To understand how this really loud noise, we give a few examples.

The rustling of leaves in the wind - it's the sound at 15 decibels - it is barely audible. It is a distinct sound - a normal conversation, the noise level from which - about 45 decibels. A loud cry and laugh - it is quite noisy (75 decibels).

At the sound of 160 decibels at a man torn eardrums and even lung tissue (due to the resonance of sound in the lungs), the sound is 200 decibels - deadly.

So, the loudest sound a 210-decibel, created in 1965, was obtained by the reflection of sound waves reinforced concrete test bed of 14 m and 18 m deep foundation. The mine was built to test the rocket "Saturn 5" in Alabama.

The sound of this power allowed to drill holes in hard materials, and its echoes were heard within a radius of 160 kilometers from the test area.

By the way, the loudest scream that could give the man was equal to 129 dB.
