"Quelching" noise as well as light and translucent, a combination that has been lacking in the market until now
Acoustic tests with the new sound-absorbing curtain in a normal living room: measuring the reverberation time with a loudspeaker and microphone
Sound absorption measurements in Empa's reverberation room, show that depending on the frequency, the new curtain absorbs up to five times more sound than typical lightweight curtains
Heavy curtains made from thick material such as velvet are often needed to keep noise out of indoor environments, but Swiss researchers have come up with another option. The Empa researchers, in collaboration with textile designer Annette Douglas and silk weavers Weisbrod-Zurrer AG, have developed lightweight, translucent curtains which are five times more effective at absorbing sound than their conventional counterparts.
