Question: A plane sound wave propagates along the x axis. The damping coefficient of the wave is = 0.0230 m-1. At the point x = 0

A plane sound wave propagates along the x axis. The damping coefficient of the wave is γ = 0.0230 m-1. At the point x = 0 the loudness level is L = 60 dB. Find:
(a) The loudness level at a point with coordinate x = 50 m;
(b) The coordinate x of the point at which the sound is not heard any more.
