Which statement is correct? Noise may be:
a. Continuous, intermittent, steady, or a series of impact or impulse noises and
the longer the exposure, the greater the damage to the hearing mechanism.
b. Continuous, intermittent, steady, or a series of impact or impulse noises and
the shorter the exposure, the greater the damage to the hearing mechanism.
c.
Of greater damage to inanimate objects.
d. Part of overall efficiency.
33.
The hearing conservation program can be an effective means to prevent hearing
loss from exposure to excessive job-related noise if careful coordination involves:
a
Engineering control measures, medical control measures, and health
education.
b. Personal protective measures and personal discipline on the part of workers.
c.
Proper supervision and an effective implementation of the hearing
conservation program.
d. All of the above.
34.
What is the first step in establishing a hearing conservation program?
a. Check the noise impulse.
b. Determine steady noise.
c.
Conduct a noise survey.
d. Determine the standards.
35.
Under what circumstances might a noise survey be conducted? When personnel:
a. Have difficulty communicating by speech while they are in the noise area.
b. Hear noises or ringing sounds in their ears after working in the noise area for
several hours.
c.
Experience temporary loss of hearing, which muffles speech and certain other
sounds, after several hours of exposure to the noise.
d. All of the above.
