Same thing happens with playing stringed instruments. When an open string's note is played on another string, the open string will hum and vibrate, resonating with the frequency
@@Mantium47you can do, but its often very subtle, the sympathetic resonance is often small in amplitude compared to the primary. So the strings will not be vibrating with as much energy. It varies so much from one instrument to another, fixed or floating bridges and trems (whammy bar), potentially even construction materials. Its also somewhat common to intentionally mute certain strings to prevent the vibrations creating sounds, like when tuning. Although some people like to tune around or work with them. But don't quote me, I am a terrible guitarist at best and a largely self taught physics fan!

It's called sympathetic resonance. A lot of classical Indian music relies on unplucked strings that are only activated by sympathetic resonance, which is part of what gives it a droning sound.
@@mudit1 when you watch classical Indian string players, watch for the strings on their instrument they never touch. These are the sympathetic strings that drone behind the music.
I use this property to tune my guitar. there's actually a physical technique stringed musicians use called harmonics where we separate the string at very specific spots to make one string resonate 2 notes.
I’ve been playing guitar for 94 years and am a certified master luthier. Everything you just said is complete bullshit. If I ever find you, I will smash your guitar to splinters with my hammer that I hand forged from bronze to show you what a real harmonic sounds like.
This is why the hydraulic pumps on fighter aircraft rotate at slightly different RPMs. If they spun at the same RPM, they would harmonically synchronize and destroy themselves.
I knew about sympathetic frequencies and feedback, but this is incredible. This might help explain why people experience music/vibes and so on, as they do.
I play a semi hollow electric guitar that when played along a bass, certain frequencies make the guitar “breath” through the sound holes of it. When the bass hits certain notes, the sound waves travels through my guitar and the vibrations been felt as air from the sound holes. It’s a really cool experiment.
It also works in octaves. Becomes annoying when playing classical guitar because some strings will resonate when you don’t play them. Sometimes you have to mute them. Also if you play a loud chord on electric guitar or speakers, another guitars strings will begin to vibrate
As a guitar player I use this when tuning my instrument. If I'm tuning to an open D, some of my strings I've already tuned will start to resonate when I correctly tune my other strings! Edit: to anyone who thinks this isn't a good idea, I'm sorry you don't have as good of ears as me. Because when I go back and check, low and behold, they're spot on 95% of the time. Crazy the amount of doubt the Internet has
Great example. I think this is a good way to show how resonant inductive wireless power transfer works. Amazing how seeing the effect makes such an impact.
I believe in music we call this phenomenon: sympathetic frequencies. For example, one struck string in a piano will cause some of the other strings to vibrate depending on their individual frequency setting or tuning.
close. sympathetic resonance. When I tune my guitar, I get more accurate results if I mute the other five strings, because each one will sympathetically vibrate slightly when another one is ringing, reducing the tuner's accuracy.
I should've added: Sympathetic resonance will produce sympathetic frequencies. You were closer than my first comment would suggest (sorry about that) :,)
I used to play a upright piano with panels open in the same room that stored a drum set. Always loved being able to get the kick and the snare to rattle just by playing the piano.
This is how the first tv remotes worked. The remote had a piece of metal that the button would hit and it would make a high pitched tone. And inside the tv was another piece tuned to the same frequency and it would activate a switch.
@@dat2ra hahahha omg I completely forgot this memory - we had one of these too. But I was too young back then to understand why the programm changed lol
@@stuartdparnellAcoustics arent the reason that a wireless transformer works; it's actually a magnetic field generated by an inductor when a voltage is applied to it. Another inductor will produce a voltage at the same frequency, but the waves of magnetic field and flux aren't like sound waves
@@axidhaus humans have been using vibration and frequency for thousands of years but we really had that shit down pre egypt(pre cataclysm, probably, end of younger drias around 12,000 years ago) at least that makes the most sense to me, seeing what i’ve seen
Early tv remotes worked off this principal. Pressing the button on the remote struck a piece of metal inside it that produced a specific pitch. The tv had a tuning fork in it that reacted to that pitch and would change the channel you were watching. Back then, there were only 3 tv channels, so remotes only had one button. Power and volume controls came later, when they switched to RF and IR remotes.
@mmMilitza it was before my time, but people used to call tv remotes a clicker. Another factiod about those types of remotes was any sound that would make that tuning fork vibrate would change the channel. If someone dropped their keys close to a tv, the channel would change.
We had one of the first B/W 1957 “ZENITH” TV’s with that type of remote “clicker”. The cabinet of the TV was a pale beige bleached oak. When you clicked on the channel change button, you could hear a motor whiz/whirl inside the set. It didn’t have any batteries either.
