概括
噪音屏障减少了交通噪音的暴露,但并不总是减少居民的烦. 较大的噪音降低与较大的报道降低的烦相关,但其他因素影响知觉.
科学领域:
- 环境科学 环境科学
- 声学 声学 在声学方面
- 城市规划 城市规划
背景情况:
- 噪音屏障是常见的路边干预措施,以减轻交通噪音.
- 它们对社区观念和生活质量的影响仍然未得到充分研究.
研究的目的:
- 评估噪音屏障对居民对噪音烦和生活质量的主观感知的影响.
- 调查客观降低噪声暴露和主观反应之间的关系.
主要方法:
- 在三个带有噪音屏障的住宅区和一个参考区域进行纵向研究.
- 目标噪声暴露测量 (声学测量,噪声建模).
- 通过社会声学调查进行主观评估 (噪音烦,生活质量).
主要成果:
- 噪音暴露 (Lday) 在障碍物附近减少了4.4-11.7dBA.
- 在这三个案例中,只有在其中一个案例中观察到噪音烦的直接减少.
- 较大的噪声暴露减少与报告减少烦的可能性更高有关.
结论:
- 噪音屏障在减少烦方面的有效性并未得到保证,并且取决于各种背景因素.
- 客观的降噪并不总是转化为感知到的降噪.
- 没有发现对健康,集中力或睡眠等其他生活质量方面有重大影响.

Barriers to Effective Communication I
8.8K
A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...

Sound Waves: Interference
3.7K
Sound waves can be modeled either as longitudinal waves, wherein the molecules of the medium oscillate around an equilibrium position, or as pressure waves. When two identical waves from the same source superimpose on each other, the combination of two crests or two troughs results in amplitude reinforcement known as constructive interference. If two identical waves, that are initially in phase, become out of phase because of different path lengths, the combination of crests with troughs...

Design Example: Alignment of a Road Line Using GIS
47
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...
