Sonic Boom Measurement

Traditional approaches to distributed measurements often involve significant costs in both capital equipment and labour. To capture sonic boom pressure time histories in detail, you need accuracy, flexibility and reliability in your test equipment.

Only GRAS can offer you measurement microphones and acoustic systems so you can collect high quality data while reducing test labour costs.

FAQ for Sonic Boom Measurement

What is a sonic boom?
A sonic boom is a loud shockwave sound created when an aircraft travels faster than the speed of sound, producing rapid pressure changes in the air heard on the ground. 

Why are sonic booms important in aerospace testing?
Sonic booms help engineers understand shock-wave behavior, validate supersonic designs, and assess community noise impact to support safe and compliant high-speed flight. 

What causes a sonic boom?
A sonic boom is caused by shock waves forming as an aircraft compresses air faster than sound speed, creating a continuous pressure wave that travels outward in a cone. 

How are sonic booms measured?
Sonic booms are measured using high-precision acoustic sensors and microphone systems capable of capturing wide frequency and dynamic pressure ranges to record accurate shock-wave signatures.
