5')' Noise: OSHA uses a 5 dB exchange rate, while NIOSH, ACGIH, the DoD, and other organizations use or recommend a 3 dB exchange rate. Research and explain in your own words what that means. Why do you think OSHA is different (do some research on this)? Should OSHA be different? If OSHA changed to a 3 dB exchange rate, what impact would that have on employers? What impact would changing from a 5 dB exchange rate to a 3 dB exchange rate have on employees? Which is more protective? Since OSHA regulations are "minimum standards" for employers, should employers be more protective when establishing a hearing conservation program for employees
