Question

Noise pollution is measured in:

• A. Ohm
• B. Decibel
• C. Joule
• D. Ampere

Hint:

When measuring noise levels, remember that decibels (dB) represent the intensity of sound, and a higher dB level indicates louder sound.

Answer 1

The Correct Option is B

Step 1: Understanding noise pollution.
Noise pollution refers to harmful or unwanted sounds that can impact health. To measure noise pollution, we use the decibel (dB) scale, which quantifies sound intensity.
Step 2: Analyzing the options.
- (A) Ohm: Ohm is a unit of electrical resistance and is not used to measure sound.

- (B) Decibel: Decibels are the unit used to measure the intensity of sound and noise pollution.

- (C) Joule: Joule is a unit of energy, not sound.

- (D) Ampere: Ampere is a unit of electric current, not sound.
Step 3: Conclusion.
The correct answer is (B) Decibel, as it is the unit used to measure noise pollution.
