A binaural audio recording of the Falcon Heavy liftoff, and the 6 sonic booms of the returning boosters. Amazing raw sounds.

this was cool
NotADutchman
This is too much for me. It’s like rocket science.
CanadianOneDollarCoin
Dude you can’t just say binaural anymore.
arePi
man that sounds awesome!
GadenKerensky
It sounds like a rapid cannon barrage.
Dyslexicbirch
Wow that was neat
KiltedinSeattle
Neat. My GF was wondering what I was "Whoa"-big about. Not telling her.
XxPiiJayxX
Soooo what happened to the main boosters????
dryad909
Crashed into the sea I think...

I'll be back to listen to this tomorrow.
Duros62
That was WICKED!

Thanks...that was fantastic, much clearer on the triple booms
RefAtty
Very cool.

Looks like the forerunners are coming back guess it's that time to fire the halo rings again
SlavicMusk
Where’s the audio?

Ok

The sonic booms start at: 06:47

First and only time for many people to be happy about two missiles coming right for them.

Only got inears but i get the vibrations. I think i'm gonna travel to Cape for the Next Launch just to witness one in RL.

This is even better if you watch Smarter Every Day on a surround sound entertainment unit.
dryad909
Yeah I should have included surround systems too ;-)

But binaural audio is specifically made for stereo headphones, it records how the sound travels around your shoulders and head.
Hevdelurn
I watched this with headphones and some nice speakers. You need to get some good speakers and crank them up, you will not be disappointed.
flyingdutchfrenchman
Yeah it might be impressive, but using anything else than stereo headphones kills the spatialization of the sound
Bastorizzel
Favorited to watch at home with my Nubert NuLine AW-1100 :D

I did not know this existed.

nice

I got a notification from smarter every day. Imagine being one of those 20 photographers!
mattywgtn
When those sonic booms hit. Omg
auserwithaname
That waa absolutely insane!
Hamncheezsandwich
Usually, this is called "stereo".
PokemonNumber351
It's only binaural because of the mic that is used. Surround sound works too.
Higure
There are two audio channels, so sure. But it's more than that. The mics used are made to replicate the sound distortions of an outer ear 1/
Higure
and a head and two shoulders, so if you listen to it with headphones, the soundwaves that hit your ear drum are as close as we can make 2/
Higure
them to how it would've been if you had actually been there. That means you get an uncanny sense of direction, for instance. 3/3
Hamncheezsandwich
Ok, I just read up on it. Thanks. Learn something new every day.

I guess you were one of today's 10 000 ^^ https://xkcd.com/1053 (At least if you're American. If not, the number will probably be different)

Why are the sonic booms happening after the boosters land? I've only heard sonic booms when an object surpasses mach I mph!?
SirNigelThornberry
light travels at 3x10^8 m/s where as sound is 333 m/s. so the booms are experienced some time after. This also can be noticed with fireworks
iatha
Because of distance. Sound only travels so fast, and so you can see them land before the shockwave gets to where they were recording.
MetaSomma
NSATailoredAccessOperationsUnit
Light travels faster than sound, so you see before you hear it. Same thing with aircraft at a distance
JimStarluck
Same reason the thunder comes after the lightning -- takes time for the sound to reach you.
neithermenoryou
/1 The engine causes a sonic boom because of the force the rocket blast creates when it starts burning to slow down the rocket, the fins
neithermenoryou
/2 cause their own sonic booms because when they get deployed they also still go faster than mach 1 for a couple seconds.
neithermenoryou
/3 And you hear all of that after the rocket lands because sound travels at 343m/s and the pad is ~14,630km away, so takes ~43 seconds
neithermenoryou
God damn it, the pad is 14.63km away, so 14,630m.
Ivajl
As a European, you were right the first time.. 14,63km ;-)
SwedishRationalist
Why does the takeoff sound like a continuous stream of distinct explosions rather than just a steady "BWOOOOSH!!1"?
edalton454
27 engines = 27 continuous explosions.
Bunsen
I think this is due to nonlinear steepening -- a high-amplitude sound wave compresses the air enough that the speed of sound in the ...
Bunsen
compressed region is significantly faster than in the rarefied region, so the peak overruns the trough and creates a sharp shock. A lot ...
Bunsen
of that would be happening in and near the exhaust plume, along with other hypersonic turbulent craziness that I don't even know about.
