The power of 100 loudspeakers

  The megaphone is something that we believe we have seen in everyday life and are used to it, and when the height of the sound exceeds a certain decibel, it will have a huge lethal effect, not only on the human ear, but also can affect other things, for example, when the sound is loud enough, even can break the glass, And today for everyone to bring it, is a foreign brother of an experiment, the content of this experiment is also very simple, is to play a source, through a hundred loudspeakers to amplify, to see the final resulting volume can not break the glass.

  First took out a megaphone, aimed at the glass bottle, and then the result is no suspense, the glass bottle is not moving, and then the foreign brother began to slowly increase more horns, from a horn slowly into two, five or more, when the number of horns reached about five, The foreign brother and his friends who did the experiment could not bear the volume, directly with the earcup, and the number of horns is still increasing, this time, the horn has increased into a long row, the noise has been unbearable, and the long glass is still motionless.

  We said at the beginning that the horn was going to be increased to 100 at the end, but when the horn was placed in a long row of 100, the penetration of the noise could have been passed away, and the glass was still safe. Isn't that the volume that doesn't do anything lethal?

  Finally, the two foreign brother solder a different way, no longer one by one place the horn, but directly around the horn into a circle, the glass in the center, with a crisp bang, the glass finally broke. It seems that you want to break the glass with a voice, it is not an easy thing, what do you think, welcome to leave a message in the comments area to discuss.
