The sound level, B, in decibels (dB), of a sound with an intensity of / is calculated in relation to the threshold of human hearing, Io, by this
equation.
B = 100g(1)
The threshold of human hearing is
watts/meter?
10-12
The sound level of a jet plane is approximately 140 dB. The intensity of the sound of a jet plane is approximately
(A. 1,000 B. 10 C. 100 D. 10,000) watts/meter^2?
