Seismic detection of sonic booms [PDF]
The Journal of the Acoustical Society of America, 2002 The pressure signals from a sonic boom will produce a small, but detectable, ground motion. The extensive seismic network in southern California, consisting of over 200 sites covering over 50 000 square kilometers, is used to map primary and secondary sonic boom carpets.

Improving low-frequency response of sonic boom measurements through digital filtering.
JASA Express Letters, 2023 High-fidelity measurement of sonic boom waveforms requires microphones and data acquisition hardware with flat frequency responses extending below 1 Hz. Hardware limitations can pose challenges meeting these requirements.

Sonic boom reflection over urban areas.
Journal of the Acoustical Society of America, 2022 Sonic boom propagation over urban areas is studied using numerical simulations based on the Euler equations. Two boom waves are examined: a classical N-wave and a low-boom wave.

Sonic boom reflection over an isolated building and multiple buildings.
Journal of the Acoustical Society of America, 2022 Sonic boom reflection is investigated over an isolated building and multiple buildings using numerical simulations. For that, the two-dimensional Euler equations are solved using high-order finite-difference techniques.

Initial comparison of a Falcon-9 reentry sonic boom with other launch-related noise
Proceedings of meetings on acoustics, 2022 A downside of landing first-stage boosters of orbital-class launch vehicles, such as the Falcon 9, is the sonic boom associated with reentry and landing. To assess the potential impact of these sonic booms and compare them to launch and landing operations,

Deep learning for inverse design of low-boom supersonic configurations
Advances in Aerodynamics, 2023 Mitigating the sonic boom to an acceptable stage is crucial for the next generation of supersonic transports. The primary way to suppress sonic booms is to develop a low sonic boom aerodynamic shape design.

Hierarchical optimization method of supersonic low sonic boom configuration
Hangkong gongcheng jinzhan, 2023 Sonic boom suppression is a key technology that must be broken through in the development of a new generation of supersonic civil aircraft. The reasonable design of configuration parameters can make the aircraft have good sonic boom characteristics.
