@Repo-Man Actually it is you that is wrong and the OP is right. Sympathetic resonance actually occurs inside pianos too.

@@AlbertWesker_GOAT Yep, and the frequency of the sounds coming from the truck can even be below the range of human hearing. If a truck is making a 12Hz sine wave, we can't hear that with our ears. But if one of the walls in our house can resonate at that frequency, and we've got a picture hung up on that wall, then the sine wave coming from the truck's engine is going to move that wall, causing the picture to go "tap tap tap" against that wall 12 times a second--a sound we _can_ hear.
@@Siphonife Just as an update, they turned it off at 10pm, on the dot. They're new to the neighborhood. While I still think they don't need their music to be that loud, ever (our yards are all real tiny), and also while I do not consider Sunday night to be deserving of the "hey it's the weekend" benefit, I thought it was very cool that they shut it down at 10. And it was a party, with people. That's even harder to shut down. So they did a great job on that front. Friday or Saturday, I wouldn't even be mad as long as they pack it all up by 11ish (and still, lower volume please). But by Sunday, I really feel like you've got to wrap up by 8. There's a whole neighborhood here. Kids gotta go to school, you know?
You can do this with exact multiples of the same frequency, too. If one is tuned to, let's say, C, then all other C wavelengths will also resonate with it because going up or down an octave is exactly twice or half of the frequency, making the peak of the soundwaves match, and also energising the other fork.
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!
@@Mantium47 thank you brother! I thought you had a very good question and it deserved an answer, even if I may not have been the most qualified person in the room to give you one!
@@Mantium47 There are some of instruments though that have many sympathetic strings (like sitars) that are not plucked but vibrate to create a cool effect!
If you have a guitar in a room, you can "play any string" just using your voice (at the right pitch), and you can still hear the string even after you become quiet.
I got an A+ in my physics class back in 9th grade for doing a test and giving a explanation on this exact same phenomenon. BUT I did it in a guitar store by hitting the E string in the acoustic guitar section and listened as the other close by guitars started resonating as well. Pretty cool
harmonics are mindblowing.(not just talking about the sound version of them... it also happens in various settings like electric systems, mechanical systems, and so on...)
That also works with bridges and stuff, if you reach the resonance frequency of a bridge, for example by troops marching in step over it or the wind, the bridge will start shaking more and more until it collapses. Thats why engineers have to keep this in mind when engineering anything. Same thig with cars, planes, buildings etc.
I think the sound you are talking about is the noise made by the cables that support the mast of a ship colliding with the metal mast. The funny thing is that these cables hit the mast at the frequency of the cable that is blown by the wind. It IS the same as the experiment in the video, very good observation.
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
This is why, in car SPL comps, they’ll play a frequency that matches the inside of the car. Clever. Helps me understand more now you’ve visualised why it works 👍
@@heresjohnny602We live in an existence of frequency. What he said is correct. Pheromones are a real thing as you stated but so is what he said. One does "vibe" with others of higher consciousness. You must understand that we exist in a vibrational/light universe. Scientists measure brain waves of different stages of consciousness. Low frequency brain waves are from that crack head on the sidewalk yelling at passing vehicles. High frequency is the one who is fully enlightened sitting peacefully is absolute mental silence. Energy is very real, understand that fact.
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.
Reminds me as a kid walking into the bathroom while performing vocal warm-ups and discovering that D# was the resonance frequency of the bathroom stalls. The first time it happened sent chills down my spine as the whole bathroom got suddenly louder.
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.
@@Cgraham07I don't know what they mean by vibrations, there's nothing to vibrate in space. These things need a medium for us to receive. It wouldn't be prevalent but a rare phenomenon.
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.
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.

@@Tubemanjac Idk much about old radio communication but I'm guessing they have low range oscillators and some device that does frequency multiplications. Modern electronics use crystal oscillators but idk what they used to use before.
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.

