2 domain-specific abstractions whose origin domain is Aeroacoustics.

• Lighthill's eighth power law — An aeroacoustic scaling law stating that far-field sound power from compact low-Mach turbulent flow scales with the eighth power of characteristic velocity.
• Sonic boom — The impulsive sound heard when shock waves generated by supersonic motion pass an observer, often exhibiting a characteristic pressure-rise and fall signature.
