Why SDS chose the brand name Sonphonon™

Son is short for Sonic which relates to acoustic energy, a Phonon is a measure of vibrational energy. Since Sound Dead Steel controls both it was an ideal choice for the brand name and trademark.

Sonic-, a prefix/infix/suffix for words with meanings that relate to acoustics. Sonic boom, an audible component of a shock wave in air Supersonic and hypersonic speeds

Phonon (f´nn), 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.
