In a Hearing Conservation Program, what is the purpose of baseline audiometric testing?

• A. To monitor environmental noise levels in the workplace
• B. To establish a reference baseline and identify baseline hearing status for comparison
• C. To track equipment maintenance needs
• D. To assess general health unrelated to hearing

Answer: (B)

Baseline audiometric testing creates a personal reference for a worker’s hearing. It measures the individual’s hearing thresholds across the frequency range to establish their initial hearing status before or at the start of exposure to workplace noise. That reference is then used to compare future audiograms over time, so any threshold shifts can be detected early and addressed with protective actions or medical follow-up. This approach also helps determine who needs to participate in the hearing conservation program and how monitoring should proceed. It isn’t about measuring environmental noise, tracking equipment maintenance, or assessing general health unrelated to hearing, which is why the established purpose is to set that baseline and enable meaningful comparisons over time.