I was once playing the trumpet with my grand dad and you could hear the guitar he had hanging on the wall response to what we were playing, i love physics
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) :,)
This is a very cool demonstration. On piano something similar can happen. If you hold down C in the bass (without making a noise), and play C in another place, the C you played will resonate off the bass C, and you will hear faintly the C you played. This works for any harmonic. For example hold the bass C again, and in the octave above, play C E and G, strong and quick, you will here the C major chord play in the bass C string!
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
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.
What’s also interesting is that the frequency with which the pingpong ball bounces off the first fork is very constant, even though the distance is travels isn’t. I wonder how that happens. Edit: I think I figured out why. Because if the bounce is exactly in sync with the vibration, the fork will have its entire travel time to impart momentum onto the ball and kick it out at max speed. If it reaches the fork out of sync, the fork will already be part way through it’s oscillating movement, and thus impart less force onto the ball. Less force means shorted travel distance means shorter travel time. That way the frequency of the ball bouncing will always be roughly the same because the force with which the ball is kicked off is dictated by the frequency of the fork.
@@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

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
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.
For people who don't know : That's called " spontaneous self organization" where resonant frequency of one object synced with other and they start vibrating at same frequency.
I learnt about this in a limited capacity as a kid learning how to tune drums, if you tune the a drum to the same as another it plays both when you hit one
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!
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.
@@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.
Those moments you're with your best other (friend or significant other) and you get all happy or excited over just living in the moment. You then notice they're just as happy or excited as you... This is the most basic form of that. Find thoes who resonate with you and never loose them or let them go
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
I don't know if it's a physics term or not, but musicians call these sympathetic vibrations. It works to a lesser extent at specific frequency ratios as well. If one fork was pitched to double the frequency of the other, it would work fairly well. If one was 2/3 the other's frequency, it would also work okay. Musically, that's an octave and a perfect 5th, respectively. Piano strings do this a lot. I play Timpani drums. I can test how well they're tuned by singing the note I'm aiming for into the drumhead, and seeing if it vibrates. It's actually a fairly common technique.
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
Something similar to this is commonly used every second almost everywhere: almost any communcation media using radio waves (bluetooth, wifi, radio, tv, you name it!)
This is why people say someone as “good vibes” or they’re on the same wavelength, in case it wasn’t painfully obvious which I have realized as I type out a response to what I’ve now realized is clearly a joke
that is the exact thing you should not do. i mean mixing physics with philosophical statements about life by superimposing words that have completely different meanings in the two fields
Now. The crazy part is that's how all the roadio communication works. The receiver circuit resonates at the transmitted frequency. Thus every station has a different frequency on which the operate.
Estos son los vídeos que aportan, que educan, que sacan de la tiniebla, que alegran poder saber cómo es la física en palabras simples. Miles de gracias
It is exactly how radio works. There's a transmitter at a certain frequency, you can tune in on that and the ball bouncing reflects the audio signal. Electromagnetic waves, not audio waves but the very same principle applies/
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!!!
I used match my whistle to the sound of the alarm beep on the scissor lifts we worked on, you could really tell when you matched it with the resonance , seems to amplify the sound
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

