.dk will provide the perfect solution. All furniture is prepared for inside and outside cabling within and between the modules. This way, all cables are hidden, ensuring that the living room always looks tidy and stylish. Even better, these great pieces of furniture come at a price you’d usually expect for standard run-of-the-mill pieces.

Per Plauborg uses fabrics from Akustikstoff.comPer places great emphasis on quality and the compelling craftsmanship of which he is justifiably proud. It’s no wonder, then, that he has chosen fabrics from Akustikstoff.com for the front covers of his furniture. The outstanding acoustic properties of these acoustic fabrics ensure perfect sound reproduction even if the speakers are placed behind the doors. At the same time, the specially designed  acoustic cloth lets infrared signals pass through, so remote controls even work with closed doors.

How to Tell the Quality of Acoustic Fabric

The range of textiles that are offered as speaker cloth or acoustic fabric is almost impossible to grasp, particularly on the Internet. But what makes a true acoustic cloth? Here’s a short quality checklist:

1. Maximum sound transparency

Sound measurements of acoustic fabric from Akustikstoff.comAcoustic information, i.e. sound waves, must be able to penetrate the material as freely and unchanged as possible. Unsuitable fabrics will impair the sound—especially the high and high-mid frequencies—because sound waves are absorbed or diffused. That’s why simple air permeability is no sufficient criterion for the quality of a speaker fabric or acoustic cloth.

Only lab measurements will reveal what a specific fabric is actually suitable for. A direct comparison of measuring results generated with different types of speaker fabric reveals that even a double-layer of standard Acoustic Cloth from Akustikstoff.com is more sound transparent than other polyester or linen fabrics.

By the way: Strictly speaking, fabrics like molleton, which are meant to absorb sound rather than let it through, are not an acoustic fabric but an insulating material.

2. Sufficient opacity

knitting machine for acoustic fabricA good acoustic fabric bridges the physical gap between sound transparency and opaqueness. It will usually be developed exactly for this purpose and produced on state-of-the-art machines, which make an appropriate material structure possible. After all, the fabric is used as speaker fabric, as cover fabric for acoustic elements such as absorbers, diffusers, and bass traps, for AV furniture and instrument amplifiers such as guitar amps, in the car hi-fi sector, and last but not least for cladding in shop fitting, exhibition stand construction, and interior design. Of course, there are physical limits to opaqueness. You can find some more details on this topic here.

3. Elasticity

protoype equipped with speaker cloth from Akustikstoff.comAcoustic cloth requires some tension to ensure an even surface of the cabinet front. That’s why it needs to offer exactly the right amount of horizontal and vertical elasticity. Any fabric that is too elastic will warp during processing and crinkle or buckle after a while. If it’s too rigid, on the other hand, workability will suffer, which can also cause crinkles. Standard Acoustic Cloth from Akustikstoff.com can even be easily stretched around several edges and finally stapled to the frame, as this photo of a model for the speaker cover of a high-end loudspeaker shows. With the topic of stapling we get straight to the next point:

4. Ruggedness

Extra-robust PA-Type Acoustic Cloth from Akustikstoff.comSpeaker fabric is often stretched around hard edges and stapled (watch this tutorial to see how it works), and high-quality acoustic fabrics are durable enough to stand this procedure without laddering or tearing. The weight of a certain speaker cloth usually is a good hint at its stability: Fabrics that weigh between 90 and 140 grams per square metre consist of a single layer of very thin yarn—which puts them close to nylons. No wonder they are similarly sensitive. Akustikstoff.com offers only robust double jersey with a weight of 180 grams or higher per square metre. The particularly rugged PA-Type Acoustic Cloth, which is equipped with a special protective net on the front, even reaches 550 grams without any loss in sound transparency.

5. Even structure

cheap, uneven, lightweight speaker fabricCloseup of Akustikstoff.com fabric







High-quality acoustic fabric is characterised by its even structure. It’s quite easy to distinguish good material from cheap qualities at first sight in direct comparison. Simply have a look at the image: The crinkled fabric on  the left is an imported fabric from somewhere in East Asia. It is offered at prices of about 8-10 euros per square meter by various stores on the Internet and on Ebay without any information about the origin and the manufacturer of the fabric. On the right there’s a photo of the more expensive proprietary fabric made in Germany by Akustikstoff.com–of course taken from the same angle and from the same distance.

