Today I want to demonstrate this common misrepresentation and help you be aware of some things you need to verify when comparing machines. On a pivotal style vibration machine, frequencies above 18 hertz are critical to achieve some of the known researched and advertised benefits associated with whole body vibration. They key to unlocking certain benefits is ensuring a machine has an adequate frequency range.
If you were to get into your car and your speedometer displayed a range of 0-200 speeds you’d be asking yourself is it miles per hour? Is it kms per hour? If a vibration plate has a display in speeds or levels – it is not defined – you don’t know what you are actually getting as a frequency unless the manufacturer has clearly stated in their specs.ĭifferent frequencies drive a range of different benefits. In the world of vibration machines, the language of “speed” is measured in Hertz or the movements per seconds the platform is moving you up and down.
Today we are looking at frequency in more detail in reference to using a pivotal style platform. We have discussed the importance of the relationship between frequency and amplitude in our earlier article 3 Key Terms to Understand About Vibration Machines. Students can document the patterns produced by taking photos, and then draw conclusions about the way sound travels based on their investigation.There are a few critical pieces on information you need to know when considering vibration machines. Have students experiment with Chladni plates and Eidophones that they construct.Create a model eardrum and illustrate sound waves using the ear buds students have on them right now.

Why do you need to use a frequency generator to produce these patterns? Why can’t you just playing a song?.What do these areas tell you about the movement of sound? There are areas in the images that don’t show light.How do Brown and Louviere’s experiments demonstrate that sound travels through liquid?.What creates the patterns in the water or sand on a Chladni plate?.

The resulting work became Resonantia (Latin for “echo”), a multimedia project centered around 12 images produced by vibrations.Īccess the full article here. By spreading fine sand across the top of a metal plate and running a violin bow alongside, Chladni showed that the sand would settle into distinct patterns, depending on the frequencies of the sound waves produced by the bow.Ĭenturies later, in the 1960s, a Swiss physician named Hans Jenny built on Chladni’s experiments in an effort to study vibrational phenomena - what he called “ cymatics.” Visual artist Jeff Louviere happened upon the works of Jenny and Chladni while researching another project, and he and his partner, photographer Vanessa Brown, became inspired to conduct their own experiments to see what sound could look like. In the late 18th century, German physicist and musician Ernst Chladni demonstrated how vibrations could be used to create striking imagery. Used with permission creators: Louviere + Vanessa
