At This Many Decibels, A Sound Would Destroy The Universe

NASA estimates the mass energy of the universe at 4x10^69 joules, a number that is considerably smaller than the energy created by 1,100 decibels of sound. Converting the energy of 1,100 decibels to mass yields 1.113x10^80 kg, meaning that the radius of the resulting blackhole's event horizon would exceed the diameter of the known universe.

Key Facts In This Video

  1. Zero decibels is the sound of a mosquito ten feet away, and 65 decibels is about a regular speaking volume. 00:28

  2. At 195 decibels, there is no longer a sound wave because it becomes a shockwave. 00:55

  3. What you hear when a whip cracks is the tip of the whip breaking the sound barrier. 01:58
