Researchers at the www.artstlouis.org Fraunhofer Institute for Machine Tools and cialis brand Forming Technology IWU in Dresden have figured out a way to quiet down the whiney whirring of wind turbines by neutralizing vibrations coming from the central tower of the turbine. They’ve come up with a device that can be mounted to an existing turbine, which senses the vibrations and produces an “anti-sound” vibration, effectively pressing against the sound vibration to cancel it out.
The device could help out with getting more wind turbines into neighborhoods where the chief complaint of noise keeps turbines away. It would be inexpensive compared to http://www.privateeryachts.com/levitra-on-sale other sound dampeners, which are more expensive the viagra no perscription usa better they work, and none of which would work as well as this promising device. While the damper could adjust itself to varying vibration levels, testing is good choice levitra professional underway to see how the device holds up to higher speed winds.
