veistøy

Veistøy, also known as road traffic noise, refers to the sound produced by vehicles on roads. It is a significant environmental concern in many urban and suburban areas, impacting the quality of life for residents. The primary sources of veistøy include tire-road interaction, engine noise, exhaust systems, and aerodynamic noise generated by the vehicle's movement through the air. The intensity and characteristics of this noise can vary greatly depending on factors such as traffic volume, vehicle speed, road surface type, and the presence of noise barriers.

The health effects of prolonged exposure to excessive veistøy are well-documented. These can range from annoyance and sleep disturbance to more serious issues such as cardiovascular problems, hypertension, and cognitive impairment, particularly in children. Consequently, measures to mitigate veistøy are a priority for urban planners and transportation authorities. These strategies often involve a combination of approaches.

Common mitigation techniques include improving road surface materials to reduce tire-road noise, implementing traffic calming measures to lower speeds, and enforcing noise regulations for vehicle emissions. The construction of noise barriers, such as walls or earth berms, along major roadways is another effective method for deflecting sound away from residential areas. Furthermore, promoting quieter vehicle technologies and encouraging shifts towards public transportation or active mobility options like cycling and walking can contribute to a reduction in overall veistøy levels.
