What is a primary approach to reduce noise-induced hearing loss in the workplace?

Participation in audiometric testing is a primary approach to reduce noise-induced hearing loss in the workplace because it serves multiple critical functions. Audiometric testing is designed to assess an individual's hearing ability and detect any early signs of hearing loss caused by excessive noise exposure. This testing can identify employees who may already be experiencing hearing issues, allowing for timely intervention.

Moreover, regular audiometric testing raises awareness among employees about the effects of noise exposure on their hearing health, prompting them to engage in protective measures. It also helps employers identify areas in the workplace that may require noise mitigation strategies or the need for personal protective equipment like earplugs or earmuffs. By establishing a routine of audiometric testing, workplaces can proactively manage noise levels and promote a safer auditory environment, effectively reducing the risk of noise-induced hearing loss.

The other options do not directly contribute to reducing noise exposure or managing its consequences as effectively as audiometric testing does.
