The sonic boom problem - Katerina Kaouri

View full lesson: http://ed.ted.com/lessons/what-causes-sonic-booms-katerina-kaouri

Objects that fly faster than the speed of sound (like really fast planes) create a shock wave accompanied by a thunder-like noise: the sonic boom. These epic sounds can cause distress to people and animals and even damage nearby buildings. Katerina Kaouri details how scientists use math to predict sonic booms' paths in the atmosphere, where they will land, and how loud they will be.

Lesson by Katerina Kaouri, animation by Anton Bogaty.

Last night I also heard a sonic boom, that's why am here

A whiplash, too, is actually a sonic boom.

What’s a kilometer?

Finally understand it now. Just watched a video about NASA & Lockheed Martin developing X-59 Quesst and how they are tying to eliminate the sonic boom

I mean the tips of whips produce a sonic boom every time a whip is snapped. Meaning we were supersonic long before we were even airborne.

So the pilot hears nothing

There is no problem if aerodynamics is considered in the design of an aircraft or missile or rocket. The shockwaves are generated by shapes and can be released via design-stage mitigation. Release of forces is a Chinese speciality. Controlled release of forces is an art. Barometric pressures generate heat due to air friction. Hypersonic is when a poorly designed aircraft burns itself to dust. Fonsidering barometric pressures of Q4 2023. Missiles are silly and planes at supersonic are silly. The deliberate pollution generates heat due to aerodynamic inefficiency points and near supersonic/hypersonic(mach3) cross over points. 330m/s is only applicable at sea level barometric altitude and not always true. Missile algorithms need updates or world laugh at anything supersonic and above.

I'm a bit confused about the explaination. The explainaition says that it's the travelling sound waves that get compressed until they suddenly lose that compression since the new sound waves appear in front of the old sound waves after braking the sound barrier, and not behind them, as usual when the plane travels below the speed of sound. But then the explainaiton goes on to say that it's the pressure formed at the front of the plane which creates the initial boom. So, is it just the pressure, is it the sound waves or both? Would I still hear a sonic boom if the plane didn't make any sound?

Imagine reaching the speed of light, ( i know it's impossible . Just saying )

nah you aint foolin me. I KNOW thats the Minecraft water sound at 1:49

The sound barier is 1230kph

Km/h.?? I’ve travelled at 1,420mph in luxury. Awesome

i heard a minecraft water sound effect

1:49 So we're just gonna ignore the Minecraft water sound? 😂

If two persons is standing like 50 ft away. Will they hear each other sonic boom ?

@bigdreamsrecords5614
2023-11-08T16:21:07Z

Yah well sonic boom occurs when we BREAK the sound barrier but what would happen if we crossed the sound barrier? Will we achieve the speed of light?

@johnsiangpajing2990

I think a crack of a whip is also a sonic boom.
