The loudness level at a distance \( \mathrm{R} \) from a long linear source of sound is found to be \( 40 \mathrm{~dB} \). At this point, the amplitude of oscillations of air molecules is \( 0.01 \mathrm{~cm} \). Then find the loudness level \& amplitude at a
\( P \) point located at a distance '10R' from the source.
