  2. Hearing Conservation and Noise Control

  3. WHY?????? • It’s the LAW • Quality of Life • Gradual / Painless

  4. Anatomy of the Ear Pinna Semi-Circular Canals Auditory Nerve Cochlea Hammer-Anvil-Stirrup

  5. Types of Hearing Loss • Conductive • Central • Sensorineural

  6. Degree of Risk • Frequency • Intensity • Duration • Individual Variability

  7. How Loud is Loud? • Jet engine 140 db • Threshold of Pain 125 db • Pneumatic hammer 110 db • Compressed Air 105+ db • Punch Press 95 db • Lawn Mower 90 db • Conversation 65 db

  8. Noise Thermometer

  9. Personal Protective Equipmentadvantages / disadvantages • Cotton Balls • Canal Blockers • Ear Muffs • Ear Plugs • NRRs(example on next page)

  10. NRRs • EPA protocol • For “A” scale measurements NRR – 7 Noise exposure 92 dBA Manufacturer’s NRR 32 32 – 7 = 25 (effective noise exposure reduction) 92 – 25 = 67 dBA

  11. Exposure Limits • ACGIH 85 dBA (3 dBA) • NIOSH 85 dBA (3dBA) • OSHA 84 dBA (5 dBA) (Action Level) 85 - 89 dBA 90 dBA

  12. Noise Monitoring • Required by the OSHA standard to identify all noise above 80 dBA • Monitoring must be performed whenever there is an increase in production or equipment is added that could increase the noise level

  13. Audiograms

  14. Training requirements • Annual Training • Hearing Conservation Elements • Hearing Protectors

  15. Recordkeeping • Monitoring records • Audiometric testing records

  16. Noise Control • Engineering • Administrative • Personal Protective Equipment

  17. What we’re doing to control noise • Fill in here what you’re company is doing to reduce exposure to noise…….. • Reducing air pressure, • Enclosing loud operations or the operator, • Slowing cycle times, • Rotating workers, • Insulating equipment, breaking the path….
