DESCRIPTION AND STRUCUTURE
A single AS-P transmits mass rigidity and great inertia to the entire surface of the panel or the wall you wish to treat. With the vibration analysis will be obtained excellent results thanks to a significant attenuation of resonances.
For example with a AS-P as that in the drawing applied on a panel of chipboard veneered real wood with dimensions of 400x300x19 mm. we obtained an attenuation of the resonances over -40 dB. See graph. AS-P can be built in different sizes and shapes than the basic form. Keep in mind that a small variation in the size of the AS-P there will be a large variation in weight. The tube can be of a different material from the aluminum without consequences for example to maintain the non-magnetic properties: brass, bronze, stainless steel, and others. The spheres can be of a different material from the Lead for example: Glass, Sand, Ceramic and other, but in this case the damping effect will be less. The shape of the tube can vary depending on the mechanical and aesthetic requirements. For example you can use pipes with rectangular cross section, octagonal, square, triangular, and with forms of ring to put them for example as collars to the transducers.
