noise power


The design transfers high decibel (dB) noise produced by elevated railroad into electricity through the vibration of input speaker and drive the vibration of coil, which result in electricity. In the meantime give rise to reflected wave for noise reduction. Moreover, light effect outside the sound insolation walls will be shown which is triggered by the sonic wave when the train pass by, using energy storage of the kinetic energy generated by floor vibration and solar energy. The design lets the traditional sound insulation facilities transfer into new constructions that embellish the city. In addition to sound absorption and noise reduction, it create a higher quality and more harmonious environment for the residents who suffer from the noise pollution.
