Environmental noise refers to unwanted or harmful sounds in our surroundings, often resulting from human activities. Common sources include traffic, construction, and industrial operations. This type of noise can disrupt daily life, affecting communication, sleep, and overall well-being. Exposure to environmental noise can lead to various health issues, such as stress, hearing loss, and sleep disturbances. It is measured in decibels (dB), with higher levels indicating more disruptive sounds. Efforts to reduce environmental noise often involve urban planning, sound barriers, and regulations on vehicles and construction sites.
