Disturbances of sleep by sonic booms
Science of The Total Environment, 1974After a pilot study (two subjects, 19 nights), we tested two different subjects during 57 nights, administering sonic booms (1 mbar, 300 msec; sound level in the bedroom 80–85 dBA and recording EEG and peripheral blood volume. After five nights without noise, 35 nights with either two or four sonic booms (alternately) were applied.

SONIC BOOMS are explosive sounds that occur without warning. Sometimes annoying because of their startle effects and their ability to shake buildings, these sounds pose a unique problem for the orderly development of high-speed air transport. Although booms from military aircraft are widely observed around the world, the real concern is for proposed ...

Sonic Boom Simulation for Boom Carpet Determination
The Journal of the Acoustical Society of America, 2021The Institute of Air Transportation Systems in Hamburg, Germany, researches methodologies for optimized supersonic flight routing that prevents the (primary) sonic boom from reaching the ground. The sonic boom shall either be cut off vertically or laterally.

The thunderclap you hear when a supersonic plane flies overhead is the signal to you that the air is getting out of the way of the plane. It is called "sonic boom." This violent signal is a shock wave. What is a shock wave? When does a shock wave occur? Can the sonic boom be eliminated by some new discovery?

There have been many attempts to reduce or eliminate the sonic boom. Such attempts fall into two categories: (1) aerodynamic minimization and (2) exotic configurations. In the first category changes in the entropy and the Bernoulli constant are neglected and equivalent body shapes required to minimize the overpressure, the shock pressure rise and the ...

SONIC boom is the name which has been given to the sound heard on the ground immediately following the passage of an aircraft overhead at supersonic speeds. This sound, which has been compared to nearby thunder, results from the passage of the aircraft's shock‐wave field over the observer.

The Sonic Boom Attenuator is a device designed for use with supersonic aircraft wherein a laser beam is shone down the leading edge of a short, rigid, straight, thin wing, heating thus rarefying the air before it passes over and under the wing. In this manner, the compression (which results from the rarefication) occurs more slowly as the relative wind
