Ignorance and stupidity are not the same. Ignorance is a lack of information whereas stupidity is the inability to comprehend the information available. In my case, however, both apply.

I’m about to discover just how dumb I am on the subject of suppressors because I’m here at Long Mountain Outfitters in Nevada to take a suppressor class from the acknowledged dean of silence, Dr. Phil Dater.

He is one of the owners of a leading suppressor manufacturer, Gemtech, and also consults through his Antares Technologies side-business. Phil, as he prefers to be called, is about to educate me with a graduate-level understanding of cans.
Phil starts with the basics of high school physics, which most of us have forgotten. Sound is a form of over-pressure, a traveling wave that passes through a medium; liquid, solid or gas. If the pressure wave is composed of frequencies that are sufficiently strong and fall within the range of vibrations that affect the human ear, we hear the sound.
What, then, is the sound of a gunshot? I now know it’s a wave of over-pressure, meaning a pressure wave that’s greater than the local pressure of the medium—air. Okay, but how is that sound generated? The answer to this question, it turns out, cuts to the chase of suppressors.