@@thomasbaker9787 do you even know what sound wave frequency is? It has absolutely NOTHING to do with any structures. Anyone who believes that is delusional.
Right now, my neighbors are playing really loud music, and something in my room is resonating with the low end and rattling. So I'm living this exact experiment right now.
Stfu Tom! Let us Rock Out! And your cherry tree is fkn up our backyard.
I just discovered that this is the reason why, when a noisy old truck passes by making low deep sounds, only certain things vibrate and not others.
@@AlbertWesker_GOAT Yep, and the frequency of the sounds coming from the truck can even be below the range of human hearing. If a truck is making a 12Hz sine wave, we can't hear that with our ears. But if one of the walls in our house can resonate at that frequency, and we've got a picture hung up on that wall, then the sine wave coming from the truck's engine is going to move that wall, causing the picture to go "tap tap tap" against that wall 12 times a second--a sound we _can_ hear.
@@tom_something How unfortunate. rofl
@@Siphonife Just as an update, they turned it off at 10pm, on the dot. They're new to the neighborhood. While I still think they don't need their music to be that loud, ever (our yards are all real tiny), and also while I do not consider Sunday night to be deserving of the "hey it's the weekend" benefit, I thought it was very cool that they shut it down at 10. And it was a party, with people. That's even harder to shut down. So they did a great job on that front. Friday or Saturday, I wouldn't even be mad as long as they pack it all up by 11ish (and still, lower volume please). But by Sunday, I really feel like you've got to wrap up by 8. There's a whole neighborhood here. Kids gotta go to school, you know?
You can do this with exact multiples of the same frequency, too. If one is tuned to, let's say, C, then all other C wavelengths will also resonate with it because going up or down an octave is exactly twice or half of the frequency, making the peak of the soundwaves match, and also energising the other fork.
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!
@iliketurtles4463 that's okay it was better than most ahaha
@@Mantium47 thank you brother!
I thought you had a very good question and it deserved an answer, even if I may not have been the most qualified person in the room to give you one!

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

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)
:,)
@@zedmelon thanks for the tip
Good example mate
If a piano weren't an equal-tempered instrument, the sympathetic resonance would be greater.
this resonated to me in a lot of ways :)
🤨
This is a very cool demonstration. On piano something similar can happen. If you hold down C in the bass (without making a noise), and play C in another place, the C you played will resonate off the bass C, and you will hear faintly the C you played. This works for any harmonic. For example hold the bass C again, and in the octave above, play C E and G, strong and quick, you will here the C major chord play in the bass C string!
This is why you don't play guitar in the same room as your other guitars unless they have clamps muting the strings.

@mmMilitzano need to be a dick man
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 😂
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.
@@JesseJames-ig7gu Thanks for taking the time to reply. I learnt something new, I appreciate it.
What’s also interesting is that the frequency with which the pingpong ball bounces off the first fork is very constant, even though the distance is travels isn’t.
I wonder how that happens.
Edit: I think I figured out why. Because if the bounce is exactly in sync with the vibration, the fork will have its entire travel time to impart momentum onto the ball and kick it out at max speed.
If it reaches the fork out of sync, the fork will already be part way through it’s oscillating movement, and thus impart less force onto the ball. Less force means shorted travel distance means shorter travel time. That way the frequency of the ball bouncing will always be roughly the same because the force with which the ball is kicked off is dictated by the frequency of the fork.

physics is so cool when you figure out stuff like this
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 UA-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.

Try with 130, or 520. I bet they'd both have a similar effect on the 260 fork
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.
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.

Those moments you're with your best other (friend or significant other) and you get all happy or excited over just living in the moment. You then notice they're just as happy or excited as you... This is the most basic form of that.
Find thoes who resonate with you and never loose them or let them go
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😊

I don't know if it's a physics term or not, but musicians call these sympathetic vibrations. It works to a lesser extent at specific frequency ratios as well.
If one fork was pitched to double the frequency of the other, it would work fairly well. If one was 2/3 the other's frequency, it would also work okay. Musically, that's an octave and a perfect 5th, respectively. Piano strings do this a lot.
I play Timpani drums. I can test how well they're tuned by singing the note I'm aiming for into the drumhead, and seeing if it vibrates. It's actually a fairly common technique.
My friend, that's awesome to put it on images; so people don't struggle to understand it. Frequency is the key for almost everithing.

Unlike tuning forks we can start as strangers on different frequencies and adapt to each other at whatever frequency we want.
Not the same concept
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.)
Destructive interference is called progressive politics.
Tonal blind spots are with 3d geometrical positioning that specifically pertain to recording room studio constructioning of dampening/reflecting/absorbing...

For first compression - it starts with optimal sound gather, then the cleanup of total gain is applied
Something similar to this is commonly used every second almost everywhere: almost any communcation media using radio waves (bluetooth, wifi, radio, tv, you name it!)

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!!!
