A firework charge is detonated many metres above the ground. At a distance d_{1}=550 m from the explosion, the acoustic pressure reaches a maximum of ΔP_{max}= 10 Pa. Assume the speed is constant at 343 m/s throughout the atmosphere over the region considered and the ground absorbs all the sound falling on it. Assume that the density of air 1.2 kgm^{-3}. What is the sound level at a distance of d_{2}= 4.30 x 10^{3}from the explosion?
