Particle Damping Technology
Numerical and experimental results indicate that the best effect can be achieved when using a structure of several chambers for particles.
Particle Damping Technology is one of the most effective in passive vibration dampening, due to the ability of the particles to operate over a wide frequency range and withstand a long service life
