Acoustic walls, panels, or acoustic curtains reduce machine noise in the workplace to meet OSHA requirements for noise levels and employee safety. Industrial and manufacturing facilities that operate loud equipment can generate noise levels at dangerous levels that can affect employee safety. Production lines are typically run on hard and reflective surfaces, causing sound reverberations that can compound the problem. Along with this, the machinery itself produces a high level of noise and echo from motors, and the impact of grinding, pounding, sanding, cutting and other workplace activities. These extreme noise levels can damage the hearing of workers and often affect communication between personnel which can cause additional safety hazards.
