Vibrating Window Negates Noise
Darmstadt, Germany - Engineers are developing glass that vibrates to cancel out sound.
But help is on the way for the restless and sleepless. A noise-negating method that thwarts vibration with vibration could be available for use in apartments, hotels and offices in five years.
"A window acts like a loudspeaker and a membrane. If you control the vibration of the window, you can control transmitted noise in such a way that it is not acting like a membrane or a loudspeaker," said Thilo Bein, head of the business unit for energy, environment and health at Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt, Germany.
