Question

The maximum level of tolerable noise pollution for human being is

• A. $60$ decibels
• B. $70$ decibels
• C. $80$ decibels
• D. $100$ decibels

Answer 1

The correct option is C $80$ decibels

The noise level of 80 decibels or more for more than 8 hours a day increases tension and changes in breathing patterns. Continued exposure to high levels of noise results in fatigue, hearing loss or even total loss of hearing, changes in blood circulation, changes in breathing, etc.

So the correct answer is '80 decibels'.
