How Perforated Metal Panels Deliver Predicable Acoustic Performance

Zrozumiałe, że perforate metal pracuje jako well for akustics wymaga brief look at t sound behavor. When sound waves meetter a solid, sealed barrier, they reflect back into the space, contribung to echo and reverberation. When they meether a precisely perforate panel, thee sound energy passes distrigh thee he he he le s and enter a controlled air cavity behind the panel.

Thee Helmholtz Resonator Principle

Each hole in a perforate metal acts as s narrow neck of a Helmholtz rezonator. The air cavity behind the panel functions as the spring. As sound waves enter the narrow perforation, thee air mass oscillates, and friction against thee walls of the hole converts the acoustic energy into minute hole, thy worchicates effectively removes specific specific specimences frescies from thee environt.
