Answer to Question #220837 in Physics for Lizzy

Question #220837

What is the interference in Wm/2 of 85dB sound?

Expert's answer

The intensity level of the sound

"\\beta=10\\lg\\frac{I}{I_0}"

So, the intensity of the sound

"I=I_0*10^{\\beta\/10}\\\\=10^{-12}*10^{85\/10}=3.2*10^{-4}\\:\\rm W\/m^2"
