Sonphonon Self Adhesive Acoustic Dampers
Simply stick it to the impact zone/vibrating surface. The damper will form a constrained layer and convert the vibrational energy into negligible amounts of heat which will reduce noise and vibration. These dampers are used in railway carriages, automotive, hi-fi, hoppers, chutes, weighers, vibratory feeders… in fact they are worth trying anywhere that steel/aluminium is resonating and transmitting noise. The material is fire certified to BS 476 parts 6&7.
Self Adhesive Dampers range from 0.5mm to 6mm thick they can also be cut or lasered to size. Click for video link
Phonon (fonon) ( KEY ) , quantum of vibrational energy. The atoms of any crystal are in a state of vibration, their average kinetic energy being measured by the absolute temperature of the crystal. In certain phenomena it becomes evident that this energy is divided into discrete bundles (see quantum theory ); the energy bundles behave like particles in some respects and are termed phonons. These effects are most apparent at low temperatures where only a few phonons are present. For example, interactions between phonons and electrons are thought to be responsible for such phenomena as superconductivity .
Sound Dead Foam
This is available in 2000mm x 1000mm sheets in a range of thicknesses from 12mm to 100mm, open cell or sealed face for oil mist/damp environments. It can also be supplied cut to size. It can also be supplied cut to size.
I need the section below regarding how to work with SDS, grades available & polymer types, but it is probably too long for the products page.
