Question: 1 / 400

What is the goal of hearing protection devices (HPDs)?

To monitor heart rate

To protect against heat strain

To prevent hearing loss

Hearing protection devices (HPDs) are specifically designed to protect against noise-induced hearing loss, which occurs when the sensitive hair cells in the inner ear are damaged by loud sounds. A and D are incorrect because they refer to functions not related to preventing hearing loss. Monitoring heart rate and regulating body temperature are functions of other types of devices or monitoring methods. B is incorrect because heat strain is not a concern when it comes to hearing protection. Additionally, HPDs typically do not provide any protection against heat.