6. Flawless workmanship

Faults in cheap speaker fabricAcoustic cloth is a rather delicate fabric, so only high-quality raw materials and perfect processing in all steps can prevent quality defects. And as always, careful processing and consistent, fastidious quality control have their price.
An example of common quality defects are ugly traces of worn needles. Actually, this should be an absolute no-no for any supplier. Such fabrics are clearly seconds that any professional customer will reject. Unfortunately, such defects are quite common with low-cost no-name speaker fabrics such as the budget cloth in our example. Taking a look at the fabric at backlight conditions clearly shows the sloppy work. If you attach some importance to detail in the realm of your hi-fi and AV equipment, you will most probably not be pleased with such speaker fabric.

Uneven colouring due to the use of non-mixed, uncontaminated yarn is another quality flaw that can often be observed with cheap speaker cloth. It is particularly noticeable with dark colours, when somewhat lighter stripes cause an irregular surface. That’s why acoustic fabrics from Akustikstoff.com are exclusively made from high-quality, white polyester yarns.

7. HSE and social responsibility in production

Yarn for Akustikstoff.comAzo dyes, formaldehyde, heavy metals … There’s quite a number of hazardous chemicals that may be hidden in textiles, and the use of some of them is still not sufficiently regulated by law. Even worse, the main reason for the use of these questionable substances, which are still often found in imported textiles, is to ensure cheapest possible production processes. Questions about potential risks for humans and the environment and about the working conditions under which these fabrics are produced are simply ignored. At first glance, the end product may seem “inexpensive”, but closer inspection often brings a different picture to light.
That’s why all fabrics in the product range made by Akustikstoff.com are certified according to the OekoTex 100 standard. This long-established standard contributes to high and effective product safety. The test criteria and limit values often go well beyond the national and international requirements, extensive product controls and regular company audits ensure compliance with the strict guidelines.

Introducing Metallic Line Acoustic Cloth

Metallic Line Akustikstoff - metallic speaker fabricHotter and even more value for money: We’re proudly presenting our new Metallic Line Acoustic Cloth. The new fabric replaces our old “Metal Line” speaker cloth and is readily available in four great colours: Gold, Silver, Copper, and Brass. More colour options will follow suit.

The new speaker grille cloth is made of 100% polyester. Thanks to  an improved production processes, we were able to change the material composition. The new Metallic Line fabrics are made of 100% polyester. This means that our entire product range is now certified according to the German “Oekotex-Standard”, the most valuable eco-seal for textiles and clothing. It will remain our well-kept secret, however, how we achieve the further improved metallic shine.

Even better: The new speaker fabric is even more reasonably priced. The new production process made it possible to produce the speaker grille fabric at a width of 164 centimetres, but  we didn’t change the price per metre. In other words: more value for money per square metre!

Why not have a look at the new products instantly? 

Opacity of Speaker Fabric – Technical Basics and Best Practice

You can’t eat the cake and have it:
Why an acoustically transparent fabric can’t be 100 percent opaque

“Is your Acoustic Cloth really opaque?” That’s a question our customers ask quite frequently. After all,  speaker fabric from Akustikstoff.com is primarily used to hide loudspeakers, AV equipment or whatever else as elegantly as possible without impairing acoustic transparency.

Strong contrast leads to marking with any acoustically transparent fabric.

Marking with acoustically transparent fabric: a deep black background remains somewhat visible under white speaker fabric.

The theoretical ideal is obvious, of course: absolute acoustic transparency plus absolute opacity (i.e., the opposite of transparency) at the same time. Unfortunately, the laws of physics counteract this ideal, since both sound and light are waves – temporal and local periodical changes of a physical quantity in the dry language of physics.


