The dramatic reductions in noise and vibration in sheet metal panels made from Quiet Steel® are due to the very high levels of damping inherent in the material. The effect of damping is to reduce the vibration amplitude of a system which is being excited at, or near its resonant frequency.

Since it is the vibration of a panel that generates radiated noise, the reduction in vibration amplitude due to damping directly leads to reduced noise radiated from the panel. But hearing is believing. Click the Quiet Steel® logo below to hear the difference between Quiet Steel® and standard steel.

A typical sheet metal panel has many resonances and the resulting vibration response has many “peaks” at these resonances. The effect of Quiet Steel on a typical steel panel is dramatic as can be seen below:
