NASA Turning Down The Volume On Rocket Noise
A 5-percent scale model, including solid rocket motors, of NASA’s Space Launch System (SLS) is ignited to test how low- and high-frequency sound waves will affect the rocket on the launch pad. The data collected from the tests will be used to help direct and verify the design of the rocket’s sound suppression system.