It’s all about waves

As sound propagates through the mechanical deformation of a medium, in our case by changes in air pressure, everything that is in the way acts like a kind of barrier: It is moved itself and starts vibrating, this way absorbing energy from the impinging waves, and it reduces the amplitude, i.e., the magnitude of the oscillation. That’s why a completely closed, airtight surface always attenuates sound waves. Depending on the material, the sound is “swallowed” by resonance and usually reflected or diffused to a certain degree at the same time.

Put the other way round, high acoustic transparency is simply impossible without openings, through which air – and thus the sound – can penetrate. Even the smallest apertures, however, can also be penetrated by visible light, which has a much shorter-wavelength. This effect can be experienced in a striking manner in a completely darkened room as soon as the door does not close completely on all four sides of the door frame.


Crucial: the higher frequency range

Insufficient acoustic transparency is most noticeable in the higher frequencies within the normal range of human perception: the short-wave, low-energy high frequencies and high mids are attenuated first, while energetic, relatively long-wave bass frequencies are noticeably less hindered. In practice, this means that unsuitable or inferior cloth for acoustically active elements usually eliminates exactly those acoustic frequencies that are of utmost importance for a sophisticated, well differentiated sonic image.


Exploring the limits of physics

The secret of high-quality Acoustic Cloth is that it lets sound waves pass through virtually unimpeded but blocks the light waves as much as possible. At Akustikstoff.com, we’ve performed a lot of research and development work to get this physical balancing act done in the best possible way. Nevertheless, it is in the nature of things that both objectives can’t be achieved to the full at the same time. In addition, there’s a third, no less important aspect to be considered in the development of loudspeaker cloth, and we’ve put quite some effort in it: robustness. That’s why all covering fabrics from Akustikstoff.com are remarkably durable and are very easy to process while they feature the highest possible opacity and excellent sound transparency. We’ll go a bit more into details on this in a separate article in the near future.


The opacity of dark speaker fabric is higher than that of brightly-coloured speaker cloth.

In pure incident light, dark colours tend to be more opaque than bright colours. Here in comparison: black and white.

Three typical problems with acoustically transparent fabrics

Typically, problems with the opacity of acoustically transparent covering fabrics occur when there’s a strong contrast between a speaker cloth in a light colour and rather dark objects behind it, when there’s light from behind, and when a source of strong incident light is pointed directly at the surface of the Acoustic Cloth.


Decrease contrast, increase distance

The most important measure to prevent translucency is to keep the contrast between the covering fabric and the objects behind it as low as possible. It is worthwhile, for instance, to varnish the cover frames and fronts of speaker cabinets and sound absorbers, in matt white if they are to be covered with white acoustics.

In addition, a larger distance between the background and the Acoustic Cloth helps prevent translucency. If, however, the speakers installed in a white housing have pitch black diaphragms, these will nevertheless remain visible under most lighting conditions. In some cases, this may even be desired since the effect can also be very elegant depending on taste and design. A similar transparency effect may occur with absorbers: If grey absorber material (think Basotect®) is covered with a piece of white Acoustic Cloth, the surface will often not appear in pure white, but rather in light grey.

Contrast of black and white with speaker cloth

The two pieces of speaker fabric illustrate the intensive contrast of black and white. However, the contrast between black and yellow is even stronger.

Contrast of black and yellow with Acoustic Cloth from Akustikstoff.com

The strongest contrast: black and yellow – in this case illustrated with two pieces of Acoustic Cloth from Akustikstoff.com

By the way, the contrast between black and yellow is even stronger – hence the colour combination of yellow and black for safety markings.


Avoid translucency from behind

A certain degree of optical transparency remains unavoidable if acoustically transparent fabric is exposed to backlight: Similar as with a curtain, the contours – or even more – of objects placed behind a piece of Acoustic Cloth will become recognizable if light is permeating the fabric directly from behind. This problem occurs mainly with AV furniture such as soundboards, soundbars, and lowboards. To avoid this “curtain effect”, place your AV furniture cleverly to prevent daylight from shining through and don’t put any artificial light sources behind the furniture.


Strong incident light leads to transparency

Strong, bundled light that is directed right at the front on the speaker fabric can also lead to transparency effects: The light penetrates the Acoustic Cloth, is reflected by the objects behind the cloth in the opposite direction, permeates the fabric again and this way leads to a certain degree of transparency. Such effects can be prevented by not pointing any light source directly at the fabric, rather using diffuse light, and ensuring a lateral light incident.


