目的:了解交通噪声的危害及掌握简易的观测方法。形式:交通噪声观测。美国人曾在1959年做过一次实验,用高额奖金聘请10个人站在地面上,让超音速飞机从他们头顶上10—12米处飞过,尽管他们手捂耳朵拼命躲避,还是无一幸免,最后全部被飞机噪声所“击毙”,可见交通噪声是一种看不见的谋杀。 Purpose: To understand the hazards of traffic noise and to master simple observation methods. Form: Traffic noise observation. The Americans did an experiment in 1959, hiring 10 people with huge bonuses to stand on the ground, letting the supersonic planes fly 10-12 meters above their heads, and despite their hands covering their ears desperately avoiding nothing Fortunately, all were finally “killed” by aircraft noise, showing that traffic noise is an invisible murder.
