Vibrating Windows to Stop Outside Sounds

Advertising

I live in a crowder area, and I hear cars, people, all day long. Somethimes all this noise can be quite disturbing, but a team of researchers at the Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt, Germany, have developed a vibrating window that negates noise generated by sources as loud and shrieking as jet planes.

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 the institute.

Traditionally, to obstruct intrusion of noise through windows, engineers thicken the glass to double or even triple panes. But there is disadvantage to it; the process drives up the cost of construction.

Now, Bein and his team have developed a method that thwarts vibration with vibration, effectively negating the interference of outside noise through glass windows. The trick, they say, is to stop the sound waves in their tracks. – Source – Discovery

    I play an amplified classical guitar and bass guitar that frequently make my windows rattle and buzz. When I lived in my parent’s house I cracked by bedroom window when I cranked up my Peavey amp when I was playing bass guitar. Now my “new” place has like old windows that buzz real bad when the bass is up and that sucks. It sucks too because stupid people complain about my guitar playing. I can’t afford new windows that are thicker made glass than that old shit used on crappy older houses. One things for sure: nobody’s gonna make me stop playing my guitars!

    I don’t even need an amp to make my windows buzz when I’m playing my upright bass. I’ve got those “weed whacker” super think strings on my bass and even the art work on my wall buzzes when I play. It’s a great way to scare the rats that occasionally get in my walls! It’s almost arousing to a point when you’re causing vibrations strong enough to make windows and walls buzz by playing a bass instrument.
