Final answer:
The statement is true; prolonged exposure to noise levels over 85 decibels can cause hearing damage. Protective measures like using earplugs and limiting exposure time are essential to safeguard against hearing loss, especially in loud environments like rock concerts.
Step-by-step explanation:
The statement that prolonged exposure to sounds over 85 decibels (dB) can damage hearing is true. Continuous or extended exposure to noise levels above 85 dB can lead to hearing damage or loss over time. To illustrate, noises at the level of a heavy truck inside the cabin can lead to hearing damage after prolonged exposure. Moreover, activities such as attending a loud rock concert or being near a jackhammer, which typically produce sound levels well above 85 dB, can result in even more immediate harm to one's hearing if protective measures are not taken. It is advisable to use earplugs, ear muffs, limit the duration of exposure, and maintain a safe distance from the noise source to prevent potential hearing damage.
