The loudest sound ever recorded are rock concert speakers.
Zero dB is the quietest sound that may be heard by the average of a group of young men who have not been noise exposed. By definition, one half of these will be able to hear a quieter sound, and the other half will be less sensitive. Nowadays, these limits are more precisely defined in terms of physical units. Some animals hear at a different sensitivity to us, and over a different frequency range.
194 dB (decibels) is the loudest sound on Earth ever. Some people say that the eruption of Krakatoa in 1883 was the loudest sound ever, being heard at 5,000 kilometers away! That eruption was around 180 dB!
Nothing. No movement. Don't think of the word "nothing" as literally being nothing. It is something. Nothing IS being or doing something.
