When noise monitoring is required, what additional action is typically performed?

• A. No further testing is needed.
• B. Audiometric testing.
• C. Additional PPE is the only requirement.
• D. Replace hearing protection daily.

Answer: (B)

When noise monitoring shows exposures at or above set limits, audiometric testing is typically performed to protect workers’ hearing and track any changes over time. This testing establishes a baseline for each employee’s hearing and then monitors it periodically to detect early signs of noise-induced hearing loss. By comparing future results to the baseline, the organization can evaluate the effectiveness of controls, determine if hearing protection needs adjustment, and decide on any medical follow-up or engineering changes. The other options miss this ongoing health surveillance role: simply saying no further testing is needed ignores the purpose of monitoring; relying only on more PPE is not enough by itself; and replacing hearing protection daily is not a standard requirement tied to monitoring outcomes.
