Final answer:
Sounds louder than 70 dB can cause hearing damage, with exposure to 100 dB, such as from rock music or a jackhammer, leading to hearing loss in just 15 minutes. The threshold for pain is about 130 dB, and protective measures are recommended to prevent damage. The correct option is B) 70 dB.
Step-by-step explanation:
Exposure to sounds louder than 70 dB is likely to cause hearing damage. Sound levels like those of rock music or a jackhammer, which typically measure around 100 dB, can lead to noise-induced hearing loss after just 15 minutes of exposure.
Protective measures such as earplugs or earmuffs can be critical in preventing hearing damage when exposed to loud sounds. While the threshold for physical pain from sound is approximately 130 dB, sounds above 80 dB can also cause hearing damage over time. It's also important to limit exposure time and increase distance from loud sound sources to protect your hearing.
