A fireworks display is taking place. D1 = 500 m away from the explosion, the pressure of sound waves reaches the maximum of PPmax = 10.0 Pa. Let's say the speed of sound waves is 343 m/s. And every sound absorbs from the ground. And the air absorbs the energy of sound waves at a rate of 7.00 dB/km. Express the sound wave level in decibels as far as d2 = 4.00×103 m from the explosion.
