airborne noise 的英标分别为:
airborne ['eərbɔːn] :/eərbɔːn/,发音时,/e/音发得稍微重且长。
noise ['nɔɪz] :/nɔɪz/,发此音时,/n/音要发清晰。
airborne noise 的意思是“空中传来的噪音”。
分别的用法:
1. 表示时间上的分离,如“分别了很长时间”。
2. 表示空间上的距离,如“相距很远”。
3. 表示抽象的离别,如“心情的分别”。
分别的发音:/'viːn/。
分别的记忆:分(fēn)开(bàn)后(rèn)就是(wài)分(fēn)别(bié)。

气动噪声是一种空气动力噪声,是飞机在空中飞行时,空气与机体表面产生压力和声能的作用,从而产生振动,并通过空气、机体和结构向周围环境辐射的噪声。
气动噪声的产生需要具备两个条件:一是要有压力变化的气流,二是要有能够将这种压力变成声能的表面。比如飞机的机翼、尾翼、发动机排气管等部位都容易产生气动噪声。气动噪声属于一次噪声,它不仅传播距离远,也容易在近场区产生巨大的噪音,因此对气动噪声的控制和利用也是航空器设计和环保部门关注的重点。
Airborne Noise Management: A Key Component of Environmental Protection
Airborne noise, whether from transportation, industrial processes, or other sources, is a pervasive problem that can have a significant impact on human health and quality of life. This article explores the various aspects of airborne noise management, including its causes, effects, and potential solutions.
Firstly, we need to understand the sources of airborne noise. Transportation, including aircraft, automobiles, trains, and ships, is a significant contributor to noise pollution. Industrial processes, such as manufacturing facilities and power plants, also generate significant noise. Other sources include construction activities, lawnmowers, and power tools. Each of these sources has its unique characteristics and challenges in terms of noise control.
Secondly, airborne noise has a negative impact on human health. Exposure to high levels of noise can lead to hearing loss, cardiovascular issues, stress, and sleep disturbance. These effects can have long-term consequences on individuals and society as a whole.
To address these concerns, it is essential to implement effective noise management strategies. One approach is to reduce the amount of noise generated in the first place by implementing soundproofing measures in industrial facilities and using quieter equipment in transportation industries. Another strategy is to provide noise-reducing environments for individuals who are exposed to high levels of noise, such as through earplugs and soundproof rooms.
Moreover, sound insulation measures are crucial in reducing noise pollution. These measures include installing soundproof walls, ceilings, and floors, as well as using soundproof windows and doors. Additionally, strategically placing trees and vegetation can also help absorb noise and reduce its impact on the surrounding environment.
Furthermore, enforcement of noise regulations and policies is essential to ensure that noise pollution is properly addressed. Governments and regulatory agencies should take a proactive stance in enforcing noise limits and imposing penalties on those who violate them.
In conclusion, airborne noise is a significant environmental concern that requires effective management strategies to address its negative impacts on human health and the environment. By implementing soundproofing measures, providing noise-reducing environments for individuals exposed to high levels of noise, and enforcing noise regulations and policies, we can significantly reduce airborne noise and improve the quality of life for all.
