The formula for measuring sound intensity in decibels D is defined by the equation D = 10 logs (I/I^0 UNDER) where I is the intensity of the sound in watts per square meter, and I UNDER 0= 10^-12 is the lowest level of sound that the average person can hear. How many decibels are emitted from a jet plane with a sound intensity of 8.3· 10² watts per square meter?
