Which of the following records is NOT required to be maintained for hearing conservation?

Maintaining records for hearing conservation programs is essential for ensuring compliance with occupational safety and health regulations related to noise exposure. Audiometric calibrations, training records, and noise assessment surveys are requirements under various regulations, such as OSHA's guidelines. These records provide necessary documentation that helps monitor and evaluate a hearing conservation program's effectiveness.

Audiometric calibrations ensure that the equipment used for hearing tests is functioning accurately, which is vital for identifying hearing loss in employees. Training records demonstrate that employees have received the necessary information about hearing conservation, noise exposure risks, and the proper use of hearing protective devices. Noise assessment surveys evaluate the levels of noise exposure in the workplace, helping to identify areas where hearing conservation measures are needed.

On the other hand, employee satisfaction surveys are not a mandated part of hearing conservation programs. While useful for overall workplace morale and conditions, they do not directly relate to the regulatory requirements surrounding hearing conservation or occupational noise exposure. This distinction makes it clear why employee satisfaction surveys are not required.
