Abstract
The increasing noise pollution from aircraft poses significant challenges to both environmental sustainability and public health. This study systematically reviews two main types of aircraft noise, aircraft noise and engine noise, and assesses various approaches currently employed to mitigate two types of noise. The findings indicate that while advancements have been made in reducing noise levels, many technologies face challenges such as weight constraints, cost implications, and the need for maintenance. For instance, while sound-absorbing materials can significantly lower interior noise, their effectiveness often diminishes over time due to wear and tear. Active noise control systems show promise but require sophisticated sensors and algorithms to function optimally. The main purpose of this article is to comprehensively introduce aircraft noise reduction technology, focusing on analyzing several widely used noise reduction methods and their effects in practical applications. Through detailed discussions on fuselage design, engine noise reduction, noise shielding technology and other aspects.
