If I understand correctly, the reason this works is that the sound that was emitted by the speaker later reaches you first on the ground because the point it’s being emitted from a point so much closer to you that it takes less time to reach you than the earlier part when the speaker was further away.

@daverotors 9 ай бұрын

If you're near a gun range and closer to the target than the guns, you can hear the bullets whistling by before the bang of the gun (as most rifles shoot at supersonic speeds). I think the issue (which was also heard in your simulation) is that the hypothetical plane continues to fly and make sounds, therefore interfering with the "backwards" music produced earlier. A bullet ends at the target and thus stops making sound, so the effect is more noticeable, even in the real world. You could improve the effect in the simulated world by having the plane stop playing music once it passes over the observer

@musicbro8225 9 ай бұрын

The question should be: After hitting the target can you hear the whistling wind from the bullet (which should be in reverse, so I guess it would start loud and fade away). I mean the rifle is not traveling faster than sound, it's the bullet. Your scenario might be a perfect way to test it because the bullet stopping inside the target would cease all sound coming from it. Not having spent any time sitting next to a target myself, I couldn't say but it sure sounds like fun :)

That's interesting! One caveat of this would be that you hear two versions of the drone after the sonic boom - one version as it's approaching (but backwards, as though it were flying away from you the way it came) and the other flying away from you normally but at half-pitch.

@musicbro8225 9 ай бұрын

The thing is though, if the source of the sound is traveling faster than the sound, then there will be no more sound once the source has past you. The sonic boom should be the last thing you hear from anything like a plane or a bullet for example (except if the bullet hits the target near to you).

@upsidedownairline9388 9 ай бұрын

@@musicbro8225 Well, no - the source is still emitting sound, and that sound will travel backwards toward you at the normal speed of sound. It's just that the sound waves will be spaced further apart than if you were standing still. At Mach 2, that's 3x as far as they usually would be.

There's a really cool point in there that was literally just a little note on the visualisation: the sound waves invert in the 4th dimension. It isn't that they're just 'flipped' in the traditional sense; it would be closer to say the waves turned inside out, which is only possible because they don't have any tangible mass. In that sense, the sonic boom just is the interference pattern of the sound waves interacting with themselves as they get inverted.

The effect can be produced with just one slit but having the two interfering lights accentuates it. The wavelength of the light interacts with the width of the slits causing a ripple effect and when the two ripples effects come together in the middle they interfere with each other, adding and subtracting rather like in phase and out of phase or harmonics. That was back when scientists were trying to prove whether light is a wave or particles; it turns out light can behave like both waves and particles.

Well, that is simply due to the fact that sound takes time to travel. It could have been moving much slower than the speed of sound, but it was so far away that it took longer to reach you than it did to pass your position. It's the same reason why echoes have a delay.

Seems like the conceptually easier way to look at this is to put the sound source at rest in the atmosphere and then move through the pressure-wave field at high velocity. Then listen to the music from the rest frame of the aircraft. This would remove or limit some of the confounding issues and it would be pretty easy to see that you encounter the waves in reverse order.

@kberg0011 9 ай бұрын

To be fair, that was the original question as well. The observer was moving at twice the speed of sound and the emitter was stationary. This does allow for the problem to be trivialized; it's far more controlled as you could then assume the observer had zero drag.

Same. My physics teachers always were boring and/or extremely quickly irritated. Just throwing a bunch of formulas at you that you have to memorise, now and then a simple boring experiment with which you have to use one of those formulas, but everything always was done in such an uninteresting way.

@Murzac 9 ай бұрын

@@MarcelNL The problem is trying to just memorize the formulas rather than trying to *understand* the formulas. Part of the reason why teaching that can be difficult is that you may lack the mathematical tools and understanding to really be taught where the formulas come from. Like the formula s = x + ut + ½at² to describe the distance traveled by an object with a given velocity and acceleration over a given time can be difficult if you just memorize it, but if you understand what ut and ½at² are and why they are there and why they look like that, it becomes much easier to remember it. But it is difficult to properly explain why it looks like that without going into integrals. So if your math studies aren't far enough that you actually understand integrals, things just get difficult to explain. Honestly, university physics was where I learned things way easier than in high school exactly because at that point I already did have the tools to properly understand what is going on. So when the teacher just started prodding into the physics of literally everything there is with the statement that when an object with velocity v travels for t seconds, it moves s meters, and then just expanded from there all the way to electrics, hydrodynamics, orbital mechanics and nuclear physics, it was actually funnily enough way easier than physics was in high school. Velocity is just the integral of position over time. And acceleration is just the integral of velocity over time. If you know that and understand what integrals are, s = x + ut + ½at² just kind of falls on your lap. That's when you *understand* rather than memorize the formula.

