Hertz – The Frequency Man

Or Hz as he is more commonly known for his great leap in science and our knowledge of the invisible part of the spectrum, the light spectrum, the wave spectrum or the radio wave spectrum, the invisible waves that are US and OUR environment, increasingly.

While the introduction of wireless radio was a huge leap from copper connected phone and telegram, with far-reaching effects for humanity and technology ( including the Spanish flu?), successive leaps launch us into a soup of so many frequencies only dreamed of.

Heinrich Hertz, like Nikolai Tesla Maxwell and Edison were feeling the vibe and tapping into the opportunities of discovery from the electric field, from the aether.

Of interest and note, Hertz theorized and proved the Photo-electric cell which Albert Einstein subsequently won a Noble Prize for his re-iteration of it in a version that deleted the aether and took science and technology on a quantum physics journey of photons and atoms.

Therefore the Frequency man was very well in tune with the aether but not as attuned to Einstein and the path technology and wave propagation via apparatus and receiving devices, leading us here to 2020 and the clash of these titanic theorems, the consequences of and the opportunity to learn now what it all means, what the Frequency Man said and where its all led as we now spiral to dizzying heights of accelerating frequency, all of them impacting our bodies and environment for benefit or harm depending on the frequency and our sensitivity to it.

This is a brief introduction to Hertz and his wonderful discovery and his contribution to wave science. We will add more Hertz links from readers information and links as well.

The man behind the measurement

Anyone who reads the technical data for loudspeakers will come across values given in hertz (Hz) and kilohertz (kHz).  This is how manufacturers indicate a loudspeaker’s frequency range. The ideal system would have a 20/20 range  – 20Hz and up to 20 kHz which corresponds to what a young, healthy adult can hear (sadly, our ability to hear the upper frequencies diminishes with age).

Pretty neat that we can nail down numbers like this and then make purchases based on clearly defined specs, and there’s one man who deserves the credit for making this a reality: Heinrich Hertz. Before his hard work and ingenuity, Hertz was merely a last name and no one had the slightest idea as to the scientific underpinnings responsible for differences in pitch.

Heinrich Hertz was born in 1857 to a wealthy family in Hamburg in what was then the German Confederation. In 1880, Hertz received his PhD from the University of Berlin and went on to become a professor of physics in Karlsruhe and Bonn.

Hertz was also involved in research with particular interest in the English scientist James Clerk Maxwell’s theory regarding the interaction between electric and magnetic fields. While static on their own, Maxwell belived they could come together to create something dynamic.

James Clerk Maxwell lays the foundation

In 1865, Maxwell published the paper “A Dynamic Theory of the Electromagnetic Field” positing that when electric and magnetic fields converged they took the form of waves moving through space at the speed of light; and further, that light was, in fact, an expression of electromagnetic waves occurring at a specific wavelength. Maxwell also predicted the existence of radio waves.

Today, exposed to so many benevolent and harmful frequencies, its useful to examine the pre-quantum physics science, in the search of clues, to guide us to a proper understanding of the invisible waves around us and comprising us, and more healthy integration with public and private services, communications, industrial, medical and entertainment.

We owe it to ourselves to know the science and know what science and technology is of benefit and what is of harm to ourselves and our environment.

Hertz opens the door to the practical application of electromagnetic fields

Heinrich Hertz. In 1886, Hertz succeeded in constructing a device that
could prove the existence of electromagnetic waves and was even able to
determine their varying lengths. In later experiments, Hertz managed to
measure the velocity of electromagnetic radiation and discovered it to
be the same as the speed of light, as Maxwell expected. By elucidating
these and other qualities of electromagnetic waves, Hertz opened the
door to research into electromagnetism leading to its practical
application in telegraphs, radios, televisions, and, of course,

In loudspeakers, electromagnetism is used to
generate sound that corresponds to the electric charge fed to the system
as alternating current. This is the audio signal, an electrical image
of the accoustic waveform. When the audio signal is passed through the
voice coil, it both creates an electromagnetic field and causes the
direction of this field to change rapidly. This in turn makes the coil
vibrate with a frequency and intensity determined by the audiosignal.
When amplified by a cone, the vibrations create sound waves.

generated by an electromagnetic field in a loudspeaker, sound does not
consist of electromagnetic waves, traveling, as it does, much slower
than the speed of light and requiring air as a medium to move. Yet like
electromagnetic waves, sound occurs as a series of sine waves, or
oscillations with a waveform that can be defined as a sine curve, and so
the same measure of frequency – the hertz – can be applied.

can therefore be doubly grateful to Heinrich Hertz: He pointed the way
towards the practical applications of electromagnet fields and gave us a
way to measure one of the most important aspects of sound.
