According to the Centers for Disease Control (CDC), some 22 million U.S. workers are currently exposed to hazardous noise conditions. Excessive workplace noise is linked not only to hearing loss, but also to a host of other medical conditions, including cardiovascular diseases such as hypertension, arteriosclerosis, and coronary heart disease (CHD).

Industrial plants are known for being loud, acoustically-harsh environments. The combination of high ceilings, reflective surfaces and heavy machinery din creates an environment for reverberation and noise. Such conditions can decrease productivity and increase health and safety hazards.
