Traffic noise refers to the sound produced by vehicles on roads, including cars, trucks, buses, and motorcycles. This noise can vary in intensity and frequency, often depending on factors such as traffic volume, speed, and road conditions. It is commonly measured in decibels (dB) and can be a significant source of environmental pollution in urban areas. Exposure to high levels of traffic noise can have various effects on health and well-being. It may lead to sleep disturbances, increased stress levels, and even cardiovascular issues. Efforts to mitigate traffic noise include the use of sound barriers, improved road surfaces, and urban planning strategies that reduce vehicle congestion.
