Solution

The correct option is A 80 dB
The level of sound that can cause pain is called as noise. The level of sound for normal conversation is about 40-60 dB. Hence the level of sound above 80 is harmful, depending on how long and how often you are exposed to them and whether you wear hearing protection, such as earplugs or earmuffs. Thus, the correct answer is option C.
