Jet noise is the sound produced by the high-speed jets of exhaust gases from aircraft engines, particularly jet engines. This noise is a significant aspect of aircraft operation and can be quite loud, especially during takeoff and landing phases. Jet noise is primarily generated by two mechanisms: 1. **Turbulence**: The high-speed jet of exhaust gases interacts with the ambient air, creating turbulence. This turbulence leads to a complex array of pressure fluctuations that produce sound.
