Noise Testing and Hearing Protection in High-Risk Workplaces
Excessive workplace noise remains one of the most common—and preventable—causes of occupational hearing loss across a wide range of industries. Whether it’s the impact of heavy machinery, continuous equipment operation, or even the synergistic effects of noise and chemical exposure (such as solvents), unmanaged sound levels can cause irreversible damage to workers’ hearing.
At Central Industrial Hygiene Partners (CIHP), we specialize in occupational noise exposure assessment and control. Our certified professionals—including Certified Industrial Hygienists and Hazardous Materials Technicians—have the training and tools to evaluate workplace sound exposure and design practical solutions that reduce risk and ensure compliance with OHS regulations.
