You measure the sound level at a distance of 40m from the rail line of a busy road. It is known that the noise generated by traffic at a distance of 6m from the center line of the road is 85 dB. On the opposite side of the road, at a distance of 120m from you, there is a rock crusher with a sound power level of 123 dB. Evaluate by calculating what the measured sound level could theoretically be at most. Air or ground damping is not taken into account in the calculation. There are no obstacles in the way of the sound.
