Are you aware of the different intensity levels of sounds? If for no other reason than for the safety of your hearing, you need to get acquainted with the information available in this decibels unit.
Intelligence is like a river; the deeper it is, the less noise it makes; and tennis is a game that can't be played without raising a racket.
He who establishes his argument by noise and command, shows that his reason is weak.
All noise is a waste. So cultivate quietness in your speech, in your thoughts, in your emotions. Speak habitually low. Wait for attention and then our low words will be charged with dynamite
When the eardrum vibrates, it sets in motion a chain of tiny bones in the middle ear, the names of which we [should] have learned in school: the "hammer" (malleus), the "anvil" (incus), and the "stirrup" (stapes).
The stirrup, the smallest bone in the human body, weighs about 1/2,500 of an ounce.
Decibels measure sound intensity at any particular frequency. Thus, a whisper from four feet away in a quiet room ranks at about 30 decibels, normal conversation about 60 decibels, a rock band 120 dcibels, and a shotgun 140 decibels.
