1. When Washingtonâs father Augustine died in 1743, George Washington became a slave owner at the early age of eleven. In his will, Augustine left his son the 280 acre family farm near Fredericksburg, Virginia. In addition, Washington was willed ten slaves.
On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB.
Therefore, a sound intensity of 20 dB is not twice as loud as a sound intensity of 10 dB, but is 10 times as loud, and a sound intensity of 30 dB is 100 times as loud as a sound intensity of 10 dB. Similarly, a sound intensity of 50 dB would be 10,000 times as loud (10 x 10 x 10 x 10) as a sound of 10 dB. This is how the decibel scale works. It is totally unlike the linear percent scale. Now lets see the fallacy of trying to compare this âfunnyâ decibel scale to the percent scale.
