摘要
This study presents evaluation of noise levels in urban buses. Noise exposure was evaluated in 80 buses of four models. Differences were found in noise among various bus models and among buses with different engine configurations. No strong correlations were found in year of fabrication and LA(eq). ANOVA and Tukey's test characterized conventional buses as noisiest buses and speedy buses as lowest noise inducing buses.
