This paper analyzes measurements of sound pressure levels on construction sites in Brazil to argue for better worker protection. The measurements provide valuable evidence to support better worker protection, but the manuscript would benefit from a more comprehensive discussion of the effectiveness of control measures.

For example, the authors suggest rearranging machinery to limit the number of workers exposed to their noise, but I would have liked to read at least a cursory analysis of how much such measures can reduce noise, and whether administrative or engineering solutions can sufficiently meet safe noise thresholds. If such analysis wasn't conducted within the scope of this work, then literature review could inform such discussion.
