Noise Pollution

What is Noise Pollution?

Noise pollution is unwanted or harmful noise that disrupts the natural environment. The word “noise” comes from the Latin word ‘Nausea,’ meaning sickness. Noise pollution can cause discomfort and health issues in humans. Sound intensity is measured in decibels (dB), with the faintest sound we can hear being 1 dB. Increasing noise from vehicles, aircraft, industrial machines, loudspeakers, and other appliances like TVs and radios has become a growing concern.
