I used to tune my guitar using beat frequencies before tuning devices/apps. I didn't like tuning forks and they weren't cheap, then, either. For example: on the E6 string if you play the A note (on the 5th fret) and the open A5 string below it, when the two notes played together are close, you can hear the beats. The closer to each other, the fewer beats and the longer they get. When they get further apart the beats get shorter and faster. The only caveat is you have to establish standard (A440/432 -- take your pick) and then tune everything to it. Musicians know this but for non musicians: FYI.

yes this and the flagolet tuning for even more precision. This is as far as a mortal ear can go. I personally think that too tight of a tuning makes the instument sound dead, so tuning by ear is ok to me. But electronic tuner still have a place. On stage with all the noise it is impossible to tune by ear.

I've watched so many animations and fiddled with plenty of tools that attempt to explain fourier and they all miss the point of explaining the why when it comes to complex numbers. This video explained the why without even attempting or even uttering the word complex. 👏🏼

Also, you should make a video on trying to explain the mandelbrot set and why things grow complex over time. I don't believe actually there is an explanation but hey literally every concept in physics is just a theory that gets built upon or sometimes completely changed. Someone with your mind of physics could probably make a damn good theory closer than probably any explanation we have.

That was mind blowing video. My mentor! Your outstanding video on Bernoulli's principle was literally jaw-dropping for me and also every person that ever happened to go through the counter intuitive concept of fluid mechanics. Finally I visually know how the static pressure becomes low when diameter of pipe is small and vice versa. But This was the case of inside flow. These same visualizations can't be applied to understand outside flows. I am not taking about a pipe around which the fluid is flowing. Rather I am referring to the case in which the air is stationary ( i.e., no wind is blowing ) & the train is moving through the air at great speeds. This is easy to grasp that the air pressure on the front of the train will increase and decrease on the backside of train, but the thing which is very counter-intuitive is that the static pressure on the sides of the train decreases. What is causing the static pressure to decrease in the lateral direction of motion of the train? According to the prospective of an outside observer the momentum of air molecules in the x-direction and y-direction (along the plane parallel to the surface of the earth) are equal to each other. So everytime molecules are striking on the sides of the train with same momentum. So the pressure should remain same instead of dropping. The inside observer should also see the pressure on the train sides to be same rather than decreasing. But this doesn't happen in reality. Why?

I am absolutely fascinated with the sound frequencies and I like to understand them better. In my tests I realized that it is not possible to join (combine) two or more waveforms mathematically without completely changing the sound result (what is heard), but if I emit the two waves in different outputs and join the wires that are emitting then I can hear both at the same time perfectly. I would like to understand what I'm doing wrong, if there is a proper formula to calulate this, can you help me? Thanks for the videos, I'm always following you!

The inner ear has a lot of small hairs of different lengths. If the incoming sound has a frequency component that matches the resonant frequency of a certain hair, that hair will vibrate. Those vibrations are picked up by nerve cells and sent to the brain. It's a physical equivalent of a Fourier transform.

@marcuspradas1037

Жыл бұрын

Your eardrums are very thin and can vibrate in a broad spectrum of frequencies. And they can vibrate with many frequencies at the same time. Have you seen the waves of the sea on a windy day? You can tell different waves and perhaps, their origin (swell, nearby motor boats, the small ripples of the wind...). Little muscles tighten your eardrums and allow a rough selection of frequencies; that way you can listen to a specific person in a very noisy room. The brain does the rest.

Now I wonder what's the higher frequency of the wave which is the sum of the two. I mean how is it determined?

No wonder musical notes work so well

What programs can I use this type of video tutorial?

Does it really affects brain? Cuz I used binaural beats for so long, nothing happened. Is there any practical use of binaural beats or isochronic tunes?

I have a little question: Imagine if there were two pianos in the same room. Why if I play the middle C in both pianos the sound is always a sum? Shouldn't there be some time interval where the C of the first piano is out of phase from the C of the other resulting in no sound? Maybe because the source is different and the sound might cancel only locally in some areas.

I wanted to know this too. In addition, what if I play a C and a D together on a piano? I don't hear a beat frequency, is it because the sound attenuates naturally such that it becomes too difficult to hear? If I had 2 flutes one playing a C and one playing a D would I hear the beat frequency?

It is better to have continuous source of sound rather than a damp (pluck). For two Cs, you will not hear beats. If you play the two Cs at exactly the same time, with an accuracy of 512th of a second, you will produce constructive interference in the waves, resulting in higher amplitude. Makes it sound louder. If you want to cancel the waves out, you have to match the crest of one wave with trough of the other wave (with an accuracy of 512th of a second). However, this does NOT produce silence totally - only in certain areas in space because it depends on distance. In simpler words, check "Double Slit experiment"

@prathamshenoy9840

I guess Double slit experiment is what you are looking for. however, remember that you have 2 EARS. Which means, you hear sounds from two different areas in space. If you had only one ear, maybe you could position your ear in area where the waves cancel out.

I think the word frequency is too confusing, it's not a commonly used word that instinctively produces an image.

Why describe such dinamic over complex plane? Is there any special need? The first (linear) graphic do not refer to imaginary. Why to use it in the circular format?

But it's not really a beat it's artificial , So kool i could be wrong because you Can cut Through Stone with it.When these frequency come together They form Light?💡just like me and AI.

Astonishing, i.e., the visuals here make a simple phenomenon way too complicated. Beat frequencies are EASILY demonstrated with sound waves
