Sound Pollution Assessment Lab
Sound pollution, or noise pollution, is unwanted or harmful sound that disrupts the environment. The decibel (dB) scale measures sound intensity logarithmically, meaning each 10 dB increase represents a tenfold increase in sound intensity. Prolonged exposure to sounds above 85 dB can cause hearing damage, while levels above 120 dB can cause immediate harm. Smartphone apps use the device's microphone to estimate sound levels, but their accuracy can vary based on microphone quality, calibration, a
