Which set of noises can cause rescuer hearing damage?

Explanation:
Loud noises have the potential to damage rescuers’ hearing. In US&R environments, equipment, machinery, structural collapses, alarms, and blasts can produce very high sound levels. Hearing damage happens when intense sound energy overwhelms the delicate hair cells in the inner ear; this damage can be permanent and accumulates with both how loud the sound is and how long you’re exposed. Because of that, noises described as loud are the ones that pose a real risk to hearing, while softer, quieter, or moderate sounds are unlikely to cause damage within typical exposure times, especially when hearing protection is used and exposure is limited. In practice, always use hearing protection in loud work areas and minimize exposure to impulse or continuous loud noises to protect your hearing.
