Who is responsible for conducting audiometry and also stocks and fits hearing protection devices (HPDs)?

An occupational hearing conservationist is specifically trained to conduct audiometry as part of a broader hearing conservation program, which aims to prevent hearing loss due to workplace noise exposure. In addition to performing hearing tests, they also have the expertise to assess the adequacy of hearing protection devices and ensure that they are properly fitted and stocked for employees. This role is critical in workplaces where noise levels can be hazardous, providing both testing and preventative measures to protect workers' auditory health.

The other roles mentioned—workplace supervisor, occupational health nurse, and audiologist—each have distinct responsibilities but do not encompass the full spectrum of duties involved in a hearing conservation program in the same way. For instance, while an audiologist can conduct audiometric testing and provide a higher level of clinical support for hearing issues, they may not be routinely involved in the fitting and stocking of hearing protection devices in the workplace setting. A workplace supervisor oversees general employee health and safety, and an occupational health nurse focuses on overall employee health and workplace wellness, which does not directly include the specialized responsibilities related to conducting audiometry and managing hearing protection.
