Find the number of decibels for the power of the sound given. Round to the nearest decibel.

Question

A rocket engine,
2.37 cross 10−5
watts/cm2

Answer 1

The usual reference level is 10^-12 W/m^2

Here, you have 2.37*10^-5 W/cm^2 = 2.37*10^-1 W/m^2

The dB level is thus

10 log(2.37*10^11) = 10*11.37 = 113.7 dB
