@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.
Progress is being made toward developing an indirect vibration-based sound power method to obtain the sound power radiated from acoustic sources with internally generated noise. https://t.co/0pQa98PB0g

Acoustic radiation efficiency for rocket plumes may be less than the 0.5% previously assumed because ground reflection effects may not have been taken into account in earlier measurements. https://t.co/eimNUgGRaa

It was @BYU's Spring Break Day but not for some @BYUAcoustics faculty and students, who were hard at work measuring the sound radiation from a Balinese gamelan gong. #dedication
Just how loud is a rocket launch? Research from @BYUAcoustics can tell you after measuring sound from the recent Artemis launch and by calculating the sound levels from the Saturn V launch.
Great story from @kosmofoto.

Hardware limitations can pose challenges meeting requirements for high-fidelity measurement of sonic boom waveforms. This letter describes an engineering method that can extend effective hardware bandwidth. https://t.co/bgWMRNLkea

We’re glad to have Dr. Grant Hart presenting his research on rocket noise! 🚀
Dr. Hart has worked at BYU since 1985 and spent most of his time as a plasma physicist, and recently decided to pick up rocket science!
"How loud was the world’s most powerful rocket that blasted off from the Kennedy Space Center last November?
BYU professor of Physics and Astronomy Kent Gee can tell you: about 136-137 dB...nearly a mile away from the launch!"

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"

This new POMA presents the development of an “acoustic tent” for measuring the radiated sound power from devices with complex or hidden geometries using a vibration-based sound power method.
