Study: SpaceX Starship's Sonic Boom Risks Structural Damage

A study by Brigham Young University, published in JASA Express Letters, measured the sound levels of SpaceX's Starship during its fifth test flight, revealing it to be significantly louder than other rockets, including the Falcon 9 and NASA's Space Launch System (SLS). The Starship's launch noise was found to be ten times greater than Falcon 9 and four to six times louder than SLS, with the sound at 10 km distance comparable to a rock concert. The study suggests that the arrangement of rocket nozzles may contribute to the increased loudness.
