Step-by-step explanation
Step 1.
At a certain distance from the source, the sound output of a sound source can be expressed in terms of sound intensity or sound power. The sound power and intensity are proportional. The source's sound power is the product of the sound intensity and the region over which the sound energy is uniformly distributed. To convert sound power into decibels, apply the logarithmic ratio of the given sound power to the threshold sound power.
The decibel is a unit of measurement that equals one tenth of a bel. On a logarithmic scale, it represents the ratio of two values of a power or root-power quantity.
