CAOHC Program Evaluation and Effectiveness Metrics

Question 1

What is the primary purpose of evaluating a hearing conservation program's effectiveness?

Accepted Answer

To determine whether the program is preventing occupational hearing loss as intended

Answer

To justify the program's elimination to save costs

Answer

To compare the program to competitors in other industries

Answer

To prepare for marketing the program to other companies

Question 2

Which metric is most commonly used to assess the overall effectiveness of a hearing conservation program?

Accepted Answer

Standard Threshold Shift (STS) rate among enrolled workers

Answer

Number of hearing protectors distributed

Answer

Annual training attendance rate

Answer

Cost per audiometric test

Question 3

What is an 'audiometric database analysis' (ADBA) and how is it used in program evaluation?

Accepted Answer

Statistical analysis of audiometric records across the workforce to identify trends, compare groups, and assess prevention effectiveness

Answer

A database of audiometric booth locations

Answer

An inventory of all audiometers in the program

Answer

A list of workers who have refused audiometric testing

Question 4

What is considered an acceptable STS rate for a well-managed hearing conservation program?

Accepted Answer

Less than 5% of enrolled workers per year

Answer

Less than 25% of enrolled workers per year

Answer

Less than 50% of enrolled workers per year

Answer

Any STS rate is acceptable as long as the program exists

Question 5

What does it mean when a hearing conservation program has a higher STS rate in one department compared to others?

Accepted Answer

That department may have higher noise exposure, poorer hearing protector use, or less effective program implementation

Answer

The audiometer used for that department is miscalibrated

Answer

Workers in that department have genetically weaker hearing

Answer

It is a random variation with no actionable meaning

Question 6

What role does noise exposure monitoring data play in program effectiveness evaluation?

Accepted Answer

It establishes whether worker exposures are being adequately controlled and identifies areas needing additional intervention

Answer

It is only used for OSHA compliance, not program evaluation

Answer

Noise data has no relationship to program effectiveness

Answer

It only matters for workers above the PEL, not the action level
