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.
In extreme noise, the answer often is yes. The decibel scale is a logarithmic scale, not a linear scale. This means that every 3 dB drop in noise level (that is, 3 dB more attenuation in the hearing protection) reduces incoming noise by half.
