Question

Find the number of decibels for the power of the sound given. Round to the nearest decibel.
A rocket engine, 2.37 x 10−5 (10 to the -5 power) watts/cm2(squared)

Answer 1

I=2.37*10^-5 watts/cm^2=Sound Intensity
level.

Io =10^-16 W/cm^2 = Reference sound Intensity level.

db = 10*Log(I/Io)
db = 10*Log(2.37*10^-5/10^-16) = 114
