Noise cancelling technology for windows
Share
For once, vibrations are causing less noise. Thilo Bein, head of the business unit for energy, environment and health at Fraunhofer Institute for Structural Durability and System Reliability LBF, has a German team working with treating glass with small squares of piezo-electric material. When the glass vibrates from a soundwave, the material counter-vibrates to cancel out the sound entirely, meaning you get to sleep right through that jet blast or jackhammer. [GT]