@mmMilitza BTW- If someone stood between the “remote” clicker and the TV, NOTHING would happen, move and you’d get your channel change, volume ⬆️or⬇️, On or Off. Just don’t lose that remote!
This is exactly how dolphins or whales communicate with each others. They use a specific noise with high frequency that only they themselves can hear, and based on the length of those noises, they can convey exactly what they want to express to others of their kind.
@@cgrisby1965 "This is how dolphins and whales communicate with each others." Where in the video is the sound we can't hear? average 🤡 reading comprehension
I found this out when I was a kid. My guitar was in the corner of my room and one day I decided to start singing, which I do normally, but this time I hit a note that perfectly matched the tune of one of my guitar strings and it started vibrating as I was singing.
It can happen with string instruments too. For example, if you play an A note on a different string on a violin and the frequency is just right, it can also make the A string start vibrating as well.
This is an important concept for bass players, where the low frequencies carry so much energy that playing without muting every other string makes the sound incredibly muddy, since the other strings start vibrating. I have no actual mathematical basis for this, but I'd guess that if high energy enough, one note can make a string of another note vibrate, as long as the note is a harmonic of the string.
Each frequency is like another dimension. That’s why we can have radio signals so close in frequency and they don’t interfere with each other. You CAN get passive intermodulation “PIM” from another wavelength when it’s a dirty signal. That’s when you’re pumping a lot of power to your signal though.
Crazy.. by a lot of power do you mean like Volts Amps Watts or dose dB mean power of signal? Which may need more Watts to produce? Just curious as I've seen 2 way aerials advertised with dB rating.
@@alexhaze9709 where to start 🤔 We use radio waves to send signals all around us right, like cell phones, television, radio stations etc. Each radio station is a different radio wave/frequency for example. There are a bunch of different radio stations flying around in the air without interfering with each other. The reason for this is because each frequency is a different height. When a tone is started at a particular frequency, with an antenna and a transmitter (a cellular radio uses about 1520w for example), it will remain that same frequency as it travels. Echoes of it will ripple off into third and fifth harmonics that may effect other frequencies that fall into those harmonics/frequencies.
A musician myself of stringed instruments for 35+yrs. This anomaly can cause strings to vibrate and sounds that mix and cause a lot of noise. Nightmare when recording with several instruments
Really? I'm abhorred at this. Obviously it doesn't only work when they match frequency. It clearly has to do much with the harmonic series and overtone decompositions / prime decompositions and the fourier. It's the same reason a snare drum vibrates at different various amplitudes over the entire frequency space! Not only on, say, 260Hz specifically. That is absolute nonsense! Can't believe I don't see more people in the comments pointing this out, and this guy is repping NASA and doesn't understand proper nuance. THIS WILL WORK AT 130HZ, even small rationals times 260 to various amplitudes, for crying out loud!!!
@@uncopino You do need one of the frequencies to be an exact match, just not necessarily the fundamental. That's how the A and D strings can vibrate together, since the relationship between them is f(A) = 3/4*f(D). There is a harmonic that they share in common.
This is why on the Violin, if you play an open G string, you can press your finger on the G note on the D string which will create an over tonal effect
That's cool! I've never tried that on the cello. I've done it the other way around... Finger a D on the G string or a G on the C string or even an A on the D string and the open string will continue after you silence the fingered string.
The resonance excites the "line" fast enough to 'out of tune - higher' Because, "line" held to same frequency vibrates "line" faster than that frequency
Sympathetic resonance. Many musicians are familiar with this dynamic. If you sing into the sound hole a guitar at the pitch of one of the open strings, that string will vibrate.
We studied wave interference, destructive and resonating, in my HS physics class. Fascinating stuff. The coolest illustration I heard was when we set up 2 parallel speakers pointed straight ahead and then walked through the wave field and heard the sound level go up and down as we crossed through the wave pattern. In some places, it was almost silent, even though both speakers were quite loud and close. (Only woks if the speakers are playing a single tone of the same frequency.)
Tonal blind spots are with 3d geometrical positioning that specifically pertain to recording room studio constructioning of dampening/reflecting/absorbing... To change the positions in the room to attenuate sound around recording pickup For first compression - it starts with optimal sound gather, then the cleanup of total gain is applied
My seventh grade English teacher has a tuning fork that she would hit when we got too loud and we had to raise our hand when we couldn’t hear it any more. Everyone would shut up real quick cause they wanted to be the last to hear it

