@BYU PASCAL students are headed back from a highly productive two days presenting their research and visiting with scientists @NASA_Langley. We are trying to improve the upcoming acoustical measurements of X-59, the first quiet supersonic aircraft.
Dear @KelloggsUS,
What do @ricekrispies and @NASA_SLS sounds have in common? They both crackle.
We found the noise from the world's most powerful rocket 5 km away to be equal to about 40 million bowls of cereal.
Just thought you'd like to know.

It's out! Here is the link to our #openaccess publication about the noise from the @NASAArtemis I launch of @NASA_SLS. Among other findings, we see a need to revise noise models developed prelaunch.

@NASA@BYU@Erdayastronaut@DJSnM
Our article describing initial findings on the @NASA_SLS@NASAArtemis I launch noise comes out later today in @ASA_JASAEL.
While we're waiting - relive the adventure had by @BYU students and faculty members!

Sonic boom measurements require hardware with response good to 0.1 Hz, but the mics have low sensitivities/high noise floors. This @ASA_JASAEL describes a digital filtering method to enable use of lower noise mics with higher corner frequencies.

@DSP_fact A great explanation, except it's generally not an energy. It's the signal's complex amplitude (magnitude & phase) at each frequency. Energy often requires magnitude-squaring of the Fourier transform, X_k. Calling a Fourier spectrum an energy spectrum needlessly confuses students.
SOUND ON 🔊
Tasked with measuring the sound of the world’s most powerful rocket, @BYU_PASCAL was onsite for the epic @NASAArtemis I launch.
"You only get one shot. When that rocket launches...if you're not prepared you get nothing"

@KentLGee Should inform students of that. It’s just a box to check or not and I didn’t pay much attention to mine. Didn’t know it mattered and didn’t think it’d make a difference, and I’d never heard anyone talk about it.
3) Awards. A @ASA_JASAEL paper on wind noise was an Editor's pick: https://t.co/vWxqMtmM26 Another on sonic boom measurements made the journal cover: https://t.co/dhfFAmPwHz
And @TaggartDurrant won a prize for a @ASA_POMA on Falcon-9 sonic booms: https://t.co/DMTAmD6diu
Our measurements of the #Artemis I launch were featured in a @BYU video. They captured so well the experience in 3 and a half minutes. Check it out!

Listen to @BYU undergrad @TaggartDurrant talk about his rocket launch noise and sonic boom research, which won an @ASA_POMA student paper prize. Way to go, Tagg!
