The sound level of a jet plane is approximately 140 dB. The intensity of the sound of a jet plane is approximately ___ watts/meter^2.
0.0001
Select the correct answer from the drop-down menu.
The sound level, β , in decibels (dB), of a sound with an intensity of I is calculated in relation to the threshold of human hearing, I_0
, by this equation.
β = 10log (I/I_0
The threshold of human hearing is 10^-12 watts/meter^2