@MarcelNL 9 ай бұрын

I fully, FULLY understand you! Actually I often asked what the formulas were based on, and that usually would make the teachers angry: "You don't need to know that! Some scientists who are far more intelligent than you have done tests and these formulas are the results of those tests so just memorise them! You don't need to know the how or what!" Same with the Sin Cos and Tan buttons on the calculator. I asked what those buttons do exactly, and again I didn't need to know that; far more intelligent people than me have made calculations and these calculations are now under that button and I just needed to know when to push that button with certain formulas that I needed to memorise. I loved chemistry and biology; that was all easy to understand but physics I really hated. Same with what we used to call Math A and math B. Math A was very simple; straightforward understandable real life examples that you had to make calculations with. The more factors those calculations had that you had to work with, the more exciting I thought it was. Math B was again with those formulas that you just had to memorise. Obey the teacher, don't ask questions. Just follow orders. Be a drone that doesn't want to grow, just function the way you need to. @@Murzac

I’ve lived beside a busy road all my life, and always thought the sound of passing cars to be quite meditative. I’ve recently made a patch in VCV Rack to emulate the Doppler effect and inverse square law for sound intensity. It takes the perceived change of pitch and soundstage width as inputs. It then calculates the speed of the object that would create that change in pitch, and outputs individual pitch and volume CV’s for left and right channels. It’s so awesome to see someone tackle this from the sound design side of things! I might try to incorporate the sonic boom as a kick next!Keep up the great content!

@Anklejbiter 9 ай бұрын

I've done simulations in paint, and yeah, if someone is moving at these speeds, things get weird. at the speed of light coming towards you: it would look as though they are perfectly stationary, and suddenly appear in front of you. you would also see the light that reflected off of them from every point in their journey, which is a lot of light - they would appear bright. and as though they existed at every point in the journey simultaneously - pretty weird. if they were going 2c, then things get really weird - it would appear as though they teleport in front of you, and they make the journey in reverse (at .5c) to where AND when they left - all while simultaneously standing in front of you! keep in mind this would look pretty weird from their end, too - their fov would massively increase, as light that would have been coming from the side or even slightly behind them is going slower than they are, giving them a change to "catch up" with it, making it initially appear as though they are actually getting further away from their destination, even though they're doing the opposite!

@Anklejbiter 9 ай бұрын

@JDDavid 9 ай бұрын

I liked everything in these explanations except the shooting arrrows that slow down the farther they get. It works to illustrate the idea of compressing the distance betweek waveform peaks/troughs, though, so ok. but just so folks know, the sound waves keep right on going basically forever at the same speed in their surrounding atmosphere (or media more generally) as when they are first emitted. What they lose isn't velocity, but rather energy, which over time is its power. The main reason a sound wave heard at 96 dB one meter from a speaker, which is about 1/100 of a Watt of power and as loud as a 4-beer Benn, drops to inaudibility far away is because the energy in that sound wave is spreading out over an ever-larger spherical surface, like an inflating balloon getting paler and paler as the pigment particles spread out over the stretching surface area. Eventually the energy is spread so thin that the energy _per unit area_ is below the average energy from all the other noises of our world that pass through that same little bit of area, and the original sound is masked by noise. Or if you live in an utterly silent chamber (echos or no echoes) it falls below your threshold of hearing. (A small bit of power is lost in the friction of moving air molecules, but mostly, its the spreading out that makes loud sounds quiet.) But back to the arrows! OK so I say they move at a constant speed in any chosen direction, but our fast-moving bow-hunter is simply catching up to the previous arrow with each successive _forward_ shot, and shots to the rear, each successive one is shot from further away from the prior one than if the hunter were stationary in the atmosphere around her. It's still not a perfect model because real arrows shot forward by a moving bow hunter realky will go faster than her rearward shots, but sound waves all just stick with one speed moving in any/all directions. In fact if you can understand that constant speed effect, that very clear difference between shooting projectiles and propogating waves in a medium, you've nailed the origin of the Doppler effect!!
