Decibel is a measurement of the amount of pollution
The decibel (dB) is not a measurement of pollution. It is a unit used to express the relative intensity or power of a sound. Decibels are often used to measure and compare the noise levels emitted by various sources, such as machinery, music, or even environmental sounds like traffic or construction.
Pollution, on the other hand, refers to the presence of harmful or toxic substances in the environment that can have negative effects on living organisms and ecosystems. Pollution can take different forms, including air pollution, water pollution, noise pollution, and so on. The measurement of pollution usually involves the assessment of specific pollutants like particulate matter, chemicals, or gases, using different units and techniques depending on the type of pollution being measured.
