Noise Levels of Selected Construction Tasks

Abstract Current data regarding construction noise exposure are confusing, and their implications are not well understood. This is due in part to measurement challenges. Using standard dosimetry for measuring noise levels in the construction industry is inadequate due to the multitask, variable environment of the construction worker. This study used a task-based approach to collect noise exposure data on selected construction tasks. Results of this effort include the identification of additional tasks or tools producing high levels of noise that had not been previously identified by trade representatives. Noise levels for a variety of tasks were used in the development of a computer-based training program designed for three construction trade groups: roofers, laborers, and carpenters. Providing construction workers with information on noise levels specific to their trades can improve the effectiveness of hearing conservation education by making the information relevant to workers' day-to-day experience.
