The loudness of a sound of intensity x, measured in watts per square meter, is defined as L(x) = log (
), where xo = 10-3.A particular Boeing 747 jetliner produces noise at a loudness level of 113 decibels. Find the intensity level (round to the nearest hundredth) in watt per square meter for this noise.
What will be an ideal response?
