Environmental noise refers to unwanted or harmful sounds in our surroundings, often originating from sources like traffic, construction, and industrial activities. This type of noise can disrupt daily life, affecting communication, sleep, and overall well-being. Commonly measured in decibels (dB), environmental noise can lead to health issues such as stress, hearing loss, and sleep disturbances. Efforts to manage and reduce environmental noise include urban planning, sound barriers, and regulations on noise levels from sources like vehicles and machinery.
