Sound shields can be used to deflect the noise energy towards the absorbent ceiling materials. If remote operational control is an option, consider providing a separate insulated room to isolate the worker from the noise. The room should be constructed of materials with high transmission loss. To prevent leakage of noise into the room, gaps and spaces should be sealed between doors, windows and openings for piping or cables. Plan for noise control Noise control can be considered while planning a new building.
Heavy equipment requires rigid, heavy bases.
It also is possible to prevent the machine bases from making direct contact with the rest of the building frame. Surround significant noise sources with construction materials that provide sound isolation. Pay particular attention to portholes, observation windows and other building parts that involve a risk of sound leakage. Provide sound absorptive materials on walls and ceilings in noisy areas where the workers spend most of their time. The sound absorption capacity varies greatly for various materials, so materials should be selected in relation to the type of noise.