Heavy stretching makes speaker cloth increasingly less opaque.

The “curtain effect”: The higher the tension under which the elastic speaker fabric was mounted, the more transparent the speaker cloth becomes. The photo shows a piece of heavily stretched Acoustic Cloth with bright sunlight from behind.

Mind the tension                

The tension that is applied when processing our acoustic fabric is has a considerable influence on its optical transparency: The more intense the elastic fabric is stretched, the wider the meshes become. While heavily stretching a meshed fabric may improve its acoustical transparency (you won’t really need to do this with Akustikstoff.com Acoustic Cloth, as the utmost sound transparency was our primary design objective), it also changes the opacity of the material. This can lead to the so-called “curtain effect”: especially in the case of backlight, the fabric becomes progressively less opaque with growing tension. In such a case, it is necessary to experiment somewhat before final assembly.


Use two layers?

Depending on the application, it may be possible to use two layers of Acoustic Cloth to improve the opacity of the speaker fabric. The acoustic losses, an additional reduction by approx. 1-2 dB at approx. 8-9 kHz, are well within the acceptable range. Even if you use two layers of our Acoustic Cloth, acoustic transparency remains distinctly higher than that of other single-layer materials*. However, it is necessary to work very carefully in order to avoid the dreaded moiré patterns that the fine structures of the fabric may cause when they’re spatially overlapped. To a certain extent, this can be avoided by using the more structured surface of the fabric as the outer side at the front and the second layer with the slightly smoother side outwards. Then twist the two layers of fabric against each other until the moiré effect disappears. Again, some experimenting prior to the final fixation of the speaker fabric will ensure an optimal result.

Musikmesse 2017 – Review

akustikstoff-musikmesse2For the first time ever, Akustikstoff.com took part in the Frankfurt Musikmesse.  Together with the studio builder Professional Media Solutions, we had a share of the joint stand provided by  ES Pro Audio, and we presented our acoustic fabrics to international trade and industry professionals. We introduced six new colours and talked to numerous studio builders, acoustic experts, speaker and equipment manufacturers, stage builders, and, of course, musicians.

The response was consistently positive and encouraging. It confirmed that our range of acoustically transparent fabrics is truly unparalleled worldwide. Professionals were especially impressed by the remarkable properties of our Acoustic Cloth 2.0, which is water-repellent , stain-resistant, and flame-retardant.  Our newly developed PA-Type Acoustic Cloth also attracted great attention – as well as Acoustic Cloth Custom, the custom-dyed speaker fabric that is available in all Pantone™ textile colours starting at as little as one single roll.

Here’s a couple of impressions from the busy days in Frankfurt:

Telephone line fault – but we’re available

Last Friday, storm “Egon” swept across Germany with hurricane-force winds and snow. The storm covered  large parts of Germany with snow, led to numerous flight cancellations, caused power outages – and ruined the telephone line post 500 metres from our  office. In the meantime, Deutsche Telekom started working on restoring the line, but up to now it’s still faulty.

Groomed Again: Lucas PA System Refurbished With PA-Type Acoustic Cloth

First introduced in 1998, HK Audio’s compact and lightweight, yet powerful Lucas system soon became the standard compact PA system for smaller venues. This rugged system still does its job nicely after nearly 20 years.

old-lucas-pa-systemUnfortunately, the foam plastic has started to dissolve and to turn into crumbs on many older Lucas systems.

As you can see on our photo, removing the front grille may reveal everything but a nice view. In this case, the foam plastic crumbs already made their way into the tweeter, so they needed to be removed with a vacuum cleaner.


lucas-pa-system-with-pa-type-akustikstoffAll in all it took less than two hours to make the entire system shine—and sound—in new splendour with our new PA-Type Acoustic Cloth and a few metres of our hook fastener tape.

Now the band that owns the compact PA can start into the new year with a perfectly looking and sounding system. Even better: the Black/Lime Green colour of the acoustic speaker cloth perfectly suits the band’s corporate colour.
