Solve the problem.Use the formula D = 10.0 log (S/S0), where the loudness of a sound in decibels is determined by S, the number of watt/m2 produced by the soundwave, and S0 = 1.00 × 10-12 watt/m2. A certain noise produces 5.1 × 10-4 watt/m2 of power. What is the decibel level of this noise? (Round to an appropriate number of significant digits.)
