1. During a fireworks show a rocket explodes above a listener 1km high
with respect to the ground while the sound produces 520watts of power.
A group of people talking and they all produce sound levels of the same
magnitude at the listener’s position. The combined level when all four
talks at once is 72dB. If a man is shouting producing SPL of 82dB and is
160m away east side of the listener’s position;
a. What is the total SPL meter reading of the three different sound
sources, the rocket explosion, the man shouting, and the group of people talking at the listener’s position?
Assuming that the group of people talking is at south of the listener.
T=30°C
