📄𝗧𝗿𝗮𝗻𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:American singer Tim Storms holds the Guinness World Record for the lowest voice of anyone on Earth. On March 30, 2012, he produced a sound that was slightly more than seven octaves below the lowest note on a piano. The sound was so low - just 0.189 hertz - that his vocal cords, twice as long as those of an average adult male, would have been vibrating just once every five seconds. That’s well into the infrasound range, below about 20 hertz, that’s undetectable to human hearing.
Although most musical instruments aren’t designed to play outside our normal auditory range - for obvious reasons! - some can produce infrasonic notes. One of these is the octobass, a gigantic version of the double bass.
The lowest open string on the Montreal instrument sounds the note A0, with a frequency of 27.5 hertz, but an octobass at the Musical Instrument Museum in Phoenix, Arizona, fitted with modern wire-wound strings, is tuned to produce a lowest note of C0 (16.4 hertz), in the infrasound range.
Large pipe organs can go down to C-1, or 8 hertz, which may seem pointless. However, just because we can’t hear something that low doesn’t mean we can’t be affected by it. In 2002, a live experiment called “Soundless Music” was carried out to explore the psychological effects of infrasound.
Under the guise of a concert featuring a variety of electronic and deep bass sounds, an infrasound generator was incorporated into the mix. Afterwards, the audience members were asked to describe what they experienced. Many people reported feelings of anxiety and foreboding, along with cold and tingling sensations.
French scientist Vladimir Gavreau became a pioneer of infrasonic research following his unexpected encounter with ultra-low sounds in 1957. He and his team of acoustical engineers were working in a large concrete building when the group began experiencing bouts of nausea, which at first were assumed to be due to chemical fumes or some pathogen in the air. Weeks of investigation revealed the true source of the problem: a loosely mounted low-speed motor.
The team built special equipment to detect the vibrations from the motor and eventually tracked the cause of the nausea down to 7-cycle-per-second infrasound waves. These waves from the motor induced a resonance in the ductwork and structure of the building, which amplified the original sound and led to its unpleasant physiological effects.
The discovery triggered a wave of research into building acoustics in the ultra-low-frequency regime. Today, it’s routine in new architectural schemes to test for and eliminate any infrasonic resonances and use sound-proofing where needed along with materials with special sonic properties.

There are lots of machines that are intentionally made to emit infrasound, and they are used in public spaces and buildings to make people anxious.

infrasound undetectable... but I heard it.

[@dwalto02]

At the beginning the narrator said "Once every five seconds", which is not correct. What they meant to say is 5 times per second which is 20 hz.

[@kaedeschulz5422]

5times a sec is 5hz

[@dwalto02]

@@kaedeschulz5422. Correct five times per second not a cycle every five seconds like they said.

@@dwalto02 one vibration every 5 seconds => 1/5s = 0.2Hz ~ 0.189Hz As they claim, it was the recorded sound of American singer Tim Storms which is purportedly WGR.
Hence, they didnt't make any mistake by stating "Once every five seconds". It's an approximation. Storms must have done less than once per 5sec actually...

@@profesormacimaka4372 Thank you for the reply. I wanted to say, that what they showed on the video was not him getting anywhere near .189Hz, so they showed an incorrect clip. Secondly, I completely refute that someone moving their vocal cord once every 5 seconds would be possible. In order for it to be a vibrating vocal cord, it would need to by vibrating back and forth, once every 5 seconds. Vocal cords are so small, short, light, that there is absolutely no way that it gently moved in 1 direction at 2.5 seconds and then the other direction at another 2.5 seconds. Rather... he made once click in one direction of his vocal cord and then 5 seconds later, did it again... possibly in the other direction, if someone was looking in there at his cords. However, that is not a vibrating cord. That is him blowing air across his vocal cords once... continuing to breathe gently and then doing it again 5 seconds later. I refute the record completely actually :)

I didn't know someone could have a deeper voice than Corpse

Omg he must be rich 🤑🤑🤑

Instead of showing irrelevant clips, why don't you visualize infrasound and its effects?
