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?

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.

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

Controlling Sonic Boom Loudness Through Outer Mold Line Modification: A Sensitivity Study
AIAA Scitech 2019 Forum, 2019This paper presents a sensitivity and uncertainty analysis of the under-track loudness for a low-boom concept aircraft that has been modified to include small-scale surface deformations placed along the centerline of the aircraft’s underside.
