Question

a technician is working at a tire installation shop and is constantly using an impact gun that produces 100 decibels. what type of ear protection is recommended to be worn for protection?

○ a. only the over the ear style should be worn.
○ b. only the in the ear canal style should be worn.
○ c. either the over the ear or in the ear style would be fine.
○ d. neither the over the ear or in the ear style should be worn.

Explanation:

For 100 decibels, both over - the - ear (earmuffs) and in - ear (earplugs) hearing protection can effectively reduce noise exposure. They both have sufficient noise - reduction capabilities for this level of noise, so either can be used.

Answer:

c. Either the over the ear or in the ear style would be fine.
