Depending on noise levels needing to be addressed, products include rigid wall panels or flexible curtains that create a quieted, moveable and expandable enclosure.
A wide variety of noise sources may exist in the workplace. The NIOSH Sound Level Meter App is a tool to measure sound levels in the workplace and provide noise exposure parameters to help reduce occupational noise-induced hearing loss.
Common Noise Levels A"decibel" is the unit to measure the loudness of sound. Decibel levels for each item shown in the graph may vary. If you need to raise your voice to be heard an arm's length away, the noise is probably loud enough to damage your hearing.
eNoise helps customers with the design of portable noise screens, sound partitions, sound blankets, barriers, and sound enclosures to help lower noise exposure to miners. You may be able to lower the time weighted decibel level below 90, 85, or 80 dBA with your plant action levels.
