Chapter 7 & 8 CAOHC Study Guide
Education and training is an OSHA annual requirement for all employees with noise exposure
levels of ___________ TWA or greater - ANS-85 dBA
3 OSHA required hearing conservation education and training topics - ANS-- effects of noise on
hearing
- purpose of hearing protectors/advantages/disadvantages/selection/fitting/care/use
- purpose of annual hearing test and explanation of procedures
types of employee education and training - ANS-- personalized 1:1
- group
- computer based
- handouts/booklets
- audiovisual materials
-other resources
characteristics of NIHL - ANS-- does not produce loss greater than 75 dB HL in high frequencies
and 40 dB HL in the lower frequencies
- typically bilateral, notching HL pattern at 4000 Hz (3000-6000 Hz)
baseline audiogram - ANS-- required by OSHA
- first test conducted with a new employee
- OSHA requires employees to be "noise free" for 14 hours prior to baseline test (HPD counts)
- must be accomplished within 6 months of employees first noise exposure for onsite testing
- must be accomplished within 12 months of employee's first noise exposure if using mobile test
annual audiogram - ANS-- required by OSHA annually for employees exposed to hazardous
noise levels
- annual OSHA PTA compared to baseline OSHA PTA results
- no noise free requirement
- can be conducted anytime during the work shift
retest audiogram - ANS-- maybe obtained within 30 days of annual audiogram to confirm
presence of standard or significant threshold shift identified on the employee's annual
audiogram
- should be conducted at least 24 hours after annual audiometric monitoring test
- NOT required by OSHA
exit audiogram - ANS-- final test before worker leaves the company's employment
- NOT required by OSHA
