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 like traffic volume, speed, and road conditions. It is commonly measured in decibels (dB) and can be a significant source of environmental noise 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 reduce traffic noise often involve sound barriers, better road design, and promoting quieter vehicles, such as electric cars.
