Useful Information – Power Configurations

Before I start applying all of our new knowledge about sound to a discussion of ultrasonics, I thought I would interject this little tidbit of useful information about power configurations. Despite the fact that most companies employ skilled electricians, many of the people involved in specifying and designing cleaning (and other) equipment that uses electrical …

Ultrasonics – Sound – Harmonics

Previous blogs have introduced the phenomenon of resonance.  In fact, most objects can resonate at more than one frequency and in multiple modes of vibration.  This blog will concentrate on resonance at multiples of the the fundamental frequency.  These are “harmonics” of the fundamental frequency. A good model to demonstrate the principle of resonance at multiples …

Ultrasonics – Sound – The Power of Resonance

Resonance, as discussed in a previous blog, can be either or both beneficial and/or detremental.  This blog will explore the beneficial qualities of resonance. Consider the model of a child’s swing discussed in the preceding blog.  We all know that by “pushing” or “pumping” at the right time can easily make the swing go higher and …

Ultrasonics – Sound – What is Resonance?

Nearly everyone has heard the term “resonance” or “natural frequency” but everybody has a little different idea of what resonance is all about.  In fact, this is understandable because resonance means different things under different situations and there are many different ways to produce resonance. Resonance is the condition that arises when, at a specific frequency …
