在日常生活中,人们常受到外界振动的影响,如车船的颠簸、机械的振动和噪音的影响等。当这些振动恰好在一定波长的范围内,虽然你既听不到也看不到它,但也能使你晕车,晕船,甚至头痛、呕吐,同样的情况也会发生在宇宙飞船中。这些都是由次声波造成的。 In daily life, people are often affected by external vibrations, such as bumps in vehicles and boats, mechanical vibrations, and noise. When these vibrations happen to be within a certain range of wavelengths, although you can neither hear nor see it, it can also make you motion sickness, seasickness, and even headaches and vomiting. The same happens in spacecraft. These are caused by infrasound waves.
