HEARING PROTECTION (MIOSHA Standards R325.60121 – R325.60122)

All employees exposed to 85dB(A) TWA noise must have available hearing protectors. It is the employer's responsibility to ensure such hearing protectors are worn by employees:

• whose noise exposure exceeds 90dB(A) TWA; or
• whose exposure equals or exceeds 85dB(A) TWA and have not yet had a baseline evaluation;
  or
• who have experienced a Standard Threshold Shift (STS)
• who have shorter periods of exposure to higher levels of noise (see Table I).

The adequacy of hearing protector attenuation shall be reevaluated whenever noise exposure increase.
