Noise exposure in industrial environments is regulated by OSHA, with specific standards to conserve human hearing. Programs can be implemented to control the noise exposure of personnel around working machinery. We provide with comprehensive mapping of facilities or specific areas of human traffic. Need for PPE can be determined based on these maps. Regulations from OSHA compliance must meet the specifications in American National Standards Institute (ANSI) Standard S1.4 (OSHA, 2013). The ANSI standard sets tolerances for performance and accuracy (OSHA, 2013).
