| The above restrictions are based on the Occupational Safety and Health Act of 1970. That Code basically states that is\f the above exposures are exceeded, then hearing protection must be worn. Note that these are based on the “A scale” of a standard sound level meter at slow response and will change if some other standard is used.� See the OSHA Section 1910.95 for additional details on the differences. |
