What must be done if a significant decrease in hearing is detected?

When a significant decrease in hearing is detected, it is essential to refer employees for follow-up care. This step ensures that individuals receive the appropriate medical evaluation and intervention needed to understand the cause of the hearing loss and to prevent further damage. Early referral can lead to prompt diagnosis and treatment, which is vital for managing hearing health effectively.

Addressing hearing loss proactively helps employees maintain their auditory health and can also enhance workplace safety and productivity. Follow-up care may include further audiometric testing, consultation with an audiologist or otolaryngologist, and potential adjustments in workplace practices or hearing conservation programs.

While the other options imply actions that may seem necessary, they do not directly address the primary concern of treating and managing hearing loss. Time off may not be required; warning letters do not provide the necessary medical attention; and transferring to another department could overlook the critical need for assessment and intervention regarding the hearing issue.
