Let i0=1.0*10^-12 watt per square meter be the energy intensity of the softest sound detectable by the human ear. Let L(i)=10*log(i/i0) be the formula for the loudness of a sound, in decibels(dB), whose energy intensity is i. Find the decibel measure of the sound whose energy intensity is 8*10^-4 watt per square meter. A.80.0 dB B.89.0 dB C.98.0 dB D.107.0 dB E.116.0 dB
