(Young, ). At speeds just above Mach 1 the wind conditions, air temp and air pressure can have a significant influence on the shock waves generated by the object, and therefore the energy and propagation of a sonic boom. The impact of sonic boom needs carefully evaluated and precise noise regulations for sonic boom need to be devised.

In this context the EU integrated project HISAC (High Speed AirCraft) will try to find answers by modifications in aircraft design that limit the environmental impact of sonic boom. The sonic boom is a steady state phenomenon.

A sonic measurement program was conducted at Edwards Air Force Base. Sonic boom signatures, produced by F-4, F, F, F, F, F, SR, and T aircraft, were obtained under the flight. The leading edge of the wave or wave front is approximately spherical in shape, and the pressure disturbance propagates away from the source in a series of concentric spheres.

The speed of propagation of these waves, the sound speed, varies with the temperature and pressure of the air through which the waves travel.

In addition, the skinnier cone means that the wave is actually taking a more direct path (closer to a straight line between the source and ground) and the shorter distance will mean less dissipation. An oceanic depth sounding vessel surveys the ocean bottom with ultrasonic sound that travels m/s in seawater and finds a 10 second time delay of the echo to.

Gerald Whitham was first to systematically examine these multiple shock waves, which he called the F-function, generated by the complex nonaxisymmetrical configurations applicable to airplanes The U.S. Air Force conducted its earliest sonic boom flight test at Edwards AFB in with an F making in-flight measurements of another F Sonic booms have been generated by aircraft ever since the X-1 exceeded Mach 1 in Within a few years sonic boom was understood by aerodynamicists to be the shock wave pattern from the.
