Question

If the loudness of sound exceeds, it can cause harm to the human ear.

• A. $50\text{dB}$
• B. $75\text{dB}$
• C. $80\text{dB}$

Answer 1

The correct option is C $80\text{dB}$

In a normal conversation, we produce the sound of about $60\text{dB}$. However, if the loudness exceeds $80\text{dB}$, the sound becomes irritating and physically painful. Continuous exposure to such loud sound can cause hearing loss. ​​​​
