  • The special limit for people who are exposed to noise above 90 db is 8 hours, for 95 db is 4 hours and 2 hours for 100 db.
  • A short blast of loud sound also can cause severe to profound sensory neural hearing loss and pain. This usually involves exposure to noise above 120-155 db. Hearing protection in the form of muffins or ear plugs is highly recommended anytime a person is exposed to loud noise.
