Final answer:
Hearing loss can indeed result from chemical exposure in the workplace or from loud noise exposure, with sensorineural hearing loss being common due to damaged cochlear hair cells, which is often permanent.
Step-by-step explanation:
The statement 'Hearing loss can be caused by exposure to chemicals in the workplace.' is true. Workplace chemicals, such as certain solvents and metals, can contribute to sensorineural hearing loss alongside other factors like aging, head trauma, and infections. Prolonged or repeated exposure to loud noise, which is common in environments like construction sites or during the use of heavy machinery, can also damage hair cells in the cochlea, leading to hearing loss. For instance, operating a pneumatic chipper or attending a loud rock concert can bring about immediate damage if exposure lasts for a certain duration. Protecting one's hearing by limiting exposure to loud sounds or using protective devices like earplugs is essential for preventing hearing loss.
