What are nacelles? How they help in reducing noise?

Question

Accepted Answer

Nacelles are aerodynamic structures on aircraft that enclose engines. They help in reducing noise by providing sound insulation and directing exhaust gases.

Nacelles are structures on aircraft that house engines.
They are designed to be aerodynamic to reduce drag and improve fuel efficiency.
Nacelles provide sound insulation to reduce noise generated by the engines.
They also help in directing exhaust gases away from the aircraft and reducing turbulence.
By reducing noise and improving engine efficiency, nacelles contribute to a quieter and more comfortable flying experience.

Accepted Answer

The nacelles themselves reduce sound just by being another barrier before the sound gets to you for the most part. It's there to provide airflow around engine components, better aerodynamics, protection from elements, and depending on what kind of engine it is, it "may" help with noise reduction some (Turbofan).
