A plane sound wave propagates along the `x` axis . The damping coefficient of the wave is `gamma=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.
