Resonant frequency is the basis of ultrasonic testing, which is used to determine the safety of structures ranging from pipelines to airplanes. Incidentally, real-world tests involving resonant frequencies offer more than an excuse to shatter glass. And if you can find a wine glass with a flaw in its structure, even an invisible one, that helps by providing a weak spot. An empty glass cracks more readily (although less dramatically) than one containing wine air, being less dense than liquid, carries sound better. It's fine and thin – unlike, say, a beer stein – which maximizes the amount of stress per particle. More likely, a boost of electronic amplification would be needed.įinally, the glass must be strategically selected. Even then, he or she would have to be so close as to risk serious facial cuts if the glass explodes. While conversational tones average 50 to 60 decibels, a trained vocalist might have the pipes to approach the approximately 105 decibels needed to break glass. The note also has to be loud too, a quality known as intensity. To shatter glass, the note's frequency must be the same as that of the glass. They're shorter and "choppier" thus more of them pass through per second, at roughly 556 hertz. Glass-shattering waves carry more energy. (The quality of your neighbor's speakers also will affect the quality of the sound.) Thus, the plaster's resonant frequency must fall somewhere in that range, because when a substance encounters a frequency it matches, it absorbs the energy rather than reflecting it. The frequency of a bass guitar's lower, deeper notes run from 40 to 150 hertz. For example, suppose your bass guitar-playing neighbor cracks the plaster on your walls when she plays a low, driving bass line. Frequency refers to the number of waves passing through a given point over a given period of time, and we measure frequency in hertz: one hertz equals one wave per second.Įvery substance has a natural, or resonant, frequency - the frequency at which its own atoms vibrate. Like electricity, sound energy travels through substances in waves, which "excites" the substance's particles and causes them to vibrate at a certain frequency.
