At a specific instant in time, a car, van, or truck passes near an elementary school. Individually, these noise sources generate noise levels of 40, 60, or 100 decibels (dB) at the school, respectively. Determine the combined loudness that is experienced by the school when they all pass at the same time. If traffic noise experienced by the school becomes excessive, what immediate measure(s) would you recommend mitigating the noise levels? How would you justify the cost associated with such an investment?