130 yes. 520 maybe. In tech school we were taught that there's no such thing as a subharmonic because by definition a harmonic is a multiple of the fundamental frequency. That's in electronics. Mechanical systems might not work that way.
Interesting how the note the ball makes when hitting the tuning fork is an octave and a 5th above it. One of the harmonics, not the fundamental

Same thing happens with playing stringed instruments. When an open string's note is played on another string, the open string will hum and vibrate, resonating with the frequency
Can you generate enough sound to create cool sounds with resonance/note combos?
@@Mantium47you can do, but its often very subtle, the sympathetic resonance is often small in amplitude compared to the primary. So the strings will not be vibrating with as much energy.
It varies so much from one instrument to another, fixed or floating bridges and trems (whammy bar), potentially even construction materials.
Its also somewhat common to intentionally mute certain strings to prevent the vibrations creating sounds, like when tuning. Although some people like to tune around or work with them.
But don't quote me, I am a terrible guitarist at best and a largely self taught physics fan!

I play a semi hollow electric guitar that when played along a bass, certain frequencies make the guitar “breath” through the sound holes of it. When the bass hits certain notes, the sound waves travels through my guitar and the vibrations been felt as air from the sound holes. It’s a really cool experiment.

@@barrilitomusic tune it to Eb standard and watch it open up
It also works in octaves. Becomes annoying when playing classical guitar because some strings will resonate when you don’t play them. Sometimes you have to mute them. Also if you play a loud chord on electric guitar or speakers, another guitars strings will begin to vibrate
My guitar teacher taught me the concept of resonation by singing into his acoustic guitar
ok man
Yeah. I've cranked up a guitar amp afterhours at my shop and all the acoustic instruments started ringing. Lol

@@Untoldanimations could be hardware/metal parts of the bridge vibrating into a string.
Great example. I think this is a good way to show how resonant inductive wireless power transfer works. Amazing how seeing the effect makes such an impact.
I believe in music we call this phenomenon: sympathetic frequencies. For example, one struck string in a piano will cause some of the other strings to vibrate depending on their individual frequency setting or tuning.
close. sympathetic resonance.
When I tune my guitar, I get more accurate results if I mute the other five strings, because each one will sympathetically vibrate slightly when another one is ringing, reducing the tuner's accuracy.
I should've added:
Sympathetic resonance will produce sympathetic frequencies.

@@zedmelon thanks for the tip

This is how the first tv remotes worked. The remote had a piece of metal that the button would hit and it would make a high pitched tone. And inside the tv was another piece tuned to the same frequency and it would activate a switch.

@@axidhaus humans have been using vibration and frequency for thousands of years but we really had that shit down pre egypt(pre cataclysm, probably, end of younger drias around 12,000 years ago) at least that makes the most sense to me, seeing what i’ve seen
Early tv remotes worked off this principal. Pressing the button on the remote struck a piece of metal inside it that produced a specific pitch. The tv had a tuning fork in it that reacted to that pitch and would change the channel you were watching. Back then, there were only 3 tv channels, so remotes only had one button. Power and volume controls came later, when they switched to RF and IR remotes.
@mmMilitza it was before my time, but people used to call tv remotes a clicker. Another factiod about those types of remotes was any sound that would make that tuning fork vibrate would change the channel. If someone dropped their keys close to a tv, the channel would change.
@mmMilitzaMy nana is 90 and goes on TH-cam and facebook all the time lol
We had one of the first B/W 1957 “ZENITH” TV’s with that type of remote “clicker”. The cabinet of the TV was a pale beige bleached oak. When you clicked on the channel change button, you could hear a motor whiz/whirl inside the set. It didn’t have any batteries either.
@mmMilitza
BTW- If someone stood between the “remote” clicker and the TV, NOTHING would happen, move and you’d get your channel change, volume ⬆️or⬇️, On or Off.

