What is the #1 occupational health hazard in the military? - Answer-hearing loss
Unprotected exposure to hazardous noise can cause the following: - Answer-temporary hearing loss,
permanent hearing loss, and/or tinnitus
How does noise induced illness occur? - Answer-gradually over time from repeated exposures
How does noise induced injury occur? - Answer-occurs from one significant exposure or event
What are some DoD related occupational noise sources? - Answer-machinery, weapons, vehicles, tools,
and equipment

manufacturing
What are some non-occupational noise sources? - Answer-lawn care, power tools/equipment, firearms,
music, and motorcycles
What are auditory effects of noise exposure? - Answer-loss of hearing sensitivity, tinnitus, missing parts
of conversation, slower, inaccurate auditory localization, increased errors or safety mishaps
What are non auditory effects of noise exposure? - Answer-high blood pressure, increased heart rate,
increase stress hormone levels, disrupt healthy sleep patterns, possible reassignment to different MOS,
embarrassment frustration or withdrawal
What are the four P's of NIHL? - Answer-painless, progressive, permanent, and preventable
What is the purpose of the Hearing Conservation Program (HCP)? - Answer-prevent occupationally
related NIHL, maintain combat readiness, maintain fitness for duty, retain job or work specialty, reduce
cost of hearing loss, and promote healthy hearing and quality of life
What are the major elements of the hearing conservation program (HCP)? - Answer-noise hazard
assessment, noise controls, audiometric monitoring, hearing protection devices (HPDs), hearing
conservation education, recordkeeping, program evaluation

- Answer-ensure uniform standards of practice for an audiometric monitoring program
What is the role of a Occupational Hearing Conservationist/Hearing Technician? - Answer-test all
personnel, fit HPDs, educate and MOTIVATE, answer questions, process referrals to the correct echelon
of care
What are the characteristics of sound? - Answer-frequency, amplitude, and temporal/time
What is frequency? - Answer-referred to as pitch described as a high-pitched sound like a train whistle
or a low-pitch sound like the rumble of thunder or engine noise
How is frequency measured? - Answer-measured in hertz (Hz)
What is a high pitched sounds typically described as? - Answer-frequencies greater than 2000 hz
What is a low pitched sound typically described as? - Answer-usually less than 500 Hz
What is amplitude? - Answer-referred to as intensity or loudness and is measure in decibels (dB); the
louder the sound the higher the decibel number
What is temporal/time? - Answer-how the sound changes over a period or time
What are the technical terms for temporal/time? - Answer-continuous, steady state, intermittent,
varying, impact, and impulse
