Answer:

Here L represents decibels, which correspond to an arbitrary sound wave of intensity I, measured in watts per square metre. The reference intensity I0, corresponding to a level of 0 decibels, is approximately the intensity of a wave of 1,000 hertz frequency at the threshold of hearing—about 10-12 watt per square metre.Mangnitude is used to measure the distance travelled.
