Acoustic Panel: As the tower’s skin, the acoustic panels are provided maximum exposure to city noise. Contextual frequencies vary greatly in this urban environment, encompassing people [pedestrians + building inhabitants], vehicles, trains, and even aircraft. Each 15’ x 30’ panel contains multiple metal bands with individual tuners, allowing the bands to resonate at different frequencies.
Tuning the bands requires sensors to be located throughout the building that constantly perceive present frequencies and inform the tuners how to appropriately adjust. The tuners function as clamps: they slide into position and compress, changing the bands’ effective lengths and therein their resonant frequency (Coalescing the bands with the contextual frequencies maximizes vibration amplitudes, improving the efficiency of sound collection). A magnetic rod wrapped in a copper coil runs the length of the metal strap, creating a magnetic field altered by every movement of the metal bands: a process called electrostriction. A piezoelectric transducer transforms the magnetic movements into an electrical current that is stored in a unit at the end of each band and then transferred to a building storage compartment that regulates the tower’s electrical needs.
