happens when a source travels faster than the speed of sound

continuous phenomenon
can be heard when the receiver intersects the “cone” of sound

$$\sin(\alpha)=\frac{v_{\text{sound}}}{v_{\text{object}}}$$
$\frac{v_{\text{sound}}}{v_{\text{object}}}$ is the inverse of the Mach number → faster the plane, the more pointed to cone

N-wave

amplitude is dependent on the amount of air moved:
larger aircraft → louder sound

sonic boom causes public concerns (effects on hearing and general distribution of peace) as well as possible damage to structures

supersonic flight is prohibited above land → makes supersonic transport (SST) unviable
