Applications. Decibel Level Decrease with Distance: The decibel decrease \(G\) when moving from a sound source at a distance \(d_{n}\) to a distance \(d_{f}\) is given by $$ G=20 \log _{10} \frac{d_{f}}{d_{n}} \mathrm{d} \mathrm{B} $$ Find the decibel drop when moving twice as far from a sound source.
