Get Noise Blocking Curtains For Your Room

Often people are in search of quite place without any disturbance, and many times fail to search such place. Here the researchers at Swiss have successfully invented a curtain made up of sound absorbing material. This curtains can be used in offices, restaurants, conference halls, hospitals.etc.

In old days curtains made up of velvet, heavy glass partition  were used to keep outside noise out. Recently Empa researchers  with the special assistance of famous award winning interior designer Annette Douglas and silk weavers Weisbrod- Zurrer AG has developed this new type of curtains.

These curtains are made up of translucent, lightweight material capable of absorbing sound five times more than that of any fabric. The head of Empa’s Acoustics/ Noise Control Division admitted that “Acousticians are pretty astonished when they see the readings we are achieving with the new curtains in the reverberation room. The weighted sound absorption coefficient is between 0.5 and 0.6. In other words, the new textiles 'quench' five times more sound than conventional translucent curtains. The new curtain genuinely absorbs sound, noticeably improving the room acoustics – and its design is also very high quality."

In other words these curtains are more conventional than translucent curtains. Its maximum effect can be obtained by keeping the gap between the curtain and the wall just 15cm. The moment this fabric was launched it has become more popular. These curtains have become more in-demand as they are the best at noise absorption. Its first virtual model was developed on computer just to see its efficiency. After many microscopic fabric tests done on that model finally Weisbrod-Zürrer suggested it as sophisticated material and displayed its characteristics.

"We developed a computer model which simulates the micro- and the macroscopic, acoustical and mechanical behavior of traffic" said Reto Pieren, a researcher at Empa, the Swiss Federal Laboratories for Materials Testing and Research, who helped develop the curtains.

Some related points to this curtains are:

• The curtains are well able to absorb high frequency than the low frequency noise because of their low wavelengths.
• They cannot absorb sound beyond any specific limit as the material is not enough thick.
• These are also named as ‘quite curtains’ as they reduces the noise upto 20dB and are primarily designed for hospitals and hotels.
• The main benefit in using these curtains is that it reduces echo, reverberations and interference from outside noise.
• They can best be used in industries where sound-proof sections are needed.

Thus the sound proof curtains are best substitutes in place of regular fabric curtains and heavy glasses.
