1Hz?联想到了这篇文章,挺有意思的,供大家看着玩吧,https://www.audioholics.com/room-acoustics/bass-the-physical-sensation-of-sound
While one test found that none of the participants could sense any vibration at 1 and 2 Hz even at 144 dB, one effect that might be possible for humans at this extremely low frequency and extremely high amplitude is artificial respiration.
测试发现,即使在144分贝的振动下,所有参与者都无法感受到1赫兹和2赫兹的任何振动,但在这种极低频率和极大振幅下,人类可能感受到的一种影响是人工呼吸。
One Air Force study found decreased respiration in anesthetized animals subjected to frequencies from 0.5 Hz to 8 Hz at sound pressure levels above 166 dB, and at 171 to 173, independent respiration ceased for large dogs, with their chest being virtually motionless below 1 Hz.
The animals were not suffocating; what was occurring was the pressure waves were so large that air molecules were being exchanged between the ambient air and the lungs of the dog, so, in a manner of speaking, the sound waves were breathing for the dog.
某空军研究发现,声压级高于166分贝时,麻醉动物在0.5赫兹至8赫兹的频率下,呼吸会减弱。声压级171~173分贝时,大型犬的自主呼吸停止,它们的胸部几乎静止不动。但是,动物并没有窒息,空气分子在周围空气和狗的肺部之间进行了交换,所以,可以说,声波就是狗的呼吸。
所以,就变成“呼吸机”了,哈哈哈~~
低频对人体各部位的影响,https://zhuanlan.zhihu.com/p/615265635
最好玩的,感觉还是这个17~18Hz的“闹鬼”频率吧。
that locations that have sound emissions at this frequency can sometimes be mistaken for being ‘haunted’ for this reason.
发出此频率声音的地方,有时会被误认为是“闹鬼”的地方。
In another test, a 17 Hz tone was shown to cause anxiety in some people when it was used as an undertone in a concert performance against a control performance that did not have the undertone.
眼球的共振频率为 18 赫兹,音乐会中加入17Hz的超低音后,会引起一些人的焦虑。
