The sound of a sonic boom depends largely on the distance between the observer and the aircraft shape producing the sonic boom. A sonic boom is usually heard as a deep double "boom" as the aircraft is usually some distance away. The sound is much like that of mortar bombs, commonly used in firework displays. It is a common misconception that ...
The sonic boom associated with the passage of a supersonic aircraft is a type of sound wave produced by constructive interference. Unlike solitons (another kind of nonlinear wave), the energy and speed of a shock wave alone dissipates relatively quickly with distance.
A sonic boom is a shock-wave, or pressure disturbance, caused by the movement of the plane through the air, much like the wave produced by the bow of a ship as it moves through water: just as the bow wave is produced for the entire journey of the ship, so the sonic shockwave occurs throughout the duration of a supersonic flight.

Overpressure psi (kPa; bar) Effect on buildings and people within 1 (6.9; 0.069) Window glass shatters; Light injuries from fragments occur; 2 (14; 0.14) Moderate damage to houses (windows and doors blown out and severe damage to roofs)
A common analogy is the sonic boom of a supersonic aircraft. The sound waves generated by the aircraft travel at the speed of sound, which is slower than the aircraft, and cannot propagate forward from the aircraft, instead forming a conical shock front. In a similar way, a charged particle can generate a "shock wave" of visible light as it ...

The Busemann biplane is a theoretical aircraft configuration invented by Adolf Busemann, which avoids the formation of N-type shock waves and thus does not create a sonic boom or the associated wave drag. However in its original form it does not generate lift either. A Busemann biplane concept, which provides adequate lift, and which can reduce ...
A sonic boom produced by an aircraft moving at M=2.92, calculated from the cone angle of 20 degrees. Observers hear nothing until the shock wave, on the edges of the cone, crosses their location. A Mach wave propagates across the flow at the Mach angle μ , which is the angle formed between the Mach wave wavefront and a vector that points ...