I found this out when I was a kid. My guitar was in the corner of my room and one day I decided to start singing, which I do normally, but this time I hit a note that perfectly matched the tune of one of my guitar strings and it started vibrating as I was singing.
It happens sometimes when I sing next to my guitar, sometimes I hear its strings vibrating after I sing a specific note
If you strum a guitar, every guitar in the world strums along with you…
😂😂😂 I needed that
If you play the right notes on a guitar, your drummer needs to start playing or throw the snare lever cause it just wont stop buzzing 😂
I like that. :)
It can happen with string instruments too. For example, if you play an A note on a different string on a violin and the frequency is just right, it can also make the A string start vibrating as well.
This is an important concept for bass players, where the low frequencies carry so much energy that playing without muting every other string makes the sound incredibly muddy, since the other strings start vibrating.
I have no actual mathematical basis for this, but I'd guess that if high energy enough, one note can make a string of another note vibrate, as long as the note is a harmonic of the string.
Because they generate frequencies to do so 😂
thats how ppl can break glass with their voice, matching the frequency of that the glass makes
Each frequency is like another dimension.
That’s why we can have radio signals so close in frequency and they don’t interfere with each other.
You CAN get passive intermodulation “PIM” from another wavelength when it’s a dirty signal.
That’s when you’re pumping a lot of power to your signal though.
Crazy.. by a lot of power do you mean like Volts Amps Watts or dose dB mean power of signal? Which may need more Watts to produce? Just curious as I've seen 2 way aerials advertised with dB rating.
@@alexhaze9709 where to start 🤔
We use radio waves to send signals all around us right, like cell phones, television, radio stations etc.
Each radio station is a different radio wave/frequency for example. There are a bunch of different radio stations flying around in the air without interfering with each other.
The reason for this is because each frequency is a different height. When a tone is started at a particular frequency, with an antenna and a transmitter (a cellular radio uses about 1520w for example), it will remain that same frequency as it travels.
Echoes of it will ripple off into third and fifth harmonics that may effect other frequencies that fall into those harmonics/frequencies.

Really? I'm abhorred at this. Obviously it doesn't only work when they match frequency. It clearly has to do much with the harmonic series and overtone decompositions / prime decompositions and the fourier. It's the same reason a snare drum vibrates at different various amplitudes over the entire frequency space! Not only on, say, 260Hz specifically. That is absolute nonsense! Can't believe I don't see more people in the comments pointing this out, and this guy is repping NASA and doesn't understand proper nuance. THIS WILL WORK AT 130HZ, even small rationals times 260 to various amplitudes, for crying out loud!!!
I remember how shocked I was when I did this on my violin. If you play an "A" on the D string, the A string resonates as well.
If I cough the strings on my western guitar six feet away will respond and hum along 😂
exactly. the frequency doesn’t need to exactly match
@@uncopino You do need one of the frequencies to be an exact match, just not necessarily the fundamental. That's how the A and D strings can vibrate together, since the relationship between them is f(A) = 3/4*f(D). There is a harmonic that they share in common.
Wow😲Physics cs is really nice I love it💗
This is why on the Violin, if you play an open G string, you can press your finger on the G note on the D string which will create an over tonal effect
That's cool! I've never tried that on the cello. I've done it the other way around... Finger a D on the G string or a G on the C string or even an A on the D string and the open string will continue after you silence the fingered string.
The resonance excites the "line" fast enough to
'out of tune - higher'
Because, "line" held to same frequency vibrates "line" faster than that frequency
Also can be used for dual-toning chord root for greater usable range of alternative chording😊
It's so exciting when you find someone on your same frequency!
Off subject
