THIS ONE HURTS: 432HZ VS 440HZ
What is a Hertz?
Hertz (Hz) is a unit of measure that equals the number of cycles per second, which is frequently used in electromagnetic waves, electrical currents, and our topic today; sound.
Instruments need to be tuned to ensure they are playing in the correct pitch. There's nothing worse than sitting in an orchestra and hearing that single cello playing out of tune.
The History
Before standardization, many countries
followed the standard of 435Hz, which also happened to be the Austrian government's recommendation. In 1859, the French government passed a law standardizing tuning to 435Hz. However, in 1834, Johann Heinrich Scheibler invented the "tonometer", a device with 56 tuning forks, and recommended the use of 440Hz. In 1926, the American music industry also reached the informal standard of 440Hz; some manufacturers even began producing instruments in the frequency.
The world came to an agreement in 1953, the middle "A" on the the piano would be tuned to 440Hz. To this day, the argument between the frequencies continues.
The Fight for 432Hz
Many people believe that 432Hz is more in tune with the universe, offering physical and mental advantages. In Paul Davids' YouTube video, he offers a great explanation, "There is belief among some that 432 is more in harmony with the universe." When playing in 432 tuning, middle C is closer to 256Hz, a frequency that is a multiple of 8Hz, a rate that is known as “the heartbeat of Earth.” 432Hz also resonates with the golden ratio.
While many people talk about the positive effects 432Hz has on the body, and the possible negative effects 440Hz has (check out this conspiracy podcast about 440Hz), studies haven't been able to show anything other than a personal preference. A study have been able to find minimal differences in the frequencies and bodily rates, such as a slight decrease in blood pressure values, a slight decrease in respiratory rates, and a decrease in mean heart rate. The key word here is "slight", and unfortunately for the 432Hz team, isn't enough proof for their cause. In order for something to be regarded as "healthy" and overall better for you, extensive research needs to be done. There are a lot of variables for a study of this sort, making it nearly impossible. Think of all of the instruments that need to be studied, controlled, and tested, along with every possible health outcome.
I'm sure we'll have this few centuries old question answered at some point in the future, but what frequency do you prefer? Or can you even tell a difference? Take a listen to Davids' video and his frequency comparisons and let us know below, and be sure to check out the rest of his channel.
