Acoustic Curtains are commonly applied as soundproof enclosures or soundproof barriers to industrial machines and equipment. Acoustic curtains will help manufacturers and operators of noisy equipment adhere to the government’s regulated decibel time exposure allowance ( 85dBA/8hr ) and thus avoid prosecution, litigation claims and employee harm and discomfort. Tests have also proven that exposure to high noise levels affects concentration, quality of work and willingness to learn.

As well as that, being unable to hear conversation, warning signals or sirens poses a major danger itself. In some cases businesses or construction companies are restricted in the hours of operation because the noise produced affects nearby residents or neighbouring businesses. By installing an industrial sound blanket, companies are able to come under all required government regulation, provide safe and enjoyable working conditions and in turn increase efficiency and profits. As well as blocking sound they can help to reduce and control the spread of dust and fumes. Flexible acoustic curtains are more versatile and economical than rigid enclosures, allowing for easy access or disassembling-reassembling. Soundproof blankets are very durable and can be used in both indoor and outdoor applications and are easily cleaned when soiled.

Visually, there is very little difference between them. At the 27th "Osnabrücker Baumpflegetagen," one of Germany’s most important annual conferences on all aspects of forest husbandry, Empa researcher Francis Schwarze’s "biotech violin" dared to go head to head in a blind test against a stradivarius -- and won. A brilliant outcome for the Empa violin, which is made of wood treated with fungus, against the instrument made by the great master himself in 1711. September 1st 2009 was a day of reckoning for Empa scientist Francis Schwarze and the Swiss violin maker Michael Rhonheimer. The violin they had created using wood treated with a specially selected fungus was to take part in a blind test against an instrument made in 1711 by the master violin maker of Cremona himself, Antonio Stradivarius.

In the test, the British star violinist Matthew Trusler played five different instruments behind a curtain, so that the audience did not know which was being played. One of the violins Trusler played was his own strad, worth two million dollars. ikea anno sanela panel curtainsThe other four were all made by Rhonheimer - two with fungally-treated wood, the other two with untreated wood. 40x64 curtainsA jury of experts, together with the conference participants, judged the tone quality of the violins. ikea akerkulla curtainsOf the more than 180 attendees, an overwhelming number - 90 persons - felt the tone of the fungally treated violin «Opus 58» to be the best. vienna curtains homebase

Trusler’s stradivarius reached second place with 39 votes, but amazingly enough 113 members of the audience thought that «Opus 58» was actually the strad! «Opus 58» is made from wood which had been treated with fungus for the longest time, nine months.ready made curtain kvadrat prijs Judging the tone quality of a musical instrument in a blind test is, of course, an extremely subjective matter, since it is a question of pleasing the human senses. akerkulla curtainsEmpa scientist Schwarze is fully aware of this, and as he says, “There is no unambiguous scientific way of measuring tone quality.” He was therefore, understandably, rather nervous before the test. Since the beginning of the 19th century violins made by Stradivarius have been compared to instruments made by others in so called blind tests, the most serious of all probably being that organized by the BBC in 1974.

In that test the world famous violinists Isaac Stern and Pinchas Zukerman together with the English violin dealer Charles Beare were challenged to identify blind the «Chaconne» stradivarius made in 1725, a «Guarneri del Gesu» of 1739, a «Vuillaume» of 1846 and a modern instrument made by the English master violin maker Roland Praill. The result was rather sobering - none of the experts was able to correctly identify more than two of the four instruments, and in fact two of the jurors thought that the modern instrument was actually the «Chaconne» stradivarius. Violins made by the Italian master Antonio Giacomo Stradivarius are regarded as being of unparalleled quality even today, with enthusiasts being prepared to pay millions for a single example. Stradivarius himself knew nothing of fungi which attack wood, but he received inadvertent help from the “Little Ice Age” which occurred from 1645 to 1715. During this period Central Europe suffered long winters and cool summers which caused trees to grow slowly and uniformly - ideal conditions in fact for producing wood with excellent acoustic qualities.
