Question

Noise pollution is measured in units of:

• A. Lux
• B. Decibels
• C. Candella
• D. mg/L

Hint:

Noise levels are measured in decibels (dB). Continuous exposure to noise above 85 dB can cause hearing damage.

Answer 1

The Correct Option is B

Noise pollution is quantified using decibels (dB), which is a logarithmic unit that measures the intensity of sound. The threshold of hearing for humans is 0 dB, while levels above 85 dB are generally considered harmful to human health if exposure is prolonged.
