Question

Q: How can noise levels be measured?​

Answer 1

Explanation:

When you measure noise levels with a sound level meter, you measure the intensity of noise called decibel units (dB). ... On the decibel scale, the quietest audible sound (perceived near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB.

Answer 2

Answer:

Noise may be measured using a sound level meter at the source of the noise. Alternatively,an organization or company may measure a person's exposure to environmental noise in a workplace via a noise dosimeter.
