acoustic shadow的意思|示意

'

Acoustic shadow is an area where sound waves are blocked either by an obstacle or by distance. It can refer to a zone of silence that is created by an obstacle in the path of sound waves, or to a zone where sound waves fail to reach because of atmospheric conditions or physical distance.

在声波被阻碍或距离所阻隔的地区，就可以称为声影。声影有时可指声波被障碍物所阻挡所形成的沉默地带，有时可指因大气层情况或距离问题，声波无法传入的地带。

An example of acoustic shadow is a zone of quiet created by a person standing between a sound source and a listener. The person’s body blocks some of the sound waves, resulting in a zone of quiet around the person. This effect is used in studios to reduce the amount of sound that reaches the recording equipment.

一个关于声影的例子就是：人站在声源和听众之间时，会形成人类身体所阻挡的声波，从而形成周围一片宁静。这种效果也用于降低影响录音设备的声音量。

Acoustic shadow can also refer to a zone where sound waves do not reach due to distance or atmospheric conditions. Acoustic shadow can occur over long distances, such as when sound waves fail to reach a distant location due to the curvature of the Earth or other obstacles in the path of the sound waves. In addition, acoustic shadow can be caused by a temperature inversion in the atmosphere, which can cause sound waves to be blocked and not reach their destination.

声影也指远距离或大气层环境使声波无法传出的区域。声影可能出现在远距离的地方，比如由于地球曲率或声波传播路径中的障碍物，使得声波无法传到某个远处的地方。此外，大气层中温度反转也会导致声波被阻挡而无法到达目的地。

In conclusion, acoustic shadow is an area where sound waves are blocked either by an obstacle or by distance. It can refer to a zone of quiet created by an obstacle in the path of sound waves or to a zone where sound waves fail to reach due to distance or atmospheric conditions. Acoustic shadow can have significant effects on communication and sound recording, and understanding its effects can help people to better understand and control sound.
