    It would have helped if you wrote down some equations, that way we wouldn't need to search for them, just a thought. I thin this one is correct:

    β(dB)=10log₁₀(I/I₀), where I₀=10^−12W/m2 is a reference intensity

    β(dB)=10log₁₀(11.3/10^−12) = 130.5308

    3 Sigfigs: 131 db

    SI = 10 LOG (1.13*10^13 ) = 130.5 dB
